Oh, come on.
I hope to adopt.
Question 2: What does the instrumentation class include? Instrumentation is a variety of scientific and technological synthesis product, a variety of varieties, widely used, and constantly updated, there are a variety of categorization methods. According to the use of purpose and use to points, the main gauge gauge, automotive instrumentation, tractor instrumentation, marine instrumentation, aviation instrumentation, navigation instruments, driving instruments, radio test instruments, carrier microwave test instruments, geological exploration test instruments, building materials test instruments, seismic test instruments, geodetic surveying and mapping instruments, hydrological instruments, timing instruments, agricultural test instruments, commercial test instruments, teaching instruments, medical instruments, environmental protection instruments and so on. Environmental protection instruments, etc. Instrumentation classification of machinery industry products belong to the machinery industry products of instrumentation are industrial automation instrumentation, electrical instrumentation, optical instruments, analytical instruments, laboratory instruments and devices, material testing machines, meteorological and oceanographic instruments, film machinery, photographic machinery, photocopying and microcopying machinery, instrumentation components, instrumentation materials, instrumentation equipment and other thirteen types of technology. They are more versatile, larger batch, or for the instrumentation industry is necessary for the foundation. Classified according to different characteristics of various types of instruments according to different characteristics, such as function, detection and control of objects, structure, principle, etc. can also be divided into a number of subclasses or subclasses. Such as industrial automation instrumentation according to function can be divided into detection instrumentation, loop display instrumentation, regulating instrumentation and actuators, etc.; which detection instrumentation according to the measured physical volume is divided into temperature measurement instrumentation, pressure measurement instrumentation, flow measurement instrumentation, level measurement instrumentation and mechanical measurement instrumentation, etc.; temperature measurement instrumentation according to the measurement method is divided into contact temperature measurement instrumentation and non-contact temperature measurement instrumentation; contact temperature measurement instrumentation can be divided into Thermoelectric, expansion, resistance and so on. Other classification methods of other types of instruments and meters of the classification method is similar, mainly with the development process, the use of customary and related products related to the classification. Instrumentation in the classification is not yet a unified standard, instrumentation naming also exists in a similar situation. In reality, we often instrumentation is divided into two categories: automation instrumentation and portable instrumentation, automation instrumentation refers to the need for fixed installation in the field of instrumentation, also known as field installation instrumentation or dial installation instrumentation, this type of instrumentation needs to be used in conjunction with other equipment in order to complete a certain function or several functions; portable instrumentation refers to the use of a separate, and sometimes also called test Portable instrumentation refers to the separate use, sometimes also called detection instrumentation, generally divided into desktop and handheld two kinds. Instrumentation there is a classification, called primary instrumentation and secondary instrumentation, primary instrumentation refers to sensors such as direct sense of the measured signal part of the secondary instrumentation refers to the amplification, display, transfer signal part.
Question 3: Which program does instrumentation belong to? Some colleges and universities specialize in instrumentation, and instrumentation belongs to the instrumentation program.
Some colleges and universities also categorize instrumentation as an automatic control or electronic technology program.
Problem 4: Instrumentation manufacturing belongs to what specialties Instrumentation class specialties
Problem 5: Thermal instrumentation is the abbreviation of what specialties Automation, now in the heavy industrial enterprises, thermal instrumentation is basically an independent type of work, or a combination of automation
Problem 6: Vocational high school inside the learning instrumentation specialization is what Don't go to the vocational high school, now the vocational high school is really not anything, or go to a technical school. Prospects, or to go to a technical school, learn a Sichuan cuisine, now the development of Sichuan cuisine is only good
Question 7: instrumentation during the internship what are doing I was engaged in the instrumentation of the main learning is the four parameters: pressure, flow, level, temperature. First of all, we have to understand them, know the principle, learning is much easier. I will say a few important process-related it! 1 , spring tube pressure gauge pop-up tube, also known as the Borden tube, is a tube bent into an arc, spiral or S-shaped and other shapes, into a flat circle or oval. The direction of the short axis of the cross-section and the radial direction of the tube bending the same. When the pressure into the spring tube is higher than the pressure outside the tube, due to the short-axis direction of the internal surface area than the direction of the long axis, the force is also large, so that the tube cross-section has a tendency to become rounded. That is, the short axis in the longer, the long axis to become shorter, resulting in elastic deformation, when the free end is bound to move in the direction of the tube straightening. When the deformation caused by the elastic force and the pressure generated by the force balance, the deformation stops. The displacement of the free end, through the lever drive amplification mechanism, so that the pointer deflected by a certain angle, with the help of the dial to indicate the size of the measured pressure value. 2, thermocouple thermocouple temperature meter is currently the most widely used kind of temperature meter, thermocouple temperature meter is a kind of temperature electric measuring instrument, it usually consists of thermocouple, thermocouple cold end temperature compensation device (or element) and display instrumentation of the three parts, the three are connected with wires. Thermocouple temperature measurement principle Thermocouple is formed by welding one end of two different conductors or semiconductor wire material A and B, A, B is called the heat electrode (or thermocouple wire). Welded up one end placed at the measured temperature t, known as the hot end of the thermocouple (or measurement end, working end); non-welded end is called the cold end (or reference end, free end), the cold end is placed outside the object to be measured at a temperature of t0 in the environment. If the two cold ends of the thermocouple is also connected to form a closed loop, as shown in Figure 2-1, when the temperature of the hot end and the cold end of the temperature is not equal, i.e., t ≠ to, there is a current flow in the loop, which indicates that in the loop generated electric potential, due to the thermocouple two points of contact at the temperature is different and the electric potential generated is called thermoelectric (dynamic) potential, the above rationale is called the thermoelectric effect, or known as the Seebeck effect. Thermocouple is the use of thermoelectric effect to measure temperature. Further research shows that the thermoelectric potential is composed of contact potential and temperature difference electricity. 3 、1151 Differential Pressure Transmitter When the measured pressure acts on the isolation diaphragm, the filling liquid transfers the pressure to the center of the filling liquid, and the center of the filling liquid transfers the pressure to the sensing diaphragm of the δ-chamber sensing center. The sensing diaphragm is a tensioned elastic element whose displacement varies with the differential pressure applied. And the displacement is proportional to the pressure, both sides of the capacitance plate to detect the position of the sensing diaphragm, sensing diaphragm and capacitance between the plate capacitance difference is converted to the corresponding current, through the output circuit output 4 ~ 20mA DC current. 4, electrical valve positioner Electrical valve positioner is designed to work according to the principle of force balance, its operating principle is based on the pneumatic valve positioner developed from the current signal control valve positioner. When the current signal from the electric regulator, input to the coil of the torque motor assembly, in the air gap of the torque motor to produce a magnetic field, it and the magnetic field produced by the permanent magnet *** with the role of the armature to produce a force to the left, the main lever (armature) around the fulcrum (15) rotation, the gear plate close to the nozzle, the back pressure of the nozzle by the amplifier amplifier, into the thin-film actuator chamber, so that the valve lever downward movement, and drive the feedback lever rotating around the pivot, connected to the valve positioner. Feedback lever rotation around the fulcrum, connected to the same axis of the feedback cam for counterclockwise main direction of rotation, through the roller so that the pay lever around the fulcrum rotation, and the feedback spring (11) stretch, the spring on the main lever tension and torque motor acting on the main lever torque is equal, the mechanical lever system to reach a state of equilibrium. At this point, a certain signal current corresponds to a certain person valve position. The spring is used for adjusting the zero position. The above mode of action for the positive action, if you want to change the mode of action, as long as the cam flip, A to become B, etc., can be. The so-called positive-acting positioner is that the signal current increases and the output pressure also increases; the so-called negative-acting positioner is that the signal current increases and the output pressure decreases. A positive-acting actuator as long as the installation of the reaction positioner, can realize the action of the reaction actuator; on the contrary, a reaction actuator as long as the installation of the reaction positioner, can realize the action of the positive-acting actuator Make a reference to it

Problem 8: Learning to instrumentation, what are the books about the instrumentation. On the chemical press online bookstore, which is a lot of specialized books on instrumentation.
Applicable to a little bit of "chemical automation and instrumentation", "Instrumentation Repairer", "chemical measurement and instrumentation", "Instrumentation Worker Exercise Set" and so on, these are instrumentation of the comprehensive knowledge of the book.
Question 9: Instrumentation industry specifically do what? Instrumentation is used to measure and control a variety of processes in a variety of parameters (variable) amount of tools or systems. Instrumentation industry jobs include manufacturing, sales, research and development, design, maintenance and so on.
Usually the so-called instrumentation industry jobs refer to the instrumentation maintenance work, technical management work inside the factory.
Problem 10: instrumentation professional how these two industries are good, industrial and mining enterprises now need such talent, personal feeling automation direction better, but just personal advice, different areas of the two industries may not be the same requirements. If you have someone in your family or have money, it is better to enter the automation institute and other institutions. I don't know what your internship stage is about, so start now to make time to contact jobs, send more resumes, and if you are close to home or school, it is best to go directly to the unit to seek employment. Good luck!
