The detector has handheld carbon dioxide detector, fixed carbon dioxide detector, portable carbon dioxide detector and so on. The basic parameters are similar. Here I will only introduce you to a fixed carbon dioxide detector that I personally think is good.
Product Description: Fixed carbon dioxide detector with display. Some also called with display carbon dioxide probe, with display carbon dioxide transmitter, with display fixed carbon dioxide detector or with display carbon dioxide sensor and so on. The role of the device is to be installed in the field real-time monitoring of the gas concentration and the detected concentration in the instrument display shows up. At the same time, the carbon dioxide gas concentration detected at the scene is converted into corresponding standard voltage signals (such as 0-5V), current signals (such as 4-20mA), standard digital signals (such as bus RS485, RS232), frequency signals, Hart protocol signals, CAN2.0 bus signals and other signals, and then the signals are sent to the PLC, DCS, the alarm control mainframe and other host computer for unified display, management and control. Unified display, management and control. The fixed carbon dioxide detector with display has two relays (switching signals) inside, which can control the sound and light alarms, fans, solenoid valves and other equipment.
Fixed carbon dioxide detector with display features:
★? Explosion-proof design: The circuit of fixed carbon dioxide detector with display is designed according to the national intrinsic safety requirements, and its product shell is also certified by the national explosion-proof. And the product has obtained the national explosion-proof certification. The product explosion-proof type is ExdⅡCT6?Gb?
★? Multi-function display: The instrument can display the current concentration of the detected gas and the current time and other data in real time.
★? Convenient operation: When you need to set up the instrument, such as alarm upper and lower limit value setting, time setting, output signal selection and other operations. You can use the remote control or open the top cover of the finished product to operate in two ways.
★? Full-featured: Ampal's fixed carbon dioxide detector with display is very perfect in the industry no matter from the power supply selection, standard signal output selection, range selection, detection mode and other choices, almost can meet your technical requirements.
★? Rainproof and corrosion-resistant design. Fixed carbon dioxide detector with display can be used in the field, chemical plant, sea and other environments with rain and easily corrosive and strong.
★? Easy to install and use: Ampahl's carbon dioxide detector with display adopts humanized design in the installation of equipment, wiring and other aspects of use. All are standing in the field construction personnel point of view, all to facilitate the use of field construction personnel of mature products.
★? High precision: carbon dioxide detector with display using a well-known brand of core sensor accessories, advanced hardware and filtering technology, the environment leads to error compensation technology to ensure the high accuracy of the product.
★? Easy maintenance and replacement: In line with the principle of allowing customers to spend less money, but also the fastest speed to update the equipment. Ampahl's carbon dioxide detector with display in the subsequent use of the product need to replace parts and maintenance, are very convenient. That will minimize the lack of equipment caused by the lack of normal construction and production losses.
★? Low failure rate, stable and reliable: After years of use in the petrochemical, electric power, medical, agricultural, aerospace, mining and other environments around the world, the carbon dioxide detector with display extremely low failure rate. For Ampahl high speed has won a good reputation and high turnover rate. Choose Ampahl you can be more assured!
★? With automatic calibration function: carbon dioxide detector with display some with automatic calibration function, reduce the detection error caused by sensor drift.
★? Communication and self-diagnostic function. The instrument can be self-diagnostic to derive the current state of the equipment operating conditions. Such as viewing, setting, calibration, alarm point setting and so on.
