The product structure is reasonably designed, accurate detection, performance
stable performance, easy to install and maintain. It is suitable for underground coal mine
with coal dust, gas explosion hazardous places, it is usually used with
display instrument, recording instrument and all kinds of control system
set. It has high measurement accuracy, strong anti-interference ability, and the external
type adopts the fully sealed stainless steel structure, which can meet the requirements of moisture-proof,
explosion-proof, anti-corrosion, dust-proof and other harsh working conditions.
2, working principle
KGHY330 mine intrinsically safe pressure transmitter is the core component of the diffusion of silicon pressure sensitive components. The principle is the use of ion implantation in the silicon substrate and laser correction to form a Wheatstone bridge, external pressure on the sensor's isolation diaphragm so that the diaphragm displacement, through the membrane box of the silicone oil will be the pressure transferred to the silicon substrate, so that the Wheatstone bridge of the four resistors, two due to the resistance of the stretch and the resistance becomes small, the other two due to the resistance of compression and the resistance of the bridge arm to make the bridge out of balance, so that the bridge generated a voltage proportional to the pressure, and the pressure is proportional to the pressure. A voltage output signal proportional to the pressure. The millivolt signal of the sensor is processed by an integrated amplifier circuit and converted into an industry standard 4-20mA signal output.
