Explosion Proof PPM-T230E-222 Wellhead Pressure Equipment Pressure Transmitter
Product Introduction:
The PPM-T230E-222 series is a product designed by our company for high-explosive hazardous places or working conditions. It uses imported premium materials and advanced MEMS technology to process into an integrated pressure core, which is equipped with a precision processing circuit. The temperature signal can be compensated, and it can output 4-20mA, 0-5VDC, 1-5VDC, 0-10VDC standard signals. It has the characteristics of high accuracy, anti-interference, strong overload and impact ability, moisture resistance and long-term stability. Time directly measures -196 ℃ liquid, no need to extend the tube, making the measured value true and reliable. A variety of pressure interfaces and electrical interfaces are available for customers to choose to meet the pressure measurement of various industrial processes.
This product has passed the explosion-proof certification of the Quality Supervision and Inspection Center of explosion-proof electrical products.
