PPM-T230E-230 Explosion-proof pressure transmitter
Product Introduction:
PPM-T230E-230 series is our company's product specially designed
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.
