Introduction
PT115X/PT125X/PT135X series explosion-proof melt pressure sensor is an intelligent 4…20 mA HART protocol melt pressure transmitter. Special film and high-temperature wear-resistant coating make it work normally at 400 ℃ high temperature, using the standard threaded connection to install, full 4-digit display, relay output is optional. High stability and long service life. The intrinsically safe high-temperature melt pressure transmitter is designed for hazardous explosion-proof areas and remote control, and the wireless module can be customized.
Application
PT115/PT125/PT135 explosion proof melt pressure transmitter is specially designed for pressure monitoring of liquid, gas or paste-like substances at high temperature. They must be liquid, gaseous or viscous flow. Under normal use, the pressure does not exceed the upper limit of the measurement range, and the instantaneous pressure does not exceed the upper limit of the measurement range by 150 (based on the diaphragm surface). Any use beyond the scope of the above application does not comply with the regulations.
