Wireless pressure transducer features

PM450C Wireless pressure transducer with dual temperature measurement is suitable for pressure monitoring of petroleum oil and water well production, storage and transportation process. It adopts micro-power wireless communication mode, no wiring is required, installation is faster, safer and more convenient. It has built-in high- precision pressure sensor, which can accurately display the pressure and temperature in real time, and has the characteristics of high stability and long-term stability.This type of digital pressure gauge is equipped with large-scale HD LCD display and built-in MCU. With mature Lora/4G/IOT network, the on-site pipeline pressure and temperature is uploaded to the data center

Or, it is can be matching with wireless switching device, which can convert many wireless pressure and temperature signals into MODBUS standard signals and transmit them through Ethernet or serial port.
