Product Description

HTsensor Micro Differential Air Gas Pressure Transmitter Sensor with 4-20mA

BP93420DI Differential Pressure Transmitter

The BP93420DI is a micro-differential pressure transmitter that utilizes the piezoresistive effect of semiconductor silicon material to convert differential pressure into an electrical signal. It is designed for measuring small differential pressures of non-corrosive dry gases, making it ideal for applications in boiler air supply, underground ventilation in power and mining industries, and pressure automatic detection in ultra-clean workshops for process control.
