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.
Product Features

- Lightweight and easy to install
- Rigorously tested for high and low-temperature performance
- High accuracy measurement
Applications
- Boiler and mining industries
- Brewing and power industries
- Detection of small differential pressures in non-corrosive gases
