Micro Differential Pressure Transmitter Air DP Sensor with 0.5% Accuracy 500pa
BP93420DI Differential Pressure Transmitter
The BP93420DI is a micro-differential pressure transmitter that utilizes semiconductor silicon piezoresistive technology to convert differential pressure into electrical signals. Designed for measuring small differential pressures of non-corrosive dry gases, this transmitter is ideal for boiler air supply, underground ventilation in power and mining industries, and pressure monitoring in ultra-clean workshops.
