Product Description
Aluminium Case HVAC Differential Digital Air Pressure Sensor Transmitter

BP93420DI Differential Pressure Transmitter
The BP93420DI differential pressure transmitter accurately measures differential pressure through a Wheatstone bridge sensor chip. When differential pressure acts on the corrugated diaphragms at both ends of the sensor, the output signal exhibits excellent linear relationship with the pressure differential. This transmitter is ideal for various gas and liquid differential pressure measurements in petroleum, chemical, power, and hydrology industries for pipeline applications.
