Product Description

Through the connection of the air pressure transmitter and the control instrument, the differential pressure
at the front and rear ends of the pipe filter is monitored in real time, and the upper limit of the differential
pressure alarm is set to realize the early warning of filter blockage.
 

Product Details

The micro-differential pressure transmitter HPT710 adopts silicon MEMS micro-pressure chip, after temperature
compensation, linear compensation, signal amplification, V/I conversion and other signal processing, it outputs
industrial standard 4mA~20mA, RS485 and other signals. With the functions of anti-surge, reverse polarity protection
and others, its product reliability is increased. Using temperature compensation and digital calibration, the temperature
drift performance and product stability are improved. This product is suitable for the pressure or differential pressure
measurement of various dry and non-corrosive gases.
