Product Description

Holykell High Precision 100 PA Differential Pressure Transmitter for HVAC System

Through the connection of the air pressure transmitter and the control instrument, the differential pressureat the front and rear ends of the pipe filter is monitored in real time, and the upper limit of the differentialpressure 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 temperaturecompensation, linear compensation, signal amplification, V/I conversion and other signal processing, it outputsindustrial standard 4mA~20mA, RS485 and other signals. With the functions of anti-surge, reverse polarity protectionand others, its product reliability is increased. Using temperature compensation and digital calibration, the temperaturedrift performance and product stability are improved. This product is suitable for the pressure or differential pressuremeasurement of various dry and non-corrosive gases.
