Product Description

Macsensor DP825 micro differential pressure transmitter adopts silicon MEMS micro pressure chip. With temperature compensation,
digital calibration, linear compensation, signal amplification, V/I conversion and other signal processing, temperature drift performance
and product stability has been improved. In addition, anti-surge, reverse polarity protection and other features improve product reliability.
It is suitable for various dry non-corrosive gas pressure or differential pressure measurement, widely used in HVAC pipelines, pipeline flow
rate tests, clean workshops, building automatic control and other fields.

Indoor and outdoor differential pressure monitoring
Through the connection between the air pressure transmitter and the control instrument, when the indoor and outdoor differential pressure reaches the preset upper limit, the fan is started to decompress, and when the differential pressure reaches the preset lower limit, the fan is turned off.

Anti-clogging filter
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.
