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.
