Heating, ventilation and air conditioning (HVAC) and adding
refrigeration (HVAC/R) is the technology controlling thermal
comfort and air quality for indoor structure and vehicles. HVAC is
plays an important role regulating temperature and humidity for a
variety of residential structures, such as single family homes,
apartment buildings, hotels, office buildings, etc.
The differential pressure air velocity transmitter plays an
important role in HVAC application-duct exhaust. The principle is
that when the pressure acts on the diaphragm of the sensor, the
diaphragm produces a micro-displacement that is proportional to the
pressure of the medium, changes the resistance of the wind pressure
sensor, and detects this change with the electronic circuit, and
converts an output corresponding to this Standard signal of
pressure.
WNK268 intelligent pressure transmitter is assembled with aluminum
housing and stress isolation technology. Integrated structure
design lead to compact layout. With intelligent compensation
technology, it is suitable for wind pressure, wind speed & flow
measurement.
