4-20mA Wind Micro Differential Pressure Transmitter/Transducer for HAVC

Product Discription

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.
