The working principle of the micro-differential pressure controller is that the measured pressure directly acts on the diaphragm of the sensor to make the diaphragm produce a micro-displacement proportional to the wind pressure.
So that the sensor capacitance changes, and the electronic circuit to detect this change, and convert the output of a corresponding standard pressure measurement signal.
Applications: SW-BO3 differential pressure sensors involved in clean technology, fire ventilation, test and measurement industry applications, it has become an indispensable core device for such products.
Starwin use the high-quality sensors, precision amplification lines, strict production technology, improve the test and aging test equipment to ensure that the production of sensors with excellent product quality. Pressure sensor according to different occasions generally can be divided into:
anterior chamber pressure sensor, gas pressure sensor, pressure sensor, indoor and outdoor pressure sensor, pressure sensor, filter pressure sensor.
