Our differential pressure sensors are built using time-tested capacitive technology. Capacitive pressure sensors have a thin diaphragm that flexes as pressure is applied, and the distance of this flex is measured and translated as a pressure reading. This superior technology allows our pressure sensors to report in near real-time with extraordinary accuracy.
Differential pressure measurement is important in the context of HVAC systems largely for efficiency. In a general building setting, maintaining differential pressure ensure enough airflow to condition the building, while not overworking the system - preventing unnecessary energy usage. Measuring the pressure differential across filters in HVAC ductwork, for example, also helps with preventative maintenance - reducing both short term and long term costs.
Our broad selection of DP sensors offer customers a variety of pressure ranges, electrical terminations, port connections, accuracy ranges and with/without integrated LCD displays.
