Product Description

Single channel Differential-Pressure Air Tightness Tester judge air tightness by measuring the differential pressure on both sides of the test object. They are generally equipped with a pressure sensor and a differential pressure sensor. The pressure sensor measures the static pressure on both sides of the test object, while the differential pressure sensor measures the pressure difference between the two sides. The instruments generally require calibration to ensure accurate measurement.

Principle: The differential pressure sensor can be piezoelectric or piezoresistive. It obtains the differential pressure value by measuring the force or deformation exerted by gas on the sensor.
