Description
The EPDAF sensing element uses a robust long life ceramic fulcrum lever technology with the patented self-calibration system to guarantee the long-term stability and high performance pressure measurement. The sensor element used in the EPDAF is not affected by any condensation, high humidity or contaminants present in the measure environment.
The EPDAF has built-in electronic circuit, which enables digital measurement of pressure value with temperature compensation logic by continuous monitoring of the sampling air. Built-in calibration routine is integrated in the transmitter electronic circuit. It is ideal for measuring air flow in air condition system, staircase pressurization, lift lobby pressurization and measuring of low air flow in clean room, laboratory, operating theater and isolation room application.
