Apdtc Series 01

Description

The ADPTC 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 ADPTC is not affected by any condensation, high humidity or contaminants present in the measure environment. The ADPTC 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 differential pressures in air condition system, staircase pressurization, lift lobby pressurization and measuring of low pressure in clean room, laboratory, operating theater and isolation room application.
