Description
The EMR3201001 sensing element uses a robust long life ceramic fulcrum lever technology / NTC / HIH4000 technology with the patented self-calibration system to guarantee the long-term stability and high performance differential pressure, temperature and humidity measurement. The ceramic fulcrum lever technology / NTC / HIH4000 sensor element used in the EMR3201001 is not affected by any condensation, high humidity or contaminants present in the measure environment.
The EMR3201001 has built-in electronic circuit, which enables digital measurement of differential 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 many domestic and light industrial applications including office, restaurants, classroom, and supermarket.
