ACI ENT-TRANS 4-20 mA Enthalpy Transmitter


Previous Page

The A/ENT-TRAN is a low cost Enthalpy transmitter that converts a resistive type humidity sensor into a linear 2-wire, 4 to 20 mA output signal proportional to a scale of 0 to 50 BTU's.

The Advanced Ceramic Technology overcomes the limitations of other resistance-based humidity sensors that utilize water-soluble polymer coatings. This technology enables these sensors to fully recover from condensation and enables the sensor to maintain its accuracy over time. Despite its accuracy, the Advanced Ceramic Technology sensor and related circuitry is economical.

Each A/ENT-TRAN is calibrated at 3 different points, using an NIST Traceable temperature and humidity controlled environmental chamber. Factory selectable calibration can be achieved for elevations of 0, 1000, 2000, 3000, 4000, 6000, 8000, and 10000 feet. Reverse Action makes the slope negative, from 20 down to 4 mA.

 All of the A/ENT-TRAN Enthalpy Transmitters come with a five year factory warranty
