RH-15xP-NA-xx-xx Series Duct Humidity Transmitter & Sensor

RH-15xP-NA-xx-xx Series Duct Humidity Transmitter & Sensors, convert a resistance to a linear 4 to 20 mA, 0 to 5, or 0 to 10 V DC output signal. The current transmitter may be transmitted over long distances on unshielded twisted pair wire and will not be affected by lead wire resistance or electrical noise. The Advanced Ceramic technology design overcomes the limitations of other resistance based humidity sensors that utilize water soluble polymer coatings. The Advanced Ceramic Technology enables these sensors to fully recover from condensation and allows the sensor to maintain its accuracy over a longer period of time. Despite its accuracy, the Advanced Ceramic Technology sensor and related circuitry is extremely economical.

The accuracy is maintained over the operating range using a thermistor for temperature compensation. Precision production tolerances maintain sensor interchangeability to within +/- 3%. Field calibration can be done by using the on board increment and decrement dip switches. Each toggle will allow for a +/- 0.5% RH increase or decrease. Calibration of the 4 to 20 mA transmitter can also be done using the zero and span adjustment potentiometers. Each RH transmitter is calibrated at three different points, using an NIST Traceable Temperature / Humidity Chamber. All of these units come with a five year warranty
