Dwyer Instruments Inc., a leading manufacturer in the controls and instrumentation industry, recently announced the release of its new Series RHL low cost humidity or humidity/temperature transmitter for commercial/HVAC applications.

According to the company’s press release, the ultra-fast Series RHL Transmitter provides a stable, repeatable, and accurate means of measuring humidity only or both temperature and humidity in the harshest of environments. The polymer capacitance sensor is not affected by condensation, fog, high humidity or contaminants, and the state-of-the-art sensor is designed for years of calibration-free service.

The Series RH/RHL is a two-wire transmitter with a 4-20 mA loop powered output. The humidity/temperature version provides dual 4-20 mA output signals with an accuracy of about 3% RH and about 0.9ºF @ 72ºF (0,3ºC @ 25ºC). An optional  2-line alpha-numeric LCD is available on humidity/temperature models with field selectable temperature units.
