Michell Instruments DT722 RH and temperature transmitter

Maintaining reliable relative humidity (RH) measurements in harsh or corrosive environments is notoriously difficult as the conditions themselves degrade the sensors and equipment, often in short time-periods. Michell Instruments’ DT722 RH and temperature transmitter provides a solution to this problem.

The DT722 series is available in digital (DT722) and analog (DT722-X18) models. The digital electronic platform version provides good performance measurement with good RH accuracy and delivers reliable, consistent and accurate results even over changing ambient conditions. The analog through path measurement device has good mechanical toughness. Field adjustment is quick and easy, making it suitable for use in all types of aftermarket service and the nuclear industry. It also has quick and simple serviceability and high stability.

The transmitters have been designed for use in severe industrial environments. They are reliable and robust with a stainless steel housing providing protection against rough handling or accidental damage, IP65 (NEMA 4) ingress protection and a probe which can withstand temperatures up to 150°C. The transmitters are for duct mounting in the most suitable place for the application. They have good chemical resistance for longer use in contaminated areas and are available with a selection of filter materials.
