Michell Instruments DT722 series RH and temperature transmitters

Maintaining reliable 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.

To meet specific application needs, the series is available in digital (DT722) and analog (DT722-X18) models. The digital electronic platform version gives high-performance measurement with good RH accuracy and delivers consistent and accurate results even over changing ambient conditions.

The DT722-X18 is an analog through path measurement device with sound mechanical toughness. Field adjustment is quick and easy, making it suitable for use in all types of aftermarket service and the nuclear industry. The device offers quick and simple serviceability and high stability.

The transmitters have been designed for use in severe industrial environments. They are reliable and robust, with strong, 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 to afford protection to the sensors based on specific environmental conditions.
