Maintaining reliable RH measurements in harsh or corrosive environments is notoriously difficult as the conditions themselves degrade the sensors and equipment, often in short tim periods. To provide a solution to this problem, Michell Instruments has released the DT722 RH and temperature transmitter.

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

The DT722-X18 is an analog through-path measurement device with high mechanical toughness. Field adjustment is quick and easy, making it a good choice for use in all types of aftermarket service and it is already in service in the nuclear industry.

The transmitters have been designed for use in severe industrial environments. They offer a strong, stainless steel housing providing protection against rough handling or accidental damage, IP65 (NEMA 4) ingress protection, and a probe that can withstand temperatures up to 150°C.

The transmitters are for duct mounting in the most suitable place for the application. They have high chemical resistance for longer use in contaminated areas and are available with a selection of filter materials to afford best protection to the sensors based on specific environmental conditions.
