Rugged I.S dew point transmitter with ATEX certification from Michell Instruments

Michell Instruments has added to its range of Easidew dew-point transmitters with the Easidew PRO I.S., a rugged, intrinsically safe transmitter suitable for use in the natural gas, petrochemical and process industries where a rugged transmitter is required.

A natural progression from the Easidew TX I.S., the Easidew PRO I.S. is certified by ATEX for use in hazardous area zone 0, as well as for use with galvanic isolators.

Like the other transmitters in the Easidew Range, the Easidew PRO I.S. is part of the Sensor Calibration Exchange Programme – enabling customers to maintain traceability through periodic recalibration while keeping the process in operation. Signing up to the programme means that customers can order a new sensor, install it and then send back the old one to Michell for recalibration at a fraction of the cost of completely replacing the sensor – with the added benefit of no down-time.

The key to the success of the exchange programme is the innovative Easidew sensor technology. All the calibration data is stored within the transmitter’s flash memory and so calibration exchange, or service, can be affected in seconds, even by untrained personnel. The Easidew PRO I.S. is simply disconnected, removed from its sampling block and replaced by a new fully calibrated unit.

The Sensor Calibration Exchange Program for Easidew PRO I.S. makes it the perfect choice for measurement of dew point or moisture content in all hazardous area applications where a calibration traceability of the used equipment is crucial. Specific applications include CNG (compressed natural gas) dryers, hydrogen coolant in power generators, industrial gas manufacture and supply and many more.
