Dew Point Sensor Calibration Exchange Program for New Transmitter

Jul 13 2009

Michell Instruments (UK) are delighted to announce they have extended their successful Sensor Calibration Exchange Program to the recently introduced Easidew TX I.S. Dew Point Transmitter.

The key to the Michell’s Calibration Exchange Program is the innovative Easidew sensor technology. Michell Instruments’ Advanced Ceramic Moisture Sensor is coupled with advanced microprocessor based measurement circuitry to produce a fully calibrated and interchangeable sensor transmitter. All 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 TX I.S. is simply disconnected, removed from its sampling block and replaced by a new fully calibrated unit. When periodic re-certification is required to maintain traceability. Michell will organise an individual exchange programme for the customer, so that the process is never out of operation. The Easidew TX I.S. series is designed for ease of use, incorporating all the features the user could want to make installation and operation as simple as possible. Installation costs are minimal because of the transmitter’s ruggedness and simplicity. On-going operating costs are low because of the transmitter’s stability and reliability. For the first time, dew point measurement is made as accessible as temperature and pressure with this fully configured and calibrated transmitter that can be instantly incorporated into an air or gas management and control system. The Easidew TX I.S. is certified by ATEX, CSA and FM Approvals for use in hazardous areas. It can be safely used in virtually all industrial gas measurement applications. The certification lists seven different galvanic isolators. This allows the customer to choose the most suitable isolator to the correct hazardous / safe area interconnection. The new transmitter offers more new and improved features. It can now be connected in a 2-Wire loop powered or 3-Wire configuration. The Easidew TX I.S. also features HDPE filter, designed to show contamination for service ease which is <10um porosity and impermeable to liquids. The Sensor Calibration Exchange Program for Easidew TX 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.
