Enhanced Loop Powered Transmitter now Intrinsically Safe

Michell Instruments are delighted to announce they have developed a certified intrinsically safe version of their Easidew Transmitter. The Easidew TX I.S. increases the already highly successful range of Easidew dew point instruments, which includes portable and on-line hygrometers, as well as dew point transmitters. The Easidew TX I.S. is a low cost, rugged impedance dew-point transmitter for continuous measurement in industrial gas applications.

The Easidew TX I.S. is ATEX certified by BASEEFA for use in hazardous areas to Ex II 1G ia IIC T4 when used with a galvanic isolator for signal power supply connections. Easidew TX I.S. can therefore be safely used in virtually all industrial gas measurement applications. The certification lists five different galvanic isolators from two different manufacturers. This allows the customer to choose the most suitable isolator to the correct hazardous / safe area interconnection.

The new transmitter offers the customer many more new and improved features. The modified transmitter 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 intrinsically safe transmitter has powerful processing capability allowing for the first time the on-board calculation of ppm(v) moisture content (ranges 0-100, 0-1000ppm and 0-3000ppm). Application software also allows the user to configure output parameters, ranges and scaling.

The Easidew TX I.S. is designed for ease of use, incorporating all the features the user could want to make installation and operation as simple as possible. For the first time, dew point measurement is made as accessible as temperature and pressure with this fully configured, calibrated transmitter that can be instantly incorporated into your air or gas management and control system.

The key to the Easidew TX I.S. Transmitter’s performance is its 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.

Aside from all of the new features the Easidew TX I.S. transmitter offers, it is also economical to purchase, install and operate. Installation costs are minimal because of the transmitters ruggedness and simplicity. On-going operating costs are low because of the transmitters stability and reliability. Only periodic re-certification is required to maintain traceability. Michell will even organise an exchange programme for the customer so that the process is never out of operation.

All of the above makes the Easidew TX I.S. the perfect choice for measurement of dewpoint or moisture content. Specific applications include CNG (compressed natural gas) dryers, hydrogen coolant in power generators and industrial gas manufacture & supply.
