Dew point transmitter is IS for CNG applications
The new Easidew TX transmitter is a small and reliable intrinsically safe dew point transmitter, recently developed by Michell for CNG applications
The Easidew TX IS is a low cost, rugged impedance dew-point transmitter for continuous measurement in industrial gas applications.
The Easidew TX IS 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 IS can therefore be safely used in virtually all industrial gas measurement applications.

Increased accuracy in cooled mirror instruments
Michell Instruments has developed a new technology to increase the accuracy and reliability of their Optidew Cooled Mirror Hygrometer instruments, the Frost Assurance System Technology (FAST)
'Optidew' cooled mirror dew-point applications
The Optidew cooled mirror dew-point meter offered by Michell Instruments can now be used for a wide variety of applications due to its increased cable length of up to 250 metres
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 IS also features an HDPE filter, designed to show contamination for service ease which has less than 10micron porosity and is 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 IS 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 IS transmitter performance is its sensor technology.
The 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 flash memory and so calibration exchange, or service, can be affected in seconds, even by untrained personnel.
The Easidew TX IS 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 IS transmitter offers, it is also economical to purchase, install and operate.
Installation costs are minimal because of the transmitter ruggedness and simplicity.
On-going operating costs are low because of the transmitter 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 IS 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 and supply.
