Promet analysers - .PDF file.

Michell has released the Multi-Channel Control Unit (MCU), a new Promet IS process analyzer that enable up to four measurement channels, in a single 19in sub-rack unit, for measuring moisture in gas.

The MCU allows Promet IS channels to be combined together with the Liquidew IS, a sister product for moisture in liquid measurement, to enable both gas and liquid sample measurements to be taken with a single analyzer system.

Each channel of the MCU functions independently of the others so that maintenance can be carried out on one channel while the others continue to operate as normal.

The device’s bright alphanumeric LED display, with optional live pressure compensation, provides unit conversions from dew point to a wide range of alternative moisture content units so that the user may select their preferred unit of measurement.

It is simple to install into existing sampling and distribution systems with minimal wiring.

Customers wanting to expand the system further can order extra blank channels.

The front panel interface enables the user to scroll through the set-up menus to easily configure the analyzer to their own requirements.

Four user-adjustable alarm points and two analogue 4-20mA outputs are provided, as well as a digital RS485 RTU for connection to external devices.

Based on Michell’s Ceramic Moisture Sensor, the Promet IS can measure dew points as low as -100C, and is calibrated and traceable to NPL and NIST.

Michell Instruments

Michell Instruments is an international leader in high-precision sensing with over 35 years’ experience in the field, specialising in instrumentation for dew point, relative humidity and oxygen analysis. The company serves industries as diverse as petrochemical and pharmaceutical to power generation and food processing. The product range includes:

  • High-precision ceramic moisture sensors to measure trace moisture in process applications.
  • Relative humidity transmitters and sensors for use in HVAC applications, pharmaceutical storage and other production processes where controlled environmental conditions are crucial.
  • Humidity calibration systems and reference dew-point hygrometers enable customers to carry out the calibration of portable hygrometers and relative humidity instruments in-house, saving on downtime and costs.
  • Zirconia and thermo-paramagetic oxygen analysers for combustion optimisation, maintaining gas purity, controlling levels of CO2 in breweries and many other applications.
  • Condumax II Hydrocarbon dew point analysers ensure the quality of natural gas at custody transfer, prevent gas burner failure and the prolong the life of process equipment, helping companies save millions of dollars on repairs and downtime.
  • Trace moisture in hydrocarbon liquids analysers are available in explosion-proof and instrinsically safe versions and allow the continuous measurement of moisture content in a wide range of applications from transformer oil, petrochemical factions and pure hydrocarbons.
  • Process moisture analysers provide continuous on-line measurements of trace moisture in process gases and are available as explosion-proof, instrinsically safe and laboratory versions.

Michell Instruments has three manufacturing locations: Oosterhout, The Netherlands; Lyon, France and Ely, UK. The company has an extensive network of factory-trained application engineers, subsidiaries and distributors stretching across 56 countries.
