Michell have made multiple process moisture measurements easier with their Multi-Channel Control Unit (MCU). The Promet I.S, process moisture in gas analyzer, is now available in a multi-channel format, with the MCU. This enables up to four measurement channels within a single 19” sub-rack unit. The channels can be combined together with a sister product for moisture in liquid measurement – the Liquidew I.S – into the MCU 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 MCU is very simple to operate: its bright alphanumeric LED display, with optional live pressure compensation, provides unit conversions from dew point to an exhaustively wide range of alternative moisture content units to allow the user complete flexibility to select their preferred unit of measurement. The MCU is easy to install into existing sampling and distribution systems with minimal wiring. To allow for further expansion, customers can order 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 I.S can measure dew points as low as -100°C, and is calibrated and traceable to NPL and NIST. Edited by Constanze Schmitz
