Product Description

The MCM Continuous Moisture Measuring System (CMMS) provides catalytic reforming applications with the most accurate and reliable means available for on-line monitoring of moisture in recycle gas. Utilising our unique Temperature Controlled Silicon Sensor, the CMMS detects changes as low as 1 ppm[V] and stands up to corrosives, such as chloride, ensuring representative sampling of the recycle gas stream.
MCM’s Temperature Controlled Silicon Sensor brings distinct benefits to catalytic reforming applications:
Silicon sensors have unique moisture capacitance behaviour, enabling accurate measurement of moisture measurement in recycle gas in the range 0 to 800 ppm[V].
The Silicon sensor is unaffected by chloride levels up to 150 ppm[V].
Silicon sensors can resist corrosive agents, such as HCl, that are commonly found in recycle gas. As a direct result, sensor life is measured in years, rather than months.
The unrivalled speed of response of a Silicon sensor means that, upon commissioning or after exposure to high moisture levels, the system requires only a short period of drydown to provide accurate data.
Automatic recalibration is accomplished daily, using three internally generated, prime moisture calibration standards. By using a newly calibrated Sensor every 24 hours, the MCM CMMS eliminates the potential for long-term drift and offers extreme accuracy, stability and repeatability
Product Specification
Sensor Type Silicon Sensor, Temperature Controlled to 46°C
Operating Ranges 1 to 1000 ppm[V], Ranges in Dewpoint °C / °F and lb/mmscf available upon request
Speed of Response Full scale 'wet' to 'dry' in <1 minute using Push Purge®.
ATEX Rating II 1G EEx ia IIC T4 Ta = -20°C to +60°C
Diagnostics Push Purge® feature aids sensor drydown, confirms that the senor and electronics are operational and highlights the presence of contamination. Push Purge® confirms if the speed of response of the analyser is maintained, validates readings on-line and removes hysteresis before each measurement.
