Cermet II IS Continuous Dewpoint Meter is any easy to install self-contained hygrometer system for measurement of the moisture content of flammable and non-flammable gases within hazardous areas. This continuous dewpoint meter comprises an intrinsically safe transmitter, Transmet IS, and a safe area Cermet II IS Control Unit.
Housed in a stainless steel case, the Transmet IS transmitter offers ingress protection to IP66 (NEMA 4). The Cermet II IS Continuous Dewpoint Meter Control Unit is a 19" sub rack unit containing display, transmitter power supply and isolation barriers suitable for location in a designated safe area. This continuous dewpoint meter provides all necessary user interfacing, including multi-unit display, alarms, analogue and digital outputs. Control unit and transmitter are connected by up to 500 metres of cable via galvanic isolation barriers.
A hygrometer must operate reliably over it's total operating range, in the user's demanding operational environment. The Transmet IS transmitter has been designed to copy with extreme industrial conditions and is resistant to shock, vibration and extremes of temperature and operating pressure.
Furthermore, the advanced design of the Michell Ceramic Moisture Sensor, coupled with extremely competent measurement circuitry, gives Cermet II IS Continuous Dewpoint Meter a class leading accuracy, repeatability and measurement range at pressures up to 30 MPa.
