Measurement Technology<\/strong><\/h3>\n

The Michell Ceramic Moisture Sensor is a proprietary metal-oxide film impedance sensor<\/strong> developed by Michell Instruments (UK), representing the most advanced generation of capacitive\/impedance dew-point sensors. Derived from early aluminium oxide sensors of the 1950s, the current ceramic design provides superior robustness, stability, and accuracy<\/strong> under demanding industrial conditions.<\/p>\n

The sensor consists of a metallised ceramic structure<\/strong>, produced using thick- and thin-film techniques on a semiconductor-grade ceramic base. Functioning as a moisture-sensitive capacitor<\/strong>, water vapor permeates a conductive layer (gold-coated) into a hygroscopic dielectric beneath, causing changes in sensor impedance<\/strong> proportional to moisture content. These impedance changes are converted by the transmitter electronics into precise dew-point measurements, calibrated and traceable to NPL (UK) and NIST (USA)<\/strong> standards.<\/p>\n

Unlike conventional aluminium oxide sensors, Michell Ceramic Sensors are resistant to zero-shift, memory effects, and drift<\/strong>, even under aggressive gases<\/strong> such as sour natural gas with high H\u2082S content and pressures up to 300\u202fbarg. This enables direct dew-point measurement at pipeline\/process pressures<\/strong>, with exceptional long-term stability and reliability. In applications requiring moisture content units, combining the sensor with monitoring systems (e.g., Promet I.S.) provides accurate conversion to ppmV, mg\/m\u00b3, or lb\/MMSCF<\/strong>, with dynamic pressure compensation if needed.<\/p>\n
