Promet Eexd utilizes Ceramic Moisture sensor technology.

The State-of-the-art thick- and thin-film semiconductor technology produces an exceedingly durable sensor, with superior measurement sensitivity to 10 ppbV moisture content and high-pressure capability up to 45 MPa (6526.7 psi).

Unlike older aluminium-oxide technologies, the inherent immunity to pressure shock of the Ceramic Sensor completely avoids any risk of sensor failure at commissioning or shutdown, whilst the unique inert nature of the sensor gives unrivalled long-term resistance to chemical attack, even in extremely sour gas with percentage level H2S concentrations. The microprocessor electronics unit in the sensor stores the sensor calibration data and provides a stable linear 4-20 mA output over the wide dynamic °C/°F dew-point range
