PDT Dewpoint Transmitter
A highly efficient and economical solution designed for trace moisture measurement in gases and dry compressed air, particularly suited for applications requiring monitoring of higher, ‘wetter’ dewpoints.
The PDT Dewpoint Transmitter offers a practical approach to continuous dewpoint measurement, catering for diverse requirements down to -60 °C dewpoint and available with three specific dewpoint ranges: -60 °C to +20 °C, -40 °C to +30 °C and -20 °C to +50 °C.
The compact 2-wire, 4-20 mA loop-powered transmitter features a bulk polymer sensing element — delivering excellent accuracy, stability and response speed across various dewpoint ranges. It is engineered to withstand pressures up to 5,000 kPa (50 barg), ensuring robust performance under demanding conditions. It offers IP65/NEMA 4 protection and for enhanced safety and reliability, the electrical connections are made via a durable M12 industrial connector.
