Suitable for continuous measurement of trace moisture in dry compressed air and industrial process gases, this dewpoint transmitter utilises the ultra high capacitance SHAW moisture sensing technology. Configurable to output a linear, isolated, 4-20 mA signal with a measurement accuracy of ±2 °C (±3.6 °F) dewpoint. The SDT-Ex incorporates advanced electronics and will not suffer any loss of signal when sited up to 1,000 metres (3,280 feet) away from its display.

Intrinsically safe dewpoint transmitter includes AutoCal functionality and open/short circuit detection.
