The COSA Xentaur HDT Series Dew Point Meter is a rugged and unique loop powered dew point meter capable of accurate and reliable gas and liquid hydrocarbon phase measurements.
The HDT Dew Point Meter uses a COSA Xentaur HTF™ high capacitance aluminum oxide sensor with a measuring range of -100ºC to +30ºC or -60ºC to +30ºC.
Customers can also request special ranges for special applications. Our dew point sensors provide a high degree of accuracy, speed, of response and stability unavailable from instruments using conventional aluminum oxide or polymer sensors.

Our dew point sensors provide a high degree of accuracy, speed, of response and stability unavailable from instruments using conventional aluminum oxide or polymer sensors.
HART- Compliant Dew Point Transmitter
The HDT Series is a HART compliant dewpoint transmitter, providing loop powered analog as well as a digital output. Housed in a 32mm dia. Stainless steel housing it has an overall length of 136mm including the Industrial Standard 9.4mm 4-pin connector.
Measurement Accuracy & Stability
The HDT Series transmitter uses a multipoint calibration table which provides temperature compensated dewpoint readings for temperatures from -10ºC to +70ºC with the option of going below -10ºC. Thus, the HDT Series provides accurate dewpoint measurements over its full range even under extreme temperature conditions, such as when installed outdoor or close to heat sources.
