Dew Point Transmitter Model HDT

Xentaur’s Dew Point Meter, Model HDT, is a rugged and unique loop powered dew point meter capable of both gas and liquid hydrocarbon phase measurements.


Xentaur HDT
The Model HDT Dew Point Meter uses a Xentaur HTF™ high capacitance aluminum oxide sensor with a measuring range of -100ºC to +20ºF or -60ºC to +20ºC. Customers can also request special ranges for special applications. The Xentaur 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 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 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 provides accurate dewpoint measurements over its full range even under extreme temperature conditions, such as when installed outdoor or close to heat sources.
