General The digital dewpoint transmitters are designed as compact, simple and reliable instruments, which will continually monitor air dryer performance, compressed air quality and dry gas moisture, from ambient dewpoint levels to as low as -100°C (-148°C). Applications Dewpoint transmitters are used wherever the dewpoint in a gas is critical. Applications include: monitoring and control of air dryers, plastic dryers, welding and laser gases, petrochemical feedstock gases, natural gas, clean rooms, glove boxes, transformer and switch gear insulation gases, cryogenic gases, heat treating...

SpanCheck in the Field This field calibration procedure is fully automated and the user is prompted through a simple one minute procedure, which requires no additional equipment. Error Indication The instrument has indication for sensor open, short or electronic system failure, which can activate any of the alarm relays. NIST / NPL Traceability Option Certificates for NIST and NPL traceability are available upon request. Instruments can be recertified periodically at Xentaur’s laboratories. Same Transmitter – Multiple Configurations Model XDT-OEM™ is a stand alone board suitable for...

The HTF™ Aluminum Oxide sensor is the product of years of intensive research and has been thoroughly field proven. HTF technology offers significant performance advantages over all other aluminum oxide moisture sensors. High Capacitance Response Due to a hyper-thin film and a special pore geometry, sensors have a capacitance change over their full range, several orders of magnitude larger than that of conventional aluminum oxide sensors. Additionally, this change is quasi linear and its sensitivity to temperature is negligible. The advantages of a linear high capacitance response are:...
