COSA XENTAUR™ XDT™ Series digital dew point 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 dew point levels to as low as -100ºC (-148ºF) up to +20ºC (+68ºF).

The XDT Series transmitter take full advantage of state-of-the-art microprocessor technology and offer many advanced intelligent features. With optional dual alarms, analog and digital outputs, our dewpoint transmitters can be used as indicators, alarm units or controllers.

Our XDT Series digital dew point transmitters are highly accurate and reliable instruments that provide continuous monitoring and measurement of dew point temperature in various industrial and commercial applications. Here are some of the benefits of the XDT Series:

High accuracy: Provides highly accurate dew point temperature measurements, with an accuracy of up to ±0.2°C.

Digital output: Provides digital output signals, such as RS485, Modbus, and HART, which can be easily integrated with other monitoring and control systems.

Wide measuring range: Can measure dew point temperatures from as low as -110°C to as high as 20°C, making it suitable for a wide range of applications.

Fast response time: Provides real-time measurements, with a response time of less than 5 minutes.

User-friendly: Designed to be easy to use, with a clear and intuitive display and simple one-button operation.

Versatile: Can be used to measure the moisture content of various gases and liquids, including natural gas, compressed air, hydrogen, nitrogen, and more.

Remote monitoring: Can be remotely monitored and controlled through the digital output signals, allowing users to monitor and control the instrument from a central location.

Durable: Built to withstand harsh industrial environments and has a long service life.

The two optional alarm relays can be independently programmed to switch at any dew point with variable hysteresis, which makes the transmitter ideally suited as an energy saving controller for desiccant dryers in “dew point demand” mode or safety cutoff in process control, high power laser, etc. The status of the relays is shown on the display with flashing “HI” or “LO” indicators while displaying the dew point.
