XDT Series

Reliable Digital Dew Point Transmitter

Our 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.

SpanCheck Capable in the Field

The HDT Series has SpanCheck™. This field calibration procedure is fully automated, and the user is prompted through a simple one-minute procedure, which requires no additional equipment.

Ensures accuracy: Allows users to quickly and easily check the accuracy of the instrument in the field, without the need for additional equipment or specialized skills. This helps ensure that the instrument is providing accurate and reliable measurements, which is crucial in many industrial and commercial applications.
Saves time and money: Eliminates the need to send the instrument back to the manufacturer or a calibration lab for periodic calibration checks, which can be time-consuming and costly. Instead, users can perform a quick and simple calibration check in the field, reducing downtime and saving money.
Increases productivity: Allows users to check the calibration of the instrument on-site, without the need for additional equipment or specialized skills. This helps increase productivity and efficiency, as users can quickly verify the accuracy of the instrument and continue with their work.
Reduces risk: Helps reduce the risk of inaccurate measurements, which can lead to costly errors or safety hazards in certain applications. By allowing users to easily verify the calibration of the instrument in the field, Spancheck helps ensure that the instrument is providing accurate and reliable measurements at all times.

Some of the industries that use the XDT Series digital dew point transmitters are:

Natural Gas: Used in natural gas processing and transportation to ensure that the gas meets the required dew point specifications. Accurate measurement of dew point temperature is essential to prevent the formation of hydrates and ensure safe and efficient gas transport.
Power Generation: Monitor the moisture content of the fuel gases and control the humidity of the air used in combustion. The XDT™ series helps to improve the efficiency of power generation and reduce the formation of pollutants.
Petrochemical: Monitor the moisture content of various gases and liquids, such as ethylene and propylene. Accurate measurement of dew point temperature helps to prevent corrosion and ensure the quality of the final product.
Pharmaceutical: Monitor the humidity and dew point temperature in clean rooms and other critical environments. Accurate control of humidity helps to maintain product quality and prevent contamination.
Food and Beverage: Monitor and control the humidity of the processing environment, which is essential for product quality and safety.
