XDT Series EX

Explosion Proof Digital Dew Point Transmitter

Our COSA XENTAUR™ Explosion Proof XDT EX™ Series Digital Dew Point Transmitter is in explosion proof enclosure, is UL approved for use in Hazardous Locations Class I Division 1 Groups B, C & D.

The Explosion Proof XDT EX 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 EX Series Digital Dew Point Transmitter takes 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.

Explosion-proof design: Designed to be explosion-proof, making it suitable for use in hazardous environments where there is a risk of explosion.
Highly accurate: Provides highly accurate measurements of dew point temperature, 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.

SPANCHECK CAPABLE IN THE FIELD

The XDT Series EX 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.

Programmable Alarm Relays

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.

User Friendly Interface

The dew point meter is operated through a menu driven user interface consisting of a custom LCD display with backlight, and four push buttons. The push buttons can be used to display several different engineering units which can be dew point in ºC, ºF, ppmv, g H2O/M3, lbs H2O/million scf.

ALUMINUM OXIDE SENSOR

The HTF™ aluminum oxide sensor is the product of years of intensive research and has been thoroughly field proven and performs better than other aluminum oxide moisture sensors on the market. HTF aluminum oxide sensors are manufactured with high uniformity. Consequently, sensors are freely interchangeable without factory calibration or changing of EPROMS, as is required with conventional aluminum oxide sensors.
