HDT-LQ Series

Reliable Dew Point Aluminum Oxide Transmitter

Real value and fits wide range of applications – loop-powered Aluminum Oxide Sensor Dew Point Transmitter

Based on years of dedicated research and development and proprietary scientific breakthroughs, our COSA XENTAUR™ HDT-LQ™ Series combines our Dew Point Transmitter HDT™ Series with the HTF™ aluminum oxide sensor.  Our HDT-LQ Series 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 dewpoint levels to as low as -100°C.

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

The HDT-LQ Series is a high-precision dew point transmitter designed for low moisture applications. Here are some of the advantages of the HDT-LQ Series:

  • High accuracy: Provides highly accurate measurements of dew point temperature, with an accuracy of up to ±0.1°C.
  • Low moisture detection: Specifically designed for low moisture applications, making it suitable for use in environments where even trace amounts of moisture can be a problem.
  • Fast response time: Provides real-time measurements, with a response time of less than 5 minutes.
  • 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 low moisture applications.
  • Stable and reliable: Built to be stable and reliable, with a low-drift sensor and advanced signal processing technology.
  • User-friendly: Designed to be easy to use, with a clear and intuitive display and simple one-button operation.
  • Flexible installation: Can be installed in a variety of configurations, including direct insertion, flow-through, and sample conditioning systems.
  • Low maintenance: Requires minimal maintenance and calibration, reducing downtime and costs.

Aluminum oxide sensors are used in the HDT-LQ Series, as they offer several advantages for dew point measurement, including high accuracy, stability, and resistance to contamination. 

The HDT-LQ Series Dew Point Transmitter is typically used in industries where the measurement of dew point or moisture content in gases is critical for the process or product quality. Some of the industries that use this type of transmitter include:

  1. Natural Gas: Dew point measurement is important in the natural gas industry to prevent hydrate formation, which can cause blockages in pipelines and damage equipment.

  2. Petrochemical: Dew point measurement is critical in the petrochemical industry to ensure that moisture does not contaminate the final product, which can affect product quality and safety.

  3. Semiconductor: In the semiconductor industry, dew point measurement is important to prevent moisture from damaging sensitive electronic components during the manufacturing process.

  4. HVAC: The HVAC industry uses dew point measurement to control the humidity level in buildings, which can affect indoor air quality and occupant comfort.

  5. Pharmaceutical: The pharmaceutical industry uses dew point measurement to control the moisture content in the manufacturing process, which can affect the stability and shelf-life of the final product.

SPANCHECK CAPABLE IN THE FIELD

The HDT-LQ 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.
