LPDT2 SERIES
Dew Point Transmitter with Aluminum Oxide Sensor
Ultra-Compact DEW POINT Transmitter

Our NEW COSA XENTAUR™ LPDT2™ Series Low Pressure Dew Point Transmitter is ultra-compact, and loop-powered (two-wire). It comes with or without a display. LPDT2 Series Low Pressure Dew Point Transmitter with display is a fully functional instrument operated through a miniature custom LCD display and four push buttons, using the same user-friendly interface as all our hygrometers. Where a display at the point of measurement is not necessary, the LPDT2 is the answer. Modbus, and Analog outputs provide a simple and cost-efficient solution with trusted results.
Our LPDT2 Series Low Pressure Dew Point Transmitter is a highly accurate and reliable instrument designed for measuring dew point temperature in industrial applications. The LPDT2 uses a thin-film aluminum oxide sensor to provide accurate and stable measurements of dew point temperature, which is a key indicator of moisture content.
Some key features of our LPDT2 Series Low Pressure Dew Point Transmitter:
- High accuracy: Designed to provide highly accurate measurements of dew point.
- Wide measuring range: Can measure dew points from as low as -148°F (-100°C) to as high as 68°F (20°C), making it suitable for a wide range of industrial applications.
- Fast response time: Provides quick and real-time measurements, which is crucial for process control and optimization.
- Stable and reliable: The aluminum oxide sensor used in the LPDT2 is highly stable and reliable, with a long lifespan and low maintenance requirements.
- Resistant to contamination: The aluminum oxide sensor is highly resistant to contamination from oils, fuels, and other substances that can interfere with measurements.
- User-friendly: Designed to be user-friendly, with an intuitive interface and easy installation and calibration.
- Versatile: Can be used to measure the moisture content of various gases and liquids, including natural gas, compressed air, hydrogen, nitrogen, and more.
