HDT Series

Dew Point Aluminum Oxide Sensor

Reliable Dew Point 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™ Hyper-Thin-Film Technology Series dew point transmitter uses our HTF™ aluminum oxide sensor. Our HDT 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 HDT Series dew point transmitter is a rugged and unique loop powered dew point meter capable of accurate and reliable gas and liquid hydrocarbon phase measurements. It has a measuring range of -100°C to +20°C.

Customers can also request special ranges for special applications. Our dew point sensors provide a high degree of accuracy, speed, of response and stability unavailable from instruments using conventional aluminum oxide sensors.

Our HDT Series dew point transmitter is a state-of-the-art instrument designed to accurately measure the dew point or moisture content in gases. The instrument utilizes advanced technologies such as a ceramic sensor, a thin-film aluminum oxide sensor, and a thermal conductivity sensor to provide precise and reliable measurements.

The HDT Series dew point transmitter is available in two versions, the HDT-L and HDT-K. The HDT-L version is designed for low dew point applications, while the HDT-K version is designed for high dew point applications.

The transmitter features a user-friendly interface with a large graphical display that provides real-time measurement data, including dew point temperature, pressure, and humidity. The HDT Series transmitter can be configured to output data in various formats, including analog signals, digital communication protocols, and alarm signals.

The HDT Series dew point transmitter is designed to operate in harsh industrial environments, with a rugged construction that can withstand extreme temperatures, humidity, and vibration. The transmitter is also equipped with a self-diagnostic feature that alerts the user to any potential issues, allowing for proactive maintenance and troubleshooting.
