Humidity sensor LFS04
Measures moisture in gases
The LFS04 air humidity sensor measures the absolute humidity in gases from -80 °C frost point to +20 °C dew point – from trace humidity to high humidity. In industrial measurement technology, it is used for a large number of different gases and gas mixtures.

Technical information
The sensor is used in industrial measurement technology for the control, monitoring and quality assurance of gas or air treatment underwater applications. The air humidity sensor for trace moisture measurement in gases in a measuring range from -80 °C frost point to +20 °C dew point for extreme applications. Other ranges are also possible on request. It is a 4-20 mA transmitter for measuring absolute humidity in °C dew or frost point. Optionally in ppmW/ppmV in gases.
The measuring range of the sensor includes the range of high humidity as well as trace moisture. The integrated RS232 interface is used for data output and for configuring the sensor. The switching output of the sensor is also programmed via this access. The high media compatibility ensures a wide range of applications as an online measuring device for many gases and gas mixtures.
Due to the wide measuring range, the sensor is used for monitoring and controlling refrigeration and adsorption dryers. By using LFS04, the quality of air drying systems in manufacturing processes are secured and energy costs are saved during drying.

How is the product maintained?
We recommend an annual recalibration and adjustment for all our sensors to be able to guarantee the exact functionality. We calibrate our sensors with state-of-the-art measurement technology in our in-house calibration laboratory. Our test equipment is one of the most accurate references in measurement and control technology. The test results are summarised in a factory calibration certificate in accordance with DIN EN ISO/IEC 17025:2018-03.
