Finally permanently trouble-free

IPF offers a range of dew point sensors for compressed air systems.

Compressed air is indispensable in many industrial sectors. Depending on the application, different requirements are placed on the medium. However, they all have one thing in common: maintaining a specific moisture content or dew point of the compressed air is a basic prerequisite for long-term, trouble-free operation, which, among other things, ensures greater energy efficiency and sustainable cost savings.

Condensation in compressed air lines is a recurring cause that rapidly shortens the service life of pneumatic components. For example, hoses become brittle more quickly or metal components corrode, to name just a few examples. In certain processes, moisture also leads to the sticking of various goods transported by compressed air, such as sugar, flour, cement, granules, etc.

IPF has added the YT900001 sensors for absorption dryers and the YT900002 sensors for refrigeration dryers to its product range specifically for humidity and dew point measurement in compressed air and gases. Relative humidity is measured using a capacitive polymer sensor. Only water vapor penetrates the cover electrode by diffusion and reversibly attaches to the polymer, changing the sensor's capacitance. The sensor element impresses with its high long-term stability (>5 years) and high accuracy (±1 °C at 50…-20 °C, ±2 °C at -20…-50 °C, ±3 °C at -50…-80 °C).

The sensors are designed for two measuring temperature ranges: -80 °C…+20 °C (YT900001) and -20 °C…+50 °C (YT900002). The measured values can be output either via an analog output (4…20 mA) or a Modbus RTU interface. The AT000009 measuring chamber is available for quick and easy installation. The connection is made via a 5-pin connector (e.g. VK505621).
