Dew point measurement and monitoring in compressed air systems is essential. Drying of granulate in plastics technology, the generation and usage of various technical gases (N2, O2, Ar, H2) and a lot more applications require professional dew point measurement equipment for perfect operation. Proven and reliable dew point meters from CS INSTRUMENTS are helping customers worldwide to ensure the required product quality in compressed air and gas systems.
As experience manufacturer of dew point sensors CS INSTRUMENTS offer a wide and field proven product portfolio for dew point sensors. Our delivery program includes especially designed stationary and mobile solutions for dew point monitoring of refrigeration, desiccant or membrane driers. Ideal accessories like measuring chambers, dry containers or diffusion tight hose ensure that CS dew point systems are the perfect solution for a trouble-free dew point measurement.
Standard interfaces are 4…20mA, Modbus RTU or M-Bus. Furthermore, all dew point sensors can be combined easily with our data loggers. Dew point sensors form CS INSTRUMENTS enables a reliable and long-term stable monitoring of the pressure dew point in industrial applications from -80 to +20 °C dew point. We recommend the indirect installation with measuring chamber. This enables easy mounting and dismounting of the probe without interruption of the line, a quick response time and optimum sensor protection.

Air always contains water in form of vapor. Since air contrary to water can be compressed the water drops out during the compression procedure in form of condensate. The maximum humidity of the air depends on the temperature and the volume. It does not depend on any quantity. The ambient air can be imagined like a wet sponge. In relaxed condition, it is able to absorb a certain quantity of water. It the sponge is squeezed water drops out. Some water will remain in the sponge even in case of a strong compression. This process is similar to the compressed air applications.
At each temperature, air or other gases can hold a maximum quantity of water. The warmer the air is the more water can be absorbed. Dew point is the temperature to which air or gas must be cooled for the water vapor in it to condense into dew or frost.
Pressure dew point is the temperature to which the compressed air can be cooled down without any condensation. The pressure dew point depends on the final compression pressure. In case of a declining pressure also the pressure dew point drops. For compressed air only the pressure dew point is significant. The atmospheric dew point is misleading and should not be used.
