METPOINT^® DPM: Sensor technology for precise pressure dew point measurement

Humidity in compressed air applications is a problem and can, in most cases, damage the system and contaminate end products. The ideal instrument for monitoring residual moisture is the pressure dewpoint sensor METPOINT DPM. Our sensor technology enables you to accurately measure the degree of humidity or the pressure dew point at critical flow points in your compressed air system. This information is indispensable for operators who want to improve the quality of their compressed air whilst saving energy and costs.

Do you use high-quality dry compressed air in your production process?

This is particularly important in sensitive areas where very high hygiene standards must be maintained and where compressed air comes into direct or indirect contact with the product. The METPOINT DPM stationary pressure dew point transmitter measures the most critical parameters for compressed air and technical gases i.e. temperature, relative humidity and dew point (down to -60 °Ctd).

But that is not all: The METPOINT DPM sensor provides information regarding the functional capabilities for components and the measurement provides the basic data for the optimum dimensioning for your system. The METPOINT DPM sensor is therefore not just a safety guarantee in your process chain, rather also an instrument for increasing production efficiency.

The pressure dew point measurement is executed continuously and the results can be visualised on the optional METPOINT BDL compact or METPOINT BDL portable The pressure dew point measurement is executed continuously and the results can be visualised on the optional

Operating principle of dewpoint sensor

With the temperature, the relative humidity and the dew point , mobile and stationary dew point measuring devices made by BEKO TECHNOLOGIES precisely measure the critical parameters in compressed air and other gases.

Our calibration service for your METPOINT^® DPM

Measurement transducers and transmitters are exposed to mechanical stress and temperature fluctuations. As a result e.g. the measuring accuracy of the sensors decreases and generates a so-called “drift”, which then falsifies the measured results and can thereby impair production quality and/or product quality. BEKO TECHNOLOGIES provides a comprehensive range of calibration services for volume flow sensors, pressure dew point transmitters, pressure measurement converters and analyses devices. The calibration is executed according to a specified calibration method from BEKO TECHNOLOGIES and is a so-called ISO calibration. ISO calibration is based on reference measurements performed with externally provided test specimens and certified reference devices. All reference devices can be traced back to national standards. The relevant procedures and methods meet the requirements of the DIN EN ISO 9001 quality standard.
