Dewpoint probe and process pressure probe

25 January 2018

Suitable for compressed air systems and dryers, Rotronic's new low dew point stainless steel probe with screw-in connector is suitable for for measurement down to -60°Cdp in industrial processes at up to 100 bar.

Dew point temperature is a key indicator of high water vapour in compressed air systems. If the dew point temperature is the same as the temperature of the compressed air, water vapour will condense and there will be unwanted water in the compressed air lines. This causes erosion, corrosion, freezing and can adversely affect product quality during production processes. A batch of product may even be rejected due to contamination resulting in increased costs. As the pressure increases the dew point temperature rises and approaches saturation. It is important to measure dew point precisely and reliably.

The probe provides stable measurements and is fully compatible with Rotronic measurement transmitters, handhelds and the company's continuous monitoring system (RMS). Measurement chambers with a defined air flow and a quick connector for optimum dew point measurement are available. Monitoring and control of dew point is easily possible, improving system efficiency and eliminating the possibility of product contamination.

Also from Rotronic, the BF220 absolute pressure transmitter with piezo-resistive steel sensor, robust stainless steel housing and ½in G fitting is suitable for measurement in compressed air lines, as well as neutral gases and nitrogen in piping and closed vessels. It can be used for applications with fast temperature changes and has a measurement range of 0 -to10 bar.
