Precision filter monitoring
February 2017, Pressure Measurement & Control

Kobold has on offer its type PMP differential pressure sensor, specifically designed for monitoring filters for air or non-corrosive/aggressive gases by measuring the pressure difference before and after the filter chamber. The compact microprocessor controlled unit is housed in a robust plastic casing with an enclosure class of IP65. Two hose connections allow for easy connection to the process before and after the filter.

The measuring range runs from 0 to 50 mbar. The measuring principle used registers even tiny pressure differences with great accuracy. The sensor is extremely safe against overloads up to 750 mbar. One 4-20 mA analog output and two relay outputs are available for the output of signals. The easy to operate electronics offers a large range of settings, which means that the relays, their time delay, the hysteresis as well as the analog signal are freely programmable. A four-digit LED display provides on the spot information.

Kobold PMP has application in the chemical industry and features small dimensions and easy installation and programmability. With the help of PMP differential pressure sensors, the cleaning or replacement of filters can be timeously carried out (depending on the degree of contamination) so that energy losses due to clogged or used filters can easily be avoided and costs saved.
