The PMP from KOBOLD is a differential pressure sensor is designed to used for controlling and measuring the differential pressure of air or non-corrosive gases. It is specifically used for monitoring of filters or filter cartridges measuring the pressure difference before and after the chamber. The cleaning cycles can be driven by means of the programmable relay. If a differential pressure is attained, the rinsing procedure can be started. Therefore, the cleaning cycles can be optimized and considerable quantities of volume air can be saved. This device is usable with the ambient temperature range from -10 °C up to 60 °C and the maximum pressure of 750 m bar. It is enclosed with the protection degree of IP 65.
