FilterSense PS Series particulate sensors are unique, robust, passive sensors that connect to DynaCHARGETM and B-PACTM control units. These sensors are free of electronics. Heat and vibration do not reduce accuracy or life of the sensor. They enable intrinsic safety for line powered control units and make for more accessible installations since many filtration monitoring points are difficult to access. The PS 10-HP has proven to be the most reliable and durable sensor available.
