Contamination class transmitter (CCT 01-Set) with an integrated, three-channel particle counter, combined with the particle flow sensor (PFS 01 laser sensor). Eaton’s in-line measuring systems are designed to mount directly to stationary systems for continuous or periodic monitoring, or can be used as mobile monitoring solutions in hydraulic and lubricating systems. Immediate and accurate diagnoses enables the operator to influence the system or intervene with appropriate counteractive measures when necessary.
