Leetsdale, PA- Schroeder Industries, a recognized leader in filtration and fluid conditioning products, introduces its TestMate® Contamination Monitors (TCM), the newest generation of particle monitors for continuous measurement of solid contamination in fluid. The TCM provides users with a smaller, tougher and more versatile stationary sensor. It provides instantaneous readings and is able to self-diagnose continuously with error vindication via the status LED. The monitor is designed for connection to hydraulic and lubrication lines with pressures up to 1450 psi (100 bar) and viscosities up to 4635 SUS (100 cSt). A small flow of oil is diverted for measurement purposes. Enclosed in a four-inch diameter case, the TCM utilizes an optical sensor and measure particles in four sizes: >4, >6, >14 and >21 microns. Measurement results can be output as a contamination code according to ISO 4406: 1999 or SAE AS 4059 (D).
