Monitor Technologies' TrueCap® RF capacitance sensors offer cost-effective point level monitoring with reliability you can count on. Monitor’s complete line, which features models MK-2 and MK-2e, provides you with the most affordable solution for your application. Monitor’s RF capacitance probes are designed to provide a high level of sensitivity, stability and durability for powder and bulk solids applications, as well as liquid and slurry applications. The driven shield section of the probe enables the circuitry to ignore material build-up on the probe that would otherwise cause false sensing. The MK2 Model also includes push-button calibration, sensitivity selection & self-test.
