The CMCP-TKSC Shaft Calibrator is used to determine the actual Proximity Probe System Output in mv/mil or mv/um of a machine shaft or piston rod. Proximity Probe Systems are calibrated by the manufactures to 200 mv/mil (7.87 mv/um) using a 4140 Steel as standard.

The actual machine shaft or rod response (sensitivity) to a Proximity Probes System can be quickly calculated by using the CMCP-TKSC measuring the actual target surface. Knowing the correct calibration allows the monitoring system to be adjusted to read vibration, thrust or rod drop correctly. Electrical or mechanical runout measurement can also be easily corrected for sensitivity

Using the CMCP-TKSC is straight forward. First, a proximity probe of known sensitivity is mounted in the CMCP-TKSC Armature and a few measurements are performed using a quality Voltmeter (DVM). Then the proximity probe, in the approximate center of its range, is gapped and compared to readings in 10 mil increments. A standard 200mv/mil proximity system, when viewing 4140 steel, will produce a 2.0 VDC change for every 10 mil change in the gap. The actual output change is simply divided by 10 and the actual sensitivity will be obtained in mv/mil or mv/um. The Delrin (non-metallic) base of the CMCP-TKSC will not affect the signal of proximity probe systems.

STI’s patented QuickClick micrometer allows the user to easily adjust the micrometer in 0.005” (English option) or 0.1mm (Metric option) increments quickly and reliably, improving the overall time it takes to complete calibration and with greater precision. The QuickClick can also be disengaged to allow for 0.001” or 0.01mm graduations.
