This precision mechanical instrument enables technicians to physically adjust and measure the gap between a proximity probe tip and a target button to verify the transducer system's voltage-to-gap calibration curve. Outfitted with a high-accuracy metric spindle, this calibration kit ensures that machinery protection systems are matched to exact physical clearances before commissioning.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square;

Standard systems assume AISI 4140 steel. Calibrating a proximity system configured for 4140 steel against an incorrect target material block will distort the average scale factor (ASF), rendering the machine protection measurements inaccurate.\u003c\/p\u003e\n\n\u003ch4\u003eCommissioning \u0026amp; Calibration Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eBefore logging voltage readings, cycle the micrometer spindle across its full range three times to displace any grease or debris.
