Overview
The Epro PR6423/10R-010 CON021 is an 8 mm eddy current proximity measurement system designed for non-contact shaft displacement and vibration measurement. It combines a PR6423 series probe with a CON021 signal converter to measure the movement of ferromagnetic targets. Furthermore, its 2 mm linear measurement range and defined initial air gap support accurate displacement monitoring under specified operating conditions.
Measurement Characteristics
The eddy current system measures the distance between the probe tip and a conductive ferromagnetic target without physical contact. As the shaft moves, the probe detects changes in the electromagnetic field and the CON021 converter processes the measurement signal.
The specified 2 mm linear measurement range provides the operating span for displacement measurement. Meanwhile, the 0.5 mm initial air gap defines the reference clearance between the probe and target during setup. Correct probe positioning is therefore important for maintaining the specified measurement characteristics.
Target Material and Measurement Accuracy
The specified target material is 42CrMo4 (AISI/SAE 4140) ferromagnetic steel. Using the defined target material helps maintain the expected relationship between probe displacement and output signal.
The deviation from best-fit straight line (DSL) is +/- 0.025 mm (+/- 1 mil) within an ambient temperature range of 0 to 45 deg C (+32 to +113 deg F). This specification describes the measurement linearity under the stated temperature conditions.
