Linear displacement sensor HPC-75

non-contactcapacitiveresistance

HPC-75 Series Cylindrical Probes for Precision Dimensional Measurement Capacitec’s HPC non-contact probes are our most popular line of capacitive sensors. The ensor and guard elements are provided in a protective metal case. The HPC family of probes supports cable lengths of up to 10 meters in standard applications. Built in wrench fl ats allow for easy installation and adjustments. A set screw or split clamp housing typically holds the assembly in place for easy installation and adjustments. Capacitec also off ers custom confi gurations. Please consult the Capacitec technical support team for more information. Notes Range and signal to point ratio will be degraded by longer cable lengths. Calibrations: Upon order placement customers must specify their calibration requirements. The calibration is based on the customer’s required linear range shown in voltage output per distance. All Capacitec sensor systems come with a factory calibration based on the customer’s requirements. A calibration results sheet, traceable to NIST is included in each shipment. A 20-point archived calibration record of voltage output vs. nominal displacement is provided standard with every probe. Sensor must be calibrated with final length of cable for stated results. Electricals: The guard element is driven with an electronic voltage 2—20 Volts P - P maximum and must not be grounded. All components are electronically isolated from each other by >20 megohm of leakage resistance (at room temperature) for best operation with the instrumentation. -D dip coatings also prevent the driver, sensor, and guard elements from being accidentally earth grounded or shorted.
