Specify continuous temperature, peak temperature and exposure time independently for the probe, cable, connector and electronics. A +380°C request requires a separately qualified assembly.

High-temperature ceramic eddy current probes
Review ceramic sensing heads, armored or mineral-insulated coaxial cables and remote signal conditioners for hot-zone gap measurement.

Define the conditions behind the measurement
Confirm atmosphere, pressure, thermal cycling, cable bend radius and mounting expansion. Temperature ratings cannot be transferred between different cable and sealing constructions.
Provide the target material at operating temperature and allow for conductivity changes. Radiation, pressure and hazardous-area approvals require their own evidence; they are not implied by a ceramic tip.
Listed ranges and interfaces are inquiry options. Approved ratings, drawings and calibration data belong to the selected configuration.
Metal grade, thickness and curvature change the curve.
Request factory linearization for AISI 4140 / 42CrMo, aluminum 6061, stainless steel 304 / 316, copper or titanium. Confirm the representative target and calibration conditions in your quote.
| Decision | Eddy current displacement system | Standard inductive proximity switch |
|---|---|---|
| Measurement | Continuous distance or dynamic motion | Target present / absent |
| Output | Calibrated voltage, current or digital distance | Discrete ON / OFF |
| Specify | Range, resolution at bandwidth, target and calibration | Switching distance, hysteresis and switching frequency |
Analog inductive distance sensors also exist. Compare the actual measurement principle and performance, rather than the category name alone.
Before you approve the measuring system
Can the same calibration be used on steel and aluminum?
Do not assume so. Specify the material grade, thickness and curvature and agree the calibration curve for your target.
Can a replacement probe be mixed with an existing driver?
Only after the exact probe, electrical length, driver, target and output curve have been qualified together. Connector fit alone is insufficient.
What does a configuration quote include?
Request a matched probe, cable and conditioner, selected mounting accessories, calibration conditions, performance evidence and confirmed price and delivery.
