Track spindle growth and gap changes
Define temperature drift, mounting geometry and resolution at the bandwidth your control loop needs.
EDDY CURRENT SENSORS / COMPLETE MEASURING SYSTEMS
Eddy current sensors.
Critical movements.
Clearly measured.
Non-contact eddy current displacement sensors and shaft vibration proximity probes. Start with your target metal, measuring range and signal chain.
SELECT BY MEASUREMENT
Four paths from motion to a usable signal
01 / ECS-NCDT
Eddy current displacement & distance sensors
Continuous, non-contact measurement for spindle thermal growth, precision positioning and conductive-target gap metrology.
- Selection envelope
- 0.5–15 mm requested range
- Typical interface
- 0–10 V / ±10 V / 4–20 mA / RS485 review
02 / ECS-3300
Eddy current shaft vibration & proximity probes
Review a complete probe, extension cable and driver assembly for radial vibration, eccentricity and axial thrust-position monitoring.
- Selection envelope
- 2 / 4 / 12 mm inquiry options
- Typical interface
- Raw gap voltage / dedicated 4–20 mA transmitter
03 / ECS-AUTO
High-speed RPM & automotive eddy sensors
Specify shaft phase-reference pulses, turbocharger blade-passing signals and dynamic tip clearance around the actual target geometry.
- Selection envelope
- RPM / blade count / gap defined together
- Typical interface
- Pulse speed / analog clearance, by configuration
04 / ECS-HT
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.
- Selection envelope
- +200 / +250 / +350 °C requested conditions
- Typical interface
- Remote single- or multi-channel conditioner
AISI 4140 ≠ ALUMINUM 6061
Your target metal belongs in the calibration.
Conductivity, magnetic permeability, thickness and curvature affect the sensor response. A curve calibrated on shaft steel cannot simply be assumed correct on aluminum or stainless steel.
Request target-material calibration ↗Match the entire proximity system
Review radial vibration, thrust position and eccentricity with the monitor, cable length and target steel.
Connect RPM to blade-passing frequency
Bring blade count, target geometry and gap to the speed-sensor discussion, alongside the acquisition bandwidth.
A distance curve or a switching point?
| 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.
Give engineering the details that decide fit.
Target material, range, output and full system length. Add an existing model for a replacement review.
