The document describes a non-contact eddy current sensor called CMSS, which is used for distance measurement on aluminum and steel. It has a measurement range of up to 7.6 mm, a linearity of less than 1%, a sensitivity of 200 mV / 25.4 µm, and is suitable for fast motion changes (up to 10 kHz). It operates in a temperature range of -35 to +177°C and is unaffected by non-metallic media in the measurement environment (such as water, oils, contamination, plastics). Additionally, it can be used for distance measurement on static and rotating objects, as well as for measuring imbalance and vibration, and non-contact quality control in automation.
This manual covers the CMSS family of eddy‑current displacement sensors (CMSS65, CMSS68, CMSS62, CMSS665, CMSS668, CMSS620‑2). It lists measurement ranges, linearity, frequency response, temperature limits and sensitivity for each model, as well as standard cable lengths and power‑supply requirements.
Installation guidance explains how to mount the sensor on metallic and non‑metallic parts, required clearance to the sensor tip, calibration with the reinforcement unit, and wiring using the EA‑PS 624 power supply. Accessories such as power modules and extended‑length sensors are also described. This manual is written in German.
| Measurement range (CMSS65) | 0.254–2.032 mm |
|---|---|
| Frequency range (CMSS65) | DC–10 kHz |
| Operating temperature (CMSS65) | -35 °C to +177 °C |
| Sensitivity (CMSS65) | 200 mV/25.4 µm |
| Standard cable length (CMSS65) | 1 m |
The standard cable length for the CMSS65 sensor is 1 meter.
The sensors operate from –35 °C up to +177 °C.
When mounted on metal, a gap must be kept to the sensor tip; the sensor should be held cylindrically with three‑times or 45° cone shape relative to the tip.
