Robust and compact trigger / RPM sensor

The Laser Trigger sensor is used for contact-free measurement of machine speeds.

This sensor uses red laser light emitted from the sensor head.

The bundled laser beam impinges on a measurement mark on the rotating shaft and is reflected back with every rotation.  Every time the optical system measures the reflected light, the sensor emits an electrical pulse.

The measurement device – VIBXPERT, VIBSCANNER – calculates the shaft speed based on the rate of repetition of this voltage pulse.

The laser trigger sensor is mounted on the machine using the trigger stand (VIB 6.632).
