- These instruments are simple to use and offer numerous measurement possibilities with or without contact.
- Measurement by photo-reflection for no-contact measurement: a reflective strip is positioned on the part to be tested. The optical sensor helps to prevent external disturbances and the active, modulated infrared beam guarantees correct measurements.
- For traditional measurement with contact, a mechanical adapter (cylinder, cone or calibrated wheel) converts the rotation speed into pulses which are then measured by the tachometer.
- Third possibility: an external input allowing a large number of sensors delivering voltage signals to be connected to the tachometer.
- The digital display is a genuine control panel showing a 42-segment bargraph accompanied by useful information: confirmation of signal reception, functions selected, alarm thresholds, etc.
- The rotary switch gives direct access to 7 different measurement units (RPM, Hz, etc.) and each key on the keyboard corresponds to a function (MIN MAX, Smoothing, alarms, etc.).
