This tachometer probe is ideal for electric motor maintenance.
Measurement is performed by photo-reflection, allowing no-contact measurement: a reflective strip is positioned on the rotating part to be checked.
The probe converts the rotation speed into voltage pulses on 2 x 4 mm isolated banana plugs.
The CA 1711 probe can be connected to a Chauvin Arnoux
CA 8220 power analyser. The switch on the CA 8220 must then be set to RPM.
The motor's rotation speed will then be displayed directly.
