optical rotational speed sensor / with angle measurement

Tacho-Probe-01 & Tacho-Probe-02

Both sensors are emitting light which is reflected from an object and received by a photo transistor. The output of this sensor is an analog voltage signal.

Connected to an analog input of any DEWETRON system, the RPM and angle information are extracted in the software. You can see the shape of the curve, and can define the trigger level in the prepared angle mathematic of the software.


Tacho-Probe-03

The Tacho-Probe-03 has a laser and is used with the included retroreflective tape. It has the advantage that in can be located 15 mm to at least 700 mm from the test object.
