C.A. 1725 and C.A. 1727 tachometers

The C.A 1725 and C.A 1727 offer a range of 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 avoids external interference and the active, modulated infrared beam guarantees true measurements. For traditional contact measurement, a mechanical adapter (cylinder, cone or calibrated wheel) converts the rotation speed into pulses which are then measured by the tachometer. The third possibility is provided by an external input which can be used to connect the tachometers to a large number of sensors delivering voltage signals. Both models are equipped with MIN, MAX and measurement-smoothing functions. In addition, the C.A 1727 offers user-definable alarm thresholds and the possibility of recording and processing the data via its USB output with the TACHOGRAPH software. The digital display is a genuine control panel showing a 42-segment bargraph and all the useful information.
