C.A 1725 C.A 1727 Universal tachometers that you can count on! Industrial Tachometers 51 ◗◗ Measurements up to 100, 000 rpm ◗◗ Large number of functions, memories and automatic routines for data acquisition: measurement of rotation speed, linear speed, count, frequency and period ◗◗ xtensive programming possibilities E ◗◗ USB link for processing the results on a

Comprehensive and easy to use! One position, one unit! The rotary switch gives access to 7 measurement units: – tr/min The counting function can be used to measure directly in metres, feet or number of pulses. This means it is possible to measure a motor’s rotation speed, the pulse frequency or the contact opening time of a relay with the same instrument. (The functions indicated in italics are only available on the C.A 1727) When an object’s speed is irregular, it may prove necessary to apply smoothing to the measurement. This function computes a sliding average of the last 10 measurements....

3 possible types of measurement No-contact measurement… This involves measurement by photoreflection. The reflective strip placed on the part to be checked reflects the infrared beam. The optical sensor avoids problems with external interference and absence of light. Use of an active modulated infrared beam guarantees accurate measurements. … Contact measurement… A mechanism is available for converting a rotation speed into pulses measured by the tachometer. The mechanical adapter can be used with one of the three end-fittings: w  he cylinder and the cone for rotation speeds at the T end of a...
