The CS-20 Combination Hand-Held Digital Tachometer combines the best features of both contact and non-contact models to accurately measure RPM, surface speed and length.
When the non-contact mode is used, rotational speed (RPM) is measured using a visible beam of light. The CDT-2000HD can be up to 24 inches away from the small piece of reflective tape that is affixed to the rotating element. When operating in the contact mode, the speed is sensed by directly contacting rotating device using one of the contact adapters supplied with the instrument.
The CS-20's rugged construction, portability and outstanding features make it an perfect choice for use in maintenance processes. It is ideal for machine operators in a wide variety of machinery and material handling applications.
In various applications where surface or linear speeds are to be measured, the universal wheel is used. The CS-20 can also be used to measure the accumulated total of continuously running material such as paper, wire being wound on a spool, or to check the calibration of on-line counters and totalizers.
Special model CS-20-SL
On this model the measuring
wheel has additonal flanges to simplify centering the cable on the measuring wheel.
