CS-20-SL Heavy Duty Speed, Length Contact and Non-Contact Digital Tachometer

The CS-20-SL Combination Hand-Held Digital Tachometer combines the best features of both contact and non-contact models to accurately measure RPM, surface speed and length.
This model the measuring wheel has additonal flanges to simplify centering the cable on the measuring wheel.

When the non-contact mode is used, rotational speed (RPM) is measured using a visible beam of light. The CS-20-SL 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-SL'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-SL 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.

  • Built-in memory stores maximum, minimum, average and last reading for recall to the display
  • NIST Certification included at no additional cost
  • Accuracy of 0.02% with a resolution of 0.01 RPM
  • Measures speeds from as low as 1.00 rpm up to 99,999 rpm
  • Molded Rubber Shell Provides Additional Physical & Environmental Protection
  • Can be set for use with 2 optional-sized surface speed wheel (6 inch or 12 inch)
  • Ideal for measuring speed and length of yarn, fibre and wire
