Measure Fan Speed Rotation

Measure Fan Speed Rotation

Measure the rotation speed of a fan without contact. (Non Contact Tachometer)

Highlights

  • The rotation speed of a fan can be measured safely without contacting it at a distance of up to 500 mm.
  • Measurement can be performed at the point of either the blade or shaft of the fan.
  • Rotation speed is measured by counting the pulses of light reflecting off the reflective tape.
  • Treatment is made to reduce the influence of direct sunlight.
  • Use of the analog and pulse output of the FT3406 Tacho HiTester (Tachometer) enable measuring changes in the rotation speed with a data logger.

How to Use

  • Put the 9211 Reflective Tape on the measurement location.
  • Focus the light from the FT3405 or FT6406 Tacho HiTester (Tachometer) on the reflective tape.
  • The measurement distance is 50 to 500 mm and the measurement range is 30 to 99990 rpm.
