Chevrier Instruments is Canada’s top source for industrial tachometers. These are instruments that measure the rotation speed of a shaft or disk, as in a motor or similar machine. Although many of these devices display the number of revolutions per minute on a calibrated analog dial, digital displays have become more common in recent years. They are similar in concept to speedometers, but while speedometers are used to measure vehicle speed, a tachometer is designed for engines.
At Chevrier, we supply a range of tachometers from two primary manufacturers: KIMO Canada and Lutron. KIMO produces the CT 100 digital tachometer, which comes in two basic designs – the CT 100 O, which has a fixed optical probe, and the CT 100 C, which features a fixed optical probe with an ETC adaptor. The myriad functions of this instrument include rotation speed, unit selection, HOLD function, minimum and maximum values, an adjustable automatic shutoff, and an adjustable backlight. Users can also choose between optical and contact revolution counters.
The CT 100 tachometer uses two working principles: contact tachometry and optical tachometry. In contact tachometry, a rotating mirror inside the probe head reflects a light beam from a diode, and a light-sensitive cell detects the frequency of the beam signal, which is proportional to the rotation speed. In optical tachometry, a reflective tape on the rotating disk reflects the light beam.
Chevrier also supplies three kinds of tachometers from Lutron: DT1236L, which has a laser pointer; the DT2239 Stroboscope; and the DT2240D. The DT1236L’s laser pointer allows the user to take measurements up to two metres away, on a practical and safe device that is ideal for users who cannot approach the machine. The DT2239 has a stroboscopic blinking rate from 100 to 1,000 flickers per minute and a speed rate of 100 to 10,000 revolutions per minute. Meanwhile, the DT2240D can display four digits in figures half an inch high.
We also have tachometers and stroboscopes available from Imada, Monarch and REED Instruments, each with its own unique features and advantages.
