Noncontact tachometer is precise about speed

A new intrinsically safe, multifunction tachometer provides noncontact laser measurement of rotational or linear devices.

A new intrinsically safe, multifunction tachometer provides noncontact laser measurement of rotational or linear devices.

Two models are available, both offering users the choice of measurement in revolutions per minute, radians per second, or metres, feet, or yards per minute or second.

Equipped with contact adapters, the TMRT 1 and TMRT 1Ex can also measure distances or count revolutions and measure time intervals.

The large LCD is easy to read even when the unit is pointing down into machinery and an angular range of +/-80 degrees facilitates measurement in areas where straight-line access is difficult.

Features and benefits include a speed range of up to 99,999rev/min, high resolution at low speeds and measurement accuracy of +/-0.01% or +/-1 digit of reading.

The laser optical system allows easy and quick measurement to be made at a safe distance from rotating machinery.

The TMRT 1Ex has been certified according to the latest ATEX standards for use in potentially explosive hazardous areas, making the TMRT series suitable for any industry where motion and/or speed needs to be monitored accurately.

Typically this includes applications with electric motors, pumps, compressors, centrifuges, fans, blowers, generators, turbines, hydraulic motors and air motors.

On a broader front educational establishments and R and D sites can benefit, as can automotive garages where engine and transmission shaft speed has to be measured.

Running on four AAA alkaline cells, the tachometers have an operating temperature range of 0 to 40C and are supplied with a carrying case for protection and portability.
