A NEW optical tachometer has been developed by Ducklin Instruments Ltd and uses an infrared ray which is reflected from the moving object. The instrument itself has no moving parts and claims the manufacturer, is capable of measuring both rotary and linear motion from one revolution per minute to 30,000rpm in eight ranges to an accuracy of ±1 per cent in each range.
The tachometer can measure high-speed machinery from a distance of up to 305mm (12in). Accessories include a remote sensor for operation up to 20m (65.6ft) between probe and instrument, and a tripod for permanent mounting.
The retail price of the general purpose analogue tachometer is £130 plus vat.
