Fixed Magnetic Tachometer

This instrument is used for measuring the rotating speed of various kinds of machinery and equipment with reverse and clockwise rotation or single-direction rotation, and is particularly suitable for measuring the rotating speed of dried firewood oil pump test beds, steam-turbine generators and other rotating bodies.

Main Technical Parameters

Operating conditions: ambient temperature of -20℃~50℃,relative humidity of less than 85%

Basic error: the basic error limit of the tachometer is ±1.5% of measurement upper limit at the temperature of 20℃±2℃.

Temperature influence:the indicating value change of the tachometer should not exceed the absolute value of basic error limit every time the temperature is changed by 10℃when the ambient temperature is changed within a specified range.
