CZ-20A

Fixed Magnetic Tachometer

CZ-20A fixed magnetic tachometer is used for measuring the rotating speed of rotating shafts of various kinds of low-speed machinery and equipment.

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.

Range of oscillation:the pointer can swing slightly during operation of the tachometer, while the range of oscillation cannot exceed the absolute value of basic error limit.

Homodromous rotation: the pointer of the tachometer rotates clockwise in a single direction; the rotating shaft and the pointer rotate in the same direction.

Dust prevention: the tachometer is equipped with a sealing device which has the effect of dust prevention.
