Rotation speed is an important operational monitoring parameter for steam turbine units. RZQW-03A tachometer is an instrument specially used to monitor the speed of steam turbine and the status of emergency governor. It displays the speed value of the turbine through a display panel. But when the system malfunctions, the speed value may not be displayed correctly. Yoyik introduces some common reasons for displaying numerical errors.

The input signal of rotational speed monitor RZQW-03A comes from the speed sensor. If the sensor is installed in an incorrect position, it may not be able to accurately sense the rotational motion of the rotor or shaft, resulting in incorrect display of speed values. Secondly, when the speed sensor malfunctions or is damaged, it can also lead to an inability to accurately perceive the rotational motion of the rotor or shaft. In addition, the signal of the speed sensor may be subject to interference from other devices or systems, such as electromagnetic interference or vibration interference. These interferences may cause distortion or instability in the speed signal output by the sensor, thereby affecting the accurate display of speed values.

For RZQW-03A tachometer itself, its power supply stability is crucial to accurate speed value display. If there is a problem with the power supply, such as a high or low voltage, it may cause unstable operation of the instrument, leading to incorrect display of speed values.
