The speed sensor SZCB-01 is a precision measuring element, and environmental protection measures should be taken for the signal connecting cable according to the on-site environment. Otherwise, the sensor is easily affected by the environment, leading to inaccurate measurement and even malfunction. In addition to environmental impacts, the speed sensor may malfunction due to various reasons. Yoyik introduces the following common speed sensor faults, hoping to be helpful to users of rotational speed sensors.

• Signal loss or instability:When the sensor SZCB-01 is disturbed, damaged, or the signal circuit has poor contact, it may cause signal loss or instability. This may lead to misjudgment of the control system, thereby affecting the operation of the steam turbine.

• Excessive deviation:The speed signal output by sensor SZCB-01 does not match the actual speed, which may be caused by excessive measurement deviation of the sensor.

• False alarm:Sensor SZCB-01 false alarm may cause emergency shutdown of the turbine, affecting the normal operation of the power plant.

• Other faults:The internal components of sensor SZCB-01 are damaged, and the wiring interface is loose, which may cause sensor faults.

Therefore, it is very important to regularly check the status and performance of the steam turbine speed sensor SZCB-01 to ensure its normal operation and timely detection and resolution of faults. In addition, it is strictly prohibited to carry out live disassembly and wiring of sensors. The wiring terminal must be firmly pressed and not loose. After wiring is completed, check that the cable and terminal contact are in good condition and there is no short circuit before powering on. To confirm the working power supply of the sensor, environmental protection measures should be taken for the signal connecting cable according to the on-site environment.
