Multiquip 43133-01 PEC Multilevel Sensor 6.5" - OEM Replacement Part

The PEC Multilevel Sensor is a critical component in the motor speed control system of ride-on power trowels, providing real-time feedback to maintain proper motor operation and prevent control failures. This 6.5" sensor monitors motor parameters and triggers the amber warning lamp when sensor faults occur, including open circuit conditions or when frequency differences between signals exceed 5%. When this sensor fails or becomes corrupted, the motor speed control switches to open loop operation, significantly reducing trowel performance and precision.

Sensor failure symptoms include amber warning lamp activation, open loop motor control, and error codes indicating sensor open circuit or corrupt parameters. The troubleshooting manual specifically identifies this sensor in diagnostic procedures for motor speed control issues. Regular inspection of sensor wiring and connectors is recommended to prevent failure during operation.

Compatible with the following Multiquip models:

• STXDF Ride-On Trowel
