Detailed Description of Spare Parts
Wiper Blades (Order No. 71156817)
This spare part includes 2 complete wiper blades, which are wearing parts of the wiper system. When cleaning performance decreases or the blades are noticeably worn, they should be replaced promptly. Suitable for all CUS71D sensors with wiper function.
Wiper Motor (Order No. 71156830)
Provides a complete wiper motor assembly. If the motor makes abnormal noises, stops rotating, or has insufficient torque, this part needs to be replaced. When replacing, ensure the power is disconnected and follow the instructions for wiring.
Wiper Coupling (Order No. 71156832)
Includes 2 wiper motor couplings, used to connect the motor and wiper shaft. Worn couplings may cause unsmooth wiper movement or slipping. Regular inspection and replacement are recommended.
Wiper Piston (Order No. 71156833)
This spare part is 1 wiper shaft with bearing, a key component of the wiper drive. If the shaft wobbles or rotational resistance increases, this piston assembly should be replaced.
Sensor Protection Kit (Order No. 71404869)
Kit CUS71D sensor protection v. 2 is a sensor protection kit that effectively prevents mechanical damage or contamination of the sensor and extends its service life. It is recommended to install and use it under harsh operating conditions.
Selection and Procurement Recommendations
- Confirm whether your CUS71D sensor is equipped with a wiper function; the above wiper spare parts are only applicable to models with wiper.
- Select the corresponding spare parts based on the fault symptoms: for poor cleaning performance, check the wiper blades first; for abnormal movement, check the motor, coupling, and piston.
- It is recommended to stock commonly used wearing parts, such as wiper blades and couplings, to reduce downtime.
- When purchasing, please provide the complete order number to ensure consistency with the original parts.
Proper selection and timely replacement of spare parts can ensure the long-term stable operation of the CUS71D turbidity sensor and improve the accuracy of water quality monitoring data.
