one.Water temperature sensor application environment description
water temperature sensor is a compact, fully integrated temperature recorder for measuring water temperature. It is suitable for use in a variety of industries.Water temperature sensor is widely used in industrial cooling, sewage treatment, aquaculture, environmental monitoring, HVAC systems and other fields.They are used to monitor water temperature in real time to ensure efficient and safe operation of the system.For example, power and chemical plants need to monitor the cooling water temperature to prevent equipment from overheating; aquaculture farms need to adjust the water temperature to promote biological growth; environmental monitoring can assess the ecological health of water bodies.The sensor's working environment is varied, and the equipment has waterproof, corrosion-proof, and anti-interference characteristics.

three.water temperature sensor installation and electrical connection
1.Water temperature sensor installation

Installation distance requirements: Keep it more than 5cm from the side wall and more than 10cm from the bottom.
Installation environment: Cannot work in strong light, try to be in a dark environment.No other fluorescent substances that can be excited can be present.
2.Electrical installation
The cable is a 4-core shielded wire, and the line sequence is defined:
Red - Power cord (12~24VDC)
Blue-ground (GND)
Green-485B, Yellow-485A
Before powering on, carefully check the wiring sequence to avoid unnecessary losses caused by wiring errors.
Note: The color of the cable may vary slightly depending on the production batch.The specific color of the cable is subject to the silk screen printing.
Four.water temperature sensor maintenance and maintenance
1.When the sensor has a long time to use and maintain the sensor, it can be calibrated and corrected by matching the instrument.When the sensor is still unable to be calibrated and measured, it means that the sensor has failed.Please replace the sensor.
