Fans play a vital role in the industrial field, however, fans run for a long time will produce a lot of heat. In order to ensure the safe and stable operation of fans, the temperature sensors are widely used in fan systems.

I. Selecting the right temperature sensor
 When selecting temperature sensors for fans, there are several key factors to consider. The first is the sensor's measuring range and accuracy, should be based on the actual application requirements to select the appropriate measuring range and accuracy. At the same time, the response time of the sensor is also an important factor, to ensure that it can accurately reflect the temperature changes in the fan system in a timely manner.

Second, the sensor layout position
 The arrangement position of the temperature sensor has an impact on the accuracy and response speed of the measurement results. In the fan system, should choose to arrange in the fan heat sink or radiator near the location, in order to sense the temperature changes in the fan system in a timely manner. Arrangement location should try to avoid direct radiation of heat source or local temperature uneven place, in order to ensure the accuracy of the measurement results.

Third, the sensor's protection measures
 Due to the complexity of the fan's working environment, the temperature sensor is susceptible to dust, moisture and other effects of the external environment. In order to ensure the normal operation of the sensor, appropriate protective measures should be taken, such as the addition of shields or seals to prevent dust and moisture from entering the sensor.

Fourth, the sensor's signal transmission and processing
 Temperature sensors usually output temperature values by means of an electrical signal. In wind turbine systems, the signal transmission distance of the sensors may be long, so the transmission method of the sensor signals and the use of signal amplifiers should be considered. In addition, in order to effectively utilize the data from the temperature sensors, it is necessary to equip an appropriate data acquisition and processing system for real-time monitoring and recording of temperature changes in the wind turbine system.

Conclusion:
 Temperature sensors for fans play a vital role in fan systems. Correctly selecting the appropriate sensor, reasonably arranging the location of the sensor, taking appropriate protective measures and equipping the corresponding signal transmission and processing system can ensure the safe and stable operation of the fan system. In the future, with the continuous progress of technology, the accuracy and reliability of temperature sensors for wind turbines will be further improved to provide better support for the intelligent and automated development of wind turbine systems.
