Working Principle

The 66F085 is a temperature sensor based on resistance temperature detectors (RTDs). It consists of a platinum element that changes its resistance with temperature. The 66F085 also uses a Wheatstone bridge circuit to provide superior linearity and resolution over wide temperature ranges. The Wheatstone bridge gives the 66F085 the capability to measure temperatures from -40°C to +125°C with a resolution of 0.02°C and better than 0.2°C accuracy over the entire range. The Wheatstone bridge is kept in balance by setting the reference voltage and current to appropriate values. This is done through the use of two external voltage references, connected to the sensor terminals. The output voltage is proportional to the sensed temperature.

Conclusion

The 66F085 temperature sensor is a reliable and accurate temperature sensor that can be used in a wide range of applications. It is capable of measuring temperatures ranging from -40°C to +125°C, with a resolution of 0.02°C and better than 0.2°C accuracy over the entire range. It uses a Wheatstone bridge circuit to provide superior linearity and resolution over the entire temperature range. The 66F085 is an ideal choice for automotive, industrial and consumer applications, such as radiators, air conditioning systems, kitchen appliances, safety systems, and so on.
