Temperature sensor is a device that is designed to measure the degree of hotness or coolness in an object. The working of a temperature meter depends upon the voltage across the diode. The temperature change is directly proportional to the diode’s resistance. The cooler the temperature, lesser will be the resistance, and vice-versa.

PT100 Sensor are constructed in a number of forms and offer greater stability, accuracy and repeatability in some cases than thermocouples. 

The advantages of platinum resistance thermometers include:

• High accuracy
• Low drift
• Wide operating range
• Suitability for precision applications.

 

The Dial Type Oil Temperature Indicator - Model 1706A is a specific model of an analog OTI (Oil Temperature Indicator) used in industrial applications, particularly for monitoring the top oil temperature in power and distribution transformers.
