Thermopile Sensors: The Best Temperature Sensor

Thermopile sensors continue to gain popularity because of their design and high performance. The sensors are designed to calculate temperature by detecting objects from a distance with infrared energy. When the temperature rises, the infrared emits more energy.

Thermocouples contribute to the sensor’s high performance on silicon chips; it detects the temperature to give an output signal. These sensors play a crucial role in safeguarding your home, enhancing comfort, and saving energy.

Types of Thermopile Sensors 

The type of the sensor will differ according to the base metal. The variation in base metals and sensor materials dictates the temperature ranges. Check here for different types.

  • Type E: consists of chrome/constantan metal with a temperature range of -270° C to 1000° C
  • Type J: made with iron/constantan with a higher temperature range of -210° C to 1200° C
  • Type K: made with chromel/alumel where its temperature range from -270° C to 1372° C
  • Type N:  made from nicrosil/nisil metal with a typical temperature range of -270° C to 1300° C
  • Type T:  made with copper/constantan with a temperature range of -270° to 400° C
  • Type B: For a sturdy and refractory metals, you can choose type B platinum 30%/rhodium metals, and has a temperature range of 0° C to 1820° C
  • Type S: platinum 10%/ rhodium metals that will operate excellently  with a temperature range from -50° C to 1768° C
  • Type R: platinum 13%/rhodium metals which can be voted second best with a temperature range from -50° C to 1768° C
  • Type W: tungsten/rhenium metal; with this sensor, you can work on the broadest range of temperatures from 0° C to 2300° C.

 Here are the merits of acquiring thermopile sensors

Benefits of Thermopile Sensors

 There are many reasons why people choose these excelitas thermopile sensors, including


There is no need for external power to operate the sensor since there will be output once the temperature changes. This means the sensors are self-sufficient. 

Simple and Sturdy

It may look simple, but the sensors are tough since they are constructed from different sturdy metals like iron, aluminum, copper, and platinum. Thus these sensors can stand in different environments in company applications.

Low Cost

These sensors are known for their pocket-friendly prices, especially when compared with RTDs.

Wide Temperature Range 

Thermopile sensors can measure a wide range of temperatures from -200 to 2500 degrees Celsius. They provide accurate temperature in an industry operation with extreme temperatures.

they can be in different industrial applications like 

  • fog machines
  • gas turbines
  • electric arc furnace 
  • automotive diesel engine industrial ovens 
  • millivolt gas control systems 

Small in Size

The sensor has a small junction that can be installed easily.

Come in Different Types

The sensors come in different varieties, giving a platform to choose according to your preference. 


Suppose you are looking for an effective sensor to detect temperature. In that case, thermopile sensors should be your first choice because of their wide range of benefits, such as they are cheap, they can measure temperatures in a wide range and is easy to use, among others, make them the ideal solution.
