Temperature probes

Temperature probes allow temperature to be measured via an NTC, PTC, RTD or other sensor. Widely used in industry, these wired probes are connected to devices to measure and analyze their signals. The choice of temperature sensor depends on the application and the constraints to which it is subjected.

What is a temperature probe?

Looking for a temperature measuring device. Still need to determine the type of probe you need? 

After all, temperature is one of the most measured values ​​in the world, and it's an essential reading for many processes. 
But be careful, it is necessary to have precise temperature control, because there is very little room for error if you do not receive an accurate measurement. 

But how do you choose the best temperature probe for your needs? Should you opt for a contact probe to measure materials or surfaces? Or use a sensor probe that measures the ambient temperature in the area around the object? Then you also have to choose between connected and wireless options, available temperature range, response time, presence of an LCD screen for temperature display, etc. All of these considerations should be taken into account when selecting your transducer. 

If you want to make sure you choose the right measuring instrument, be sure to follow this guide to find the best temperature probe for your needs. 

Contact temperature sensors

These types of temperature sensors must be in physical contact with the object to be detected. They use conduction to monitor temperature variations.

These measuring devices can be used to detect solids, liquids or gases over a wide temperature range.

There are three good reasons why you should use a contact temperature probe. 

  • The first is when you can establish a strong thermal connection with an object or fluid. 
  • Thanks to a wide measurement range, you can also use this probe when the estimated temperature is below -1700 degrees Celsius or above -40 degrees.
  • Finally, a contact probe is ideal thanks to a faster temperature reading than the other options available.

Non-contact temperature sensors

These types of temperature sensors use convection and radiation to monitor temperature changes. They can be used to detect liquids and gases that emit radiant or convective energy. 
These two types of contact or non-contact measurement probes can also be subdivided into three groups of sensors: 

  • electromechanical probe, 
  • resistive sensor, 
  • electronic probe. 

These three types are discussed below.

What is a temperature sensor used for?

There are several different industries that use probes to monitor temperature. 

The most common are automotive, medical and food. Each industry has specific requirements for its thermal measurement instruments. For example, in the food industry, a cooking temperature sensor is useful in determining if items are safe for consumption.

Depending on the industry, the selection criteria differ: resistance to high temperatures, high precision, response time, etc.
