Contact probe

To take the temperature of solid surfaces, it is preferable to be equipped with a contact probe. High precision, reliability, robustness, and wide measurement range, these are the main characteristics of our contact sensors.

What is a contact temperature probe?

Contact temperature sensors measure their own temperature. We deduce the temperature of the object with which the sensor is in contact knowing that the two are in thermal equilibrium. That is, there is no heat flow between them. 

The contact probe is to be differentiated from the non-contact thermometer which uses convection and radiation to monitor temperature changes.

When should contact temperature probes be used?

1. Whenever you can make a good thermal contact with the object or the fluid

2. If the expected temperature is less than ~ 1 700 ° C or greater than approximately -40 ° C

3. If we can accept a reaction time superior to other technologies (plunger probes, screw-in probes etc ...)

Good thermal contact means that the sensor and the object or fluid are at or very close to the same temperature. This is generally the case when the dimensions and mass of the sensor are small compared to what is measured. You must maintain this physical contact by soldering, clamping, gluing, or using another reliable method to attach the sensor to the object.

Please note that for optimal use of your contact probe, we recommend that you read the instructions carefully. In particular concerning the operating conditions, namely the ambient temperature, the relative humidity, and the atmospheric pressure. 

What is a contact measurement probe used for?

Contact measurement probes can be used in different ways: 

  • measure the temperature present inside the pipes; 
  • detect the cold; 
  • perform surface temperature measurements of ferromagnetic objects, solid, flat and smooth substances,
