CABLE PROBES

Traditional Cable Probes

Cable probes are the simplest construction of temperature sensors. Typically, the sensing element is protected by a metal or plastic cap. This traditional construction offers quick response times and works well in dry environments. But as soon as water tightness comes into play, it bears problems.

Overmoulded Cable Probes

Therefore, we have invented what we call overmoulded probe or “rubber probe”. Here, the sensing element is protected by a mould made from the same material as the cable. This ensures superior water tightness and resistance to vibration. 

We Recommend...

In completely dry conditions, traditional cable probes are just fine. As soon as humidity, condensation and freezing come into play, you are better off with a overmoulded probe. If humidity is a problem and temperatures can exceed 150 °C, a mineral insulated probe may be the best solution.

MORE INFORMATIONS

Which sensing element should you choose?

Typically, low-cost cable probes come with NTC sensors. If the temperature range of an NTC is not enough, a Pt1000 can be a good solution. The choice comes down to your application and requirements. Get in touch with our experts and we are happy to find the best solution for you!

Limitations of cable probes

The temperature limits of cable probes are determined by the cable material. If you want to learn more about this, check out our guide on the different cable materials and their temperature range.

If your required temperature range goes below -40 °C or above 260 °C, our mineral insulated probes will work best for you.
