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.
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.
