Cable Probes

For cable probes, their temperature endurance depends on the insulation materials used. Here is a list of common materials and their temperature limits. Get in touch with our experts to find the best probe for your application.

• TPE: up to 105 °C
• TPC: up to 150 °C
• Silicone: up to 180 °C
• PTFE: up to 260 °C
• Fiberglass: up to max. 350 °C

For temperatures above 260 °C, we recommend a mineral insulated metal sheathed probe.

We manufacture our cable sensors as RTDs as well as thermocouples.

Pt100 cable probes and Pt1000 cable probes are almost linear in a wide temperature range and allow very accurate temperature measurements. However, for cable lengths of more than one metre, we recommend at least a 3-wire circuit with a Pt100. NTCs tend to come cheaper, but are suitable only for smaller temperature ranges. A thermocouple in the classic cable probe design is suitable for higher temperatures, especially in very dry environments.

Of course, this depends on your application. With compression and crimp fittings, you should be careful not to damage the stainless steel sleeve of the sensor.

If you want to use our overmoulded, waterproof cable sensors in combination with a heat-conducting paste, we recommend that you use a paste that we have tested.

For use as a surface probe, we have developed an adapter on the one hand and a specially shaped sensor (ICSKIN) on the other.

For temperatures below -50 and above 260 °C we recommend a sheathed sensor built from MIMS cable. It is mechanically more robust and optionally available with an integrated temperature transmitter.

A threaded probe is particularly interesting when measuring in tanks, boilers and pipes.

Regarding the response time of a sensor, the following rule of thumb applies: If you double the diameter, you quadruple the response time. So choose the diameter wisely!

As with all temperature sensors, the immersion length should be at least 5x the diameter of the sensor to avoid thermal bridges.
