Threaded Probes

We are happy to support you in your selection process. Important questions are:

• in which medium do you want to measure the temperature?
• what kind of process connection do you need (thread size, thread type, mounting adaptors, etc.)?
• in which temperature range do you want to measure?
• what is the ambient temperature at the probe?
• how do you want to connect the probe?
• which output signal do you need (Pt100, Pt1000, NTC, 0-10V, 4-20mA, Modbus, IO-Link…)?

Together we will find the best threaded probe for your requirements. Get in touch with our experts now!

For applications where high accuracy over a wider temperature range is required, Pt100 screw-in probes and Pt1000 screw-in probes are particularly suitable. If you want to measure in a comparatively small temperature range, a less expensive NTC screw-in probe can also be a good choice.

The choice ultimately depends on your application and your requirements. Our experts are happy to help you!

Very often. Our integrated temperature transmitters provide higher accuracy. They also convert the weak, interference-sensitive signal of the Pt100 into a more robust one such as 0-10V or 4-20mA. Even better: go for a digital transmitter with Modbus RTU right away.

Removing a screw-in probe automatically means that you have to open the process. This means you have to empty the boiler or stop the process before you can unscrew the probe. In some applications this is not an option.

Then a sheathed sensor mounted in a thermowell is a fantastic alternative. This is also optionally available with an integrated temperature transmitter.

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.
