Surface sensor installation

Q&A Temperature

Hi. I need information for a surface RTD installation on pipes. Can you help?

Expert’s answer: Surface sensor installation

Sure, we’ll brief you on surface sensor installation! For starters, most solutions on the market will require good insulation. The vendors say that great insulation makes for great accuracy.

As for installation, it depends on the device. It can vary from super simple, like a clamp-on sensor, to kind of complicated, like an inline sensor.

While the clamp-on sensor for pipes gives you an easy setup, the inline gives you better accuracy. It may take extra work, but we’d go with installing the sensor centerline. That way, you’ll eliminate the temperature difference between the wall and the center of the pipe.

On the other hand, if you don’t need high accuracy, then the external sensor can provide the data you need. Remember that you still need good insulation to get the best performance!
