Dimensions
Characteristics
Clamp-on temperature sensor GTL737 is specified to measure
temperatures without media contact.
The measuring tip is directly located at the pipe wall and will be
fixed by the clamp-on adapter on the pipe. This measuring process
provides a high accuracy and a fast response time, which is often
better than a measuring principle with media contact.
