Please note the General information on temperature measuring devices.

The load specifications are based in part on highly simplified assumptions for the mechanical stresses occurring in the protective conduits under idealized operating conditions. For example, pulsating incident flows are not taken into account. The data can therefore only be of an indicative nature for thermowells under real operating conditions. They do not provide complete security against breakage or tearing.

This specification refers to our current standard with regard to design, dimensions and materials. JAKO Messtechnik GmbH reserves the right to make changes or modifications without prior notice.
