Permitted process pressure at the protection armature
The maximum process pressure is 40 bar (600 psi). It is limited further by the process connection in question.

Permitted flow velocity depending on the immersion length
The highest flow velocity tolerated by the thermometer diminishes with increasing immersion length exposed
to the stream of the fluid. In addition it is dependent on the diameter of the thermometer tip, on the kind of
measuring medium, on the process temperature and on the process pressure. The following figures exemplify
the maximum permitted flow velocities in water and superheated steam at a process pressure of
4 MPa
(40 bar = 580 PSI)
