Tighten the pressure transmitter with a suitable torque spanner using the spanner flats.
When there is a cooling element, the lower hexagon should be used for tightening.
The correct torque depends on the dimension of the pressure connection and the sealing used (form/material). The
maximum torque is 50 Nm.
The specified tightening torque for the high-pressure pipes must be adhered to (see pipe supplier's specifications).
Non-compliance can damage the instrument or the measuring point.
