regulations.
4. Mounting
4.1 Mechanical mounting
Only use the pressure switch if it is in perfect condition with respect to safety.
Prior to commissioning, the pressure switch must be subjected to a visual inspection.
Leaking liquid is indicative of damage.
■
Obvious damage must be reported immediately.
■
With a high ambient temperature and a high UV irradiation, the pressure switch must be installed with additional
■
covering in order to avoid damage to the digital indicator and buttons.

Mounting instructions for process connections G 1 hygienic and TRI-CLAMP
Never loosen sealed filling screws on the measuring instrument.
■
For installation, in accordance with the fitting and flange standards the appropriate fastenings, such as screws, nuts
■
or clamp rings, must be used.
For flange mounting, only use sealings with a sufficiently large inner diameter and centre them. Contact with the
■
diaphragm leads to measuring deviations.
When using a welding socket, position this so that the hole for leakage detection points downwards. Weld the
■
welding socket flush with the inner wall of the vessel and grind down. The surface roughness of the ground surfaces
must be Ra ≤ 0.8 μm. To comply with 3-A guidelines, always provide a leakage hole of min. 2.38 mm (0.09 in) at the
lowest position.
When using soft or PTFE sealings, observe the instructions of the sealing manufacturer, particularly with regard to
■
tightening torque and load cycles.
G 1 hygienic
Wetted seals from EPDM or FKM
