Note!
For the DP71B and DP72B sensors, tighten the load nuts until the load plate is 0.050" (1.3
mm) from the indicator ring.
For the DP73B sensors, the load plate should be 0.063" (1.6 mm) from the indicator ring.
13. Thread on the three jam nuts and tighten until they are resting hand-tight against the lock nuts.
14. Place a backup wrench on the load nut to prevent it from rotating. While not allowing the load
nut to rotate.
15. Tighten the jam nuts 1/8 turn beyond hand-tight.
16. Tighten the three packing bolts to the appropriate torque value listed in the table below:
!
Note!
The weld on the weld ring should not contact the top surface of the follower. If the weld on the
weld ring comes into contact with the follower, the sensor will not be properly bottomed in the pipe.
If this occurs, consult the factory before proceeding.
3.8.1 Installation of the shut-off valves (for the remote version):
The shut-off valves have to be mounted to the nozzles of the primary element before mounting the
sensor into the pipe.
3.8.2 Installation of the manifold and the transmitter for the remote
version:
The impulse pipes have to be installed with the required slope.
(For liquids or steam:
→
ä
10, for gases:
→
ä
11).
• For steam and liquids, a venting possibility has to be provided at the highest point.
• For gases, a drainage has to be mounted at the lowest point. The impulse lines (+) and (-) have to
be mounted to the respective inlets (process connections) of the manifold.
The transmitter is directly screwed to the manifold with the supplied screws and gaskets.
