Fig. 5.3 – Backup Ring Mounting
Should the adapters (
26
) have been removed, it is recommended to replace gaskets (
24
) and to
connect the adapters to the process flanges before coupling them to the sensor. Optimum torque is
2,5 Kgfm.
The fitting of the sensor must be done with the main board out of the electronic housing. Mount the
sensor to the housing turning it clockwise until it stops. Then turn it counterclockwise until the cover
(
1
) is parallel to the process flange (
17
). Tighten the screw (
8
) to lock the body to the sensor.
ELECTRONIC CIRCUIT
Plug sensor connector and power supply connector to main board. If there is a display, attach it to the
main board by means of 4 screws (
3
). The display can be installed in any of the 4 possible
positions(See Fig. 5.4).
The ”

mark indicates up position.
Pass the screws (
5
) through the main board holes (
6
) and the spacers (
7
) as shown on Figure 5.1 and
tighten them to the body.
Fig. 5.4 – Four Possible Positions of the Display
After tightening the protective cover (
1
), mounting procedure is complete. The transmitter is ready to
be energized and tested. It is recommended that adjustment be done on the ZERO TRIM and on the
UPPER PRESSURE TRIM.
