3.5.1 Install Rosemount
™
305 Integral Manifold
To install a Rosemount 305 Integral Manifold to a Rosemount 3051 Transmitter:
Procedure
1. Inspect the PTFE sensor module O-rings.
You may reuse undamaged O-rings. If the O-rings are damaged (if they have nicks
or cuts, for example), replace with O-rings designed for Rosemount transmitters.
Important
If replacing the O-rings, take care not to scratch or deface the O-ring grooves or the
surface of the isolating diaphragm while you remove the damaged O-rings.
2. Install the Integral Manifold on the sensor module. Use the four 2.25-in. manifold
bolts for alignment. Finger tighten the bolts; then tighten the bolts incrementally in
a cross pattern as seen in Figure 3-16 to final torque value.
See Flange bolts for complete bolt installation information and torque values. When
fully tightened, the bolts should extend through the top of the sensor
module housing.
