Transmitter Mounting Kits are normally containing:
Pressure Measurement: 2 Screws and 1 Seal Ring or 4 Screws and 1 Seal Ring
Differential Pressure Measurement: 4 Screws and 2 Seal Rings
The required bolt length results from manifold flange thickness b + min. required thread engagement at the instrument (9mm), but max. 14mm. Example: Manifold flange thickness 31.2mm (1.23″) + 9mm (0.35″), but max. 14mm (0.55″) = Min. 40.2mm (1.58″) and max. 45.2mm (1.78″). This results in a bolt length of 1 3/4″ (7/16-20 UNF screw) respectively 45mm (M10 screw).
When installing a Rosemount 2051/3051 Pressure Transmitters with CoplanarTM Flange, longer bolts are required: Flange thickness b (for example again 31.2mm) + min. 44.5mm (1 3/4″) and max. 48mm (1.89″) results in a bolt length of 3″ (76.2mm) – min. 75,7mm (2.98″) and max. 79.2mm (3.12″). Washers are required for Traditional Style Manifolds types H & T, because the bolt holes are slotted. The washer thickness is 1.5mm (0.06″). This needs to be considered when calculating the bolt length.
Available seal ring materials are: PTFE, Graphite and FKM (O-Ring)
