Smart Transmitter Attachment for Differential Pressure Assembly

Balanced System: A complete assembly with one part number that includes two diaphragm seals, two capillaries, two fills, and one complete assembly calibration certificate.
RR-assembly Code: RR Identical system on HP and LP Sides, capillary exit through process connections. Capillary mounts only.
RA-assembly Code: RA Identical system on HP and LP sides, capillary exit through face of cover flange. Capillary mounts only.
How To Order: Add the appropriate option code to the end of a diaphragm seal part number. Example: W9FFWR31S-B10-AS-RR

 

Unbalanced DP System: Where seal, mount, capillary, or fill is not identical. A complete assembly includes one diaphragm seal on the HP side AND one diaphragm seal on the LP side.
Code: RH (High Pressure Side) Mount via Process Connections
Code: RB (High Pressure Side) Mount via Face of Cover Flange
RL-assembly Code: RL (Low Pressure Side) Mount via Process Connections
Code: RC (Low Pressure Side) Mount via Face of Cover Flange
How to Order: Add the appropriate option code to the end of a diaphragm seal part number. An unbalanced system will require two separate part numbers, one for the HP side and one for the LP side. Ex:  (High Side Seal) W9FFWR31S-DTD-AS-RB  (Low Side Seal) W9FFWR31S-B10-AS-RL

 

Smart Transmitter Attachment for Gauge Pressure Assembly

In Line Pressure Transmitter
Code: R1 Mount to In-Line Gauge Pressure Transmitter. Direct or remote mount.
Code: R4 Horizontal Mount (Tank Mount) to In-Line Gauge Pressure Transmitter. Direct mount only.
How To Order: Add the appropriate option code to the end of a diaphragm seal part number. Example: W9FFWR31S-B10-AS-R1

 

Traditional Mount for Gauge Pressure: Seal mount on one side only, other side is vented.
Code: R2 Instrument mount through process connections, HP Side. Use “R3” if mounting to LP side
Code: R8 Instrument mount through face of cover flange, HP Side. Use “R9” if mounting to LP Side
How To Order: Add the appropriate option code to the end of a diaphragm seal part number. Example: W9FFWR31S-B10-AS-R2
