SENSOR ASSEMBLY
Using the sensor assembly, integrated in the instru-
ment package is the easiest implementation for a
single meter run; however, the standard application
program also allows use of external transmitters,
with or without the integrated sensor assembly.

Bristol’s DP/P Multivariable (MVT) Sensor Assembly
Most two-run systems use the integrated sensor
assembly for the rst run and an external, smart
multivariable transmitter, such as the Bristol 3808
MVT (which includes the exact same sensor assem-
bly), for the second meter run.
If the sensor assembly requires a repair, the user
can change it out and continue operating with the
electronics, including ow information, alarms and
historical archives, all intact.
Emerson recommends that users practice “depot
level” service, in other words, that the sensor as-
sembly be removed and replaced at the shop rather
than out at the site.
Each sensor assembly has a nine-digit part number,
which can be used to specify a replacement part
(a listing is included at the end of this product data
document).
