Selection Item Descriptions and
Specications
Emerson’s Bristol Sensor Assembly
The sensor assembly is Selection “ABC” in the
model specication, e.g. “022” for the 100 psi gauge
pressure sensor or "142" for a 300" DP/2000 psig
static pressure multivariable sensor assembly.
Using the integral sensor assembly is the easiest
implementation for a single meter run; however, the
standard application program also allows use of
external transmitters.
Multiple-run systems can use the integral sensor
assembly for the rst run and an external, smart
multivariable transmitter, such as the Bristol 3808
MVT from Emerson(which includes the exact same
sensor assembly), for additional meter runs.
If the sensor assembly requires a repair, the user

can change it out and continue operating with the
"top end" 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 user’s 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
(please refer to the last page of this product data).

– Gauge Pressure or Differential Pressure/
Static Pressure
Combined effects of nonlinearity,
nonrepeatability and hysteresis at reference
pressure and over the operating temperature
range: GP, DP and SP linear mode: ±0.075% of
Calibrated Span or 0.015% of URL, whichever
is greater.
Temperature effect on Static and Differential
