Figure 2-4: Response Time vs. Total Performance Example
Note
Calculations conducted using Instrument Toolkit.
Parameters: Silicone 200 fill fluid, Rosemount 3051CD2 Transmitter, 15 ft. capillary
length, 2-in. FFW Seal, and calibrated at 25 °C.

Balanced vs. Tuned-System assemblies
A balanced remote seal system is a symmetrical system that utilizes equal seals and
capillary length on the high and low pressure sides of the transmitter. Since the capillary
lengths are the same, each side ideally has the same amount of fill fluid, minimizing or
completely eliminating the seal temperature effect due to equal pressure on both sides of
the transmitter diaphragm. The balanced systems are still affected by the head pressure as
shown in
.
