2.5 O-rings

The two styles of Rosemount flange adapters (Rosemount 1151 and
Rosemount 3051/2051/2024/3095) each require a unique O-ring (see

Figure 2-3). Use only the O-ring designed for the corresponding flange

adapter.

WARNING

Failure to install proper flange adapter O-rings may cause process leaks,
which can result in death or serious injury. The two flange adapters are
distinguished by unique O-ring grooves. Only use the O-ring that is designed
for its specific flange adapter, as shown below. When compressed, PTFE O­rings tend to cold flow, which aids in their sealing capabilities.

7 Trim the transmitter

Devices are calibrated by the factory. Once installed, it is recommended to
perform a zero trim on gage transmitters to eliminate error due to mounting
position or static pressure effects. A zero trim can be performed using either
a Field Communicator or configuration buttons.

Note

When performing a zero trim, ensure the equalization valve is open and all
wet legs are filled to the correct level.

CAUTION

It is not recommended to zero an absolute transmitter, Rosemount
2051HTA model.

Procedure

Choose your trim procedure.

a) Analog zero trim – Sets the analog output to 4 mA.

b) Also referred to as a “rerange,” it sets the lower range value (LRV)

equal to the measured pressure.

c) The display and digital HART output remains unchanged.

d) Digital zero trim – Recalibrates the sensor zero.

e) The LRV is unaffected. The pressure value will be zero (on display and

HART output). 4 mA point may not be at zero.

f) This requires the factory calibrated zero pressure is within a range of

3% of the URV [0 ± 3% x URV].

Example

URV = 250 inH2O Applied Zero Pressure = ± 0.03 x 250 inH2O = ± 7.5 inH2O
(compared to factory settings) values outside this range will be rejected by
the transmitter
