A-8
Rosemount 1151GP
Ranges 3–8: 0 psia to 2,000 psig (0 to 13790 kPa).
Range 9: 0 psia to 4,500 psig (31027 kPa).
Range 0: 0 psia to 7,500 psig (51710 kPa).
Rosemount 1151LT
Limit is 0 psia to the flange rating or sensor rating, whichever is lower. See
Table A-5.
Burst Pressure Limit
All models: 10,000 psig (68.95 MPa) burst pressure on the flanges.
Humidity Limits
0 to 100% relative humidity.
Volumetric Displacement
Less than 0.01 in
3
(0.16 cm
3
).
Failure Mode Alarm (Smart only)
When not in multidrop mode, self-diagnosis detects a gross transmitter
failure, the analog signal will be driven below 3.9 mA or above 21 mA to alert
the user. High or low alarm signal is user selectable.
Transmitter Security (Smart only)
Activating the transmitter security function prevents changes to the transmitter
configuration, including local zero and span adjustments. Security is activated
by an internal switch.
Overpressure Alarm (Smart only)
If the sensor detects a negative overpressure value, the analog signal will be
driven to 3.9 mA. If the sensor detects a positive overpressure value, the
analog signal is driven to 20.8 mA.
Damping
Numbers given are for silicone fill fluid at room temperature. The minimum
time constant is 0.2 seconds (0.4 seconds for Range 3).
Inert-filled sensor values would be slightly higher.
