Rosemount 1151 Pressure Transmitter

Rosemount 1151 pressure transmitter

 

tatic Pressure Limits


Transmitters operate within specifications between the following
limits:


Rosemount 1151DP
0.5 psia to 2,000 psig (3.45 kPa to 13790 kPa).


Rosemount 1151HP
0.5 psia to 4,500 psig (3.45 kPa to 31027 kPa).


Rosemount 1151AP
0 psia to the URL.


Rosemount 1151GP
0.5 psia (3.45 kPa) to the URL.

Rosemount 1151LT
Limit is 0.5 psia (3.45 kPa) to the flange rating or sensor rating,


whichever is lower.


Overpressure Limits


Transmitters withstand the following limits without damage:
Rosemount 1151DP
0 psia to 2,000 psig (0 to 13790 kPa).
Rosemount 1151HP
0 psia to 4,500 psig (0 to 31027 kPa).
Rosemount 1151AP
0 psia to 2,000 psia (0 to 13790 kPa).
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 4.
Burst Pressure All Models
10,000 psig (68.95 MPa) proof pressure on the flanges.


Humidity Limits


0 to 100% relative humidity
Volumetric Displacement
Less than 0.01 in3 (0.16 cm3)
Failure Mode Alarm (Output Code S)
If 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.


Overpressure Saturation Value (Output Code S)
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.


Transmitter Security (Output Code S)
Activating the transmitter security function prevents changes to the
transmitter configuration, including local zero and span
adjustments. Security is activated by an internal switch.
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.


Output Code S
Time constant is adjustable in 0.1 second increments from
minimum to 16.0 seconds.
Output Codes E and G
Time constant continuously adjustable between minimum and
1.67 seconds.


Output Codes L, M
Damping is fixed at minimum time constant.
1151LT
Time constant continuously adjustable between 0.4 and 2.2
seconds with silicone oil fill, or 1.1 and 2.7 seconds with inert
fill for flush models and electronics codes E or G.

Turn-on Time
Maximum of 2.0 seconds with minimum damping. Low power
output is within 0.2% of steady state value within 200 ms after
application of power.
