Rosemount 1151 Pressure Transmitter

Mar 21, 2016

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.
