Rosemount 1151 Pressure Transmitter
Rosemount 1151 pressure transmitter
tatic Pressure Limits
Transmitters operate within specifications between the following
0.5 psia to 2,000 psig (3.45 kPa to 13790 kPa).
0.5 psia to 4,500 psig (3.45 kPa to 31027 kPa).
0 psia to the URL.
0.5 psia (3.45 kPa) to the URL.
Limit is 0.5 psia (3.45 kPa) to the flange rating or sensor rating, whichever is lower.
Transmitters withstand the following limits without damage:
0 psia to 2,000 psig (0 to 13790 kPa).
0 psia to 4,500 psig (0 to 31027 kPa).
0 psia to 2,000 psia (0 to 13790 kPa).
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).
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.
0 to 100% relative humidity
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.
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
Output Codes L, M
Damping is fixed at minimum time constant.
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.
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.
