Rosemount 1152
Rosemount 1152AP and 1152GP:
Static Pressure Zero Effect
Rosemount 1152DP
Per 2,000 psi (13.8 MPa)
Rosemount 1152HP:
Per 4,500 psi (31.0 MPa)
Static Pressure Span Effect
Effect is systematic and can be calibrated out for a particular pressure before
installation. Correction uncertainty is ±0.25% of input reading/1,000 psi
(6.89 MPa) (±0.5% of input reading/1,000 psi for Range Code 3).
Power Supply Effect
Less than 0.005% of output span/volt
Load Effect
No load effect other than the change in voltage supplied to the transmitter
Mounting Position Effect
No span effect; zero shift of up to 1 inH
2
O, which can be calibrated out
FUNCTIONAL
SPECIFICATIONS
Service
Liquid, gas, or vapor
Output
4–20 mA dc or 10–50 mA dc (seismic qualification only)
Power Supply
Design limits as shown in Figure 6-1 for 4–20 mA dc and 10–50 mA dc
Range Code Overpressure Effect
3, 4
2,000 psig (13.8 MPa) will cause a zero shift
of less than ±0.25% of upper range limit.
5–8
2,000 psig (13.8 MPa) will cause a zero shift
of less than ±1.0% of upper range limit.
9
4,500 psi (31.0 MPa) will cause a zero shift
of less than ±0.5% of upper range limit.
0
7,500 psi (51.7 MPa) will cause a zero shift
of less than ±1.0% of upper range limit.
Range Code Static Pressure Zero Effect
4, 5 ±0.25% of upper range limit
3, 6–8 ±0.5% of upper range limit
Range Code Static Pressure Zero Effect
all ±2.0% of upper range limit
