Static Overpressure Limits
Transmitters withstand the following limits
without damage:
Model 3051CD Only
Operates within specifications between static line pressures of 0.5 psia
and 3626 psig (4500 psig for Option Code P9)
Range 0: 0.5 psia and 750 psig
Range 1 (Model CD): 0.5 psia and 2000 psig
Ranges 2–3 (Model PD): 0.5 psia and 2000 psig
For Model 3051L or Level Flange Option Codes FA, FB, FC, and FD,
limit is 0.5 psia to the flange rating or sensor rating, whichever is lower.
Burst Pressure Limits
Burst pressure on Coplanar or traditional process flange is 10000 psig
(689 bar)
Burst pressure for the Model 3051T is
Ranges 1–4:11000 psi (758 bar)
Range 5:26000 psig (1 793 bar)
Alarms
The AI block allows the user to configure HI-HI, HI, LO, or LO-LO
alarms, with a variety of priority levels.
