Specifications and Reference Data
Turn-On time
Performance within specifications less than 5 seconds for 3051SMV (typical) after power is
applied to the transmitter.
Volumetric displacement
Less than 0.005 in
3
(0,08 cm
3
)
Damping
Analog output response to a step change is user-selectable from 0 to 60 seconds for one time
constant. Each variable can be individually adjusted. This software damping is in addition to
sensor module response time.
Failure mode alarm
If self-diagnostics detect a gross transmitter failure, the analog signal will be driven offscale to
alert the user. Rosemount standard (default), NAMUR, and custom alarm levels are available
(see Tab le A -1 below).
High or low alarm signal is software-selectable or hardware-selectable via the optional switch
(option D1).
Table A-1. Alarm configuration
High Alarm Low Alarm
Default 21.75 mA 3.75 mA
NAMUR compliant
(1)
(1) Analog output levels are compliant with NAMUR recommendation NE 43, see option codes C4 or C5.
22.5 mA 3.6 mA
Custom levels
(2)
(2) Low alarm must be 0.1 mA less than low saturation and high alarm must be 0.1 mA greater than high
saturation.
20.2 - 23.0 mA 3.6 - 3.8 mA
