Reference Manual

00809-0100-4027, Rev AA December 2005

Overpressure Limits

Transmitters withstand the following pressure without damage: Range 1: 150 psi (10.34 bar)

Range 2: 300 psi (20.68 bar)

Burst Pressure Limits

Range 1: 300 psi (20.68 bar)

Range 2: 450 psi (31.02 bar)

Temperature Limits

Ambient

32 to 140 °F (0 to 60 °C)

Storage

–22 to 185 °F (–30 to 85 °C)

Process Temperature Limits

32 to 400°F (0 to 204°C)

Horizontal Mount

For process temperatures above 293°F (145°C), derate ambient temperature by 7°F (4°C) for every 18°F (10°C) increase in process temperature.

Top Mount

For process temperatures above 266°F (130°C), derate ambient temperature by 9°F (5°C) for every 18°F (10°C) increase in process temperature.

Vacuum Application

Process vacuums in excess of 200 mmHg requires derating process temperature to 212°F (100°C).

Turn-On Time

Performance within specifications less than 2.0 seconds after power is applied to the transmitter

Damping

Analog output response to a step input change is user-selectable from 0 to 60 seconds for one time constant. This software damping is in addition to sensor module response time.

Failure Mode Alarm

HART 4-20mA (output code A)

If self-diagnostics detect a gross transmitter failure, the analog signal will be driven offscale to alert the user. Rosemount standard and custom alarm levels are available.

High or low alarm signal is software-selectable.
