Rosemount 3095FB
A-2
User Interface Software and Hardware Requirements:
• IBM-compatible PC
• 10 MB of available hard drive space
• Microsoft
®
Windows
®
98 or higher operating system
• CD-ROM drive
• 32 MB of RAM
Temperature Limits
Process (at transmitter isolator flange for atmospheric pressures and above):
• –40 to 250 °F (–40 to 121 °C)
• Inert fill sensor: 0 to 185 °F (-18 to 85 °C).
• Process temperatures above 185 °F (85 °C) requires derating the ambient limits by a
1.5:1 ratio.
Ambient:
• –40 to 185 °F (–40 to 85 °C)
• with integral meter: -4 to 175 °F (-20 to 75 °C)
Storage:
• –50 to 212 °F (–46 to 100 °C)
• with integral meter: -40 to 185 °F (-40 to 85 °C)
Turn-on Time
Process variables will be within specifications less than 4 seconds after power is applied to
transmitter.
Damping (3095FB only)
Response to step input change can be user-selectable from 0.1 to 30 seconds for one time
constant. This is in addition to sensor response time of 0.2 seconds.
