Pressure Limits
See Table A-6, Table A-7, and Table A-8.
Vacuum Limits
PTFE Lining
Full vacuum to 350 °F (177 °C) through 4-in. (100 mm) line sizes. Consult
factory for vacuum applications with line sizes of 6 inches (150 mm) or
larger.
All Other Standard Sensor Lining Materials
Full vacuum to maximum material temperature limits for all available line
sizes.
Submergence Protection
(1)
IP68. Continuous submergence to 30 ft. (10 m) requires that conduit entries of
the sensor remote junction box be properly sealed to prevent water ingress.
This requires the user to install sealed IP68 approved cable glands, conduit
connections, or conduit plugs. For more details on proper installation
techniques for an IP68 / submersible application, reference Rosemount
Technical Document 00840-0100-4750 available on www.Rosemount.com.
Conductivity Limits
Process liquid must have a conductivity of 5 microsiemens/cm (5
micromhos/cm) or greater for 8705. Process liquid must have a conductivity of
50 microsiemens/cm (50 micromhos/cm) for 8707 when used with 8712H, 5
microsiemens/cm when used with other transmitters. Excludes the effect of
interconnecting cable length in remote mount transmitter installations.
