Hazardous area installations
If you are installing the sensor in a hazardous location, verify that the hazardous classification information
printed on the sensor tag matches the environment in which the sensor will be installed.
Failure to comply with the requirements for intrinsic safety in a hazardous area
could result in an explosion.
•
Make sure the hazardous area specified on the sensor approval tag (Figures 1–7)
is suitable for the environment in which the sensor will be installed.
•
For installations in an area that requires intrinsic safety, use this document along
with Micro Motion approval documentation, shipped with the sensor or available on
the Micro Motion web site at www.micromotion.com.
•
For hazardous installations in Europe, refer to standard EN 60079-14 if national
standards do not apply.
Failure to seal the sensor and transmitter housings could cause electronics to
be exposed to moisture, which could result in measurement error or flowmeter
failure.
•
Close and fully tighten all covers.
•
Ensure the integrity of gaskets and O-rings.
•
Grease all O-rings before sealing.
•
Install drip legs in cable or conduit.
•
Seal all conduit openings.
Installation options
The sensor has one of the following electronics configurations:
• A Model 1700/2700 or IFT9701 transmitter. No wiring is required between the sensor and the
transmitter. Skip to Grounding on page 21.
• A core processor to a 4-wire remote transmitter (requires 4-wire cable); see Core processor to a 4-wire
remote transmitter on page 18.
• A core processor to a remote host (requires 4-wire cable); refer to the Micro Motion MVD
™
Connect
Flowmeter Installation Manual.
• A junction box to a 9-wire remote transmitter (requires 9-wire cable); see Junction box to a 9-wire
remote transmitter or remote core processor on page 21.
