CSA Installations
The Scanner 3100 is CSA-certied as explosion-proof for Class I, Division 1, Groups C and D hazardous locations.
Wiring Precautions
CAUTION All eld wiring must conform to the National Electrical Code, NFPA 70, Article 501-4(b) for installa-
tions within the United States or the Canadian Electric Code for installations within Canada. Local
wiring ordinances may also apply. The cable used between the Scanner 3100 and other devices
must be either armored MC-HL cable or standard cable routed through conduit. If standard cable is
used, a conduit seal must be installed within 6 inches of the Scanner.
Pressure Precautions
!
WARNING: Before connecting the Scanner 3100 to a ow line, consider the pressure rating of the sensor
and the presence of harmful gases. The tubing and xtures used to connect the sensor to the manifold
in the ow line must be manufactured from materials that are appropriate for the pressure ratings of the
sensor used. If H2S is present, use a NACE sensor and take appropriate precautions to avoid exposure to
this hazardous gas.

B7 and B7M alloy steel is susceptible to rust. Other materials may be preferred for offshore use.
2
316 SS bolts have a CRN safe working pressure limit of 2725 psi.
3
5300-psi ranges require transducer code HP and have a CRN safe working pressure limit of 3625
psi. Single seal is limited to 3000 psi.
4
5300-psi ranges require transducer code HP and are not available with a Canadian CRN. 5300-psi
range has a CRN SWP limit of 3710 psi. Therefore, it is possible to measure to 3710 psi and remain
in CRN compliance. Single seal is limited to 3000 psi.
Note A four-port MVT adapter has been evaluated by CSA for use with the Scanner 3100 but is not released for pro-
duction at this time. Seals must be installed at each port for CSA compliance. The four-port MVT adapter has not
been evaluated for ATEX approval.
