Instructions specific to hazardous area installations (I3)
The 2130N*** Vibrating Fork Liquid Level Sensor (hereinafter,
Level Switch in this section), manufactured by Rosemount
Measurement Limited, Emerson Automated Solutions Asia Pacific
Pte Ltd., and Rosemount Inc., has been certified by the National
Supervision and Inspection Center for Explosion Protection and
Safety of Instrumentation (NEPSI). The Level Switch accords with
GB 3836.1-2000 and GB 3836.4-2000 standards.
Ex marking: Ex ia IIC T5~T2
Certificate: GYJ101372X
Special conditions for safe use:
1. The "X" in the certificate number denotes specific conditions
of use:
a. When the Level Switch is used with process mediums
in excess of 80 °C, then the internal electronics
temperature shall not exceed this value.
b. The metallic alloy used for the enclosure material may
generate a spark if it is subject to friction or an
impact.
c. To avoid an electrostatic charge, the non-metallic
parts incorporated in the Level Switch enclosure shall
only be cleaned with a damp cloth.
2. The relationship between temperature class, ambient
temperature range, and process temperature range is as
follows:

3. Safety parameters:
Ui:15 V, Ii:32 mA, Pi:100 mW, Ci:12 nF, Li:60 μH
4. The Level Switch should be used with Ex-certified associated
apparatus to establish an explosion protection system that
can be used in explosive gas atmospheres. Wiring and
terminal connections should comply with instructions in the
manuals of the Level Switch and associated apparatus.
5. The cables between the Level Switch and associated
apparatus should be shielded (screened). The cable screen
has to be grounded reliably in a non-hazardous area.
6. Associated apparatus should be installed in a safe location.
During installation, operation, and maintenance, the
instruction manual should be strictly observed.
7. End users are not permitted to change any components
inside. (See "Product recycling and disposal" on page 5
contact information).
8. During installation, use, and maintenance of the Level
Switch, the following standards are to be observed:
a. GB3836.13-1997
"Electrical apparatus for explosive gas atmosphere
Part 13: Repair and overhaul for apparatus used in
explosive gas atmosphere".
b. GB3836.15-2000
"Electrical apparatus for explosive gas atmosphere
Part 15: Electrical installations in hazardous area
(other than mines)".
c. GB3836.16-2006
"Electrical apparatus for explosive gas atmosphere
Part 16: Inspection and maintenance of electrical
installation (other than mines)".
d. GB50257-1996
"Code for construction and acceptance of electric
device for explosion atmospheres and fire hazard
electrical equipment installation engineering".
