WIKA operating instructions temperature transmitter T32.xS
39
■
The external wiring shall be suitable for the ambient temperature
range of the end use application. The maximum ambient tempe-
rature for T32 of 85 °C shall be considered. The minimum cross
section for external wiring is 0.14 mm².
■
Ex ic applications:
The temperature transmitters model T32.xx.0NI shall be installed
in a pollution degree 2 environment or better in the end use appli-
cation for use with an IP 20 minimum enclosure provided by end
user.
■
Ex nA or nL applications:
The temperature transmitters model T32.xx.0NI shall be installed
in a pollution degree 2 environment or better in the end use appli-
cation for use with an IP 54 minimum enclosure provided by end
user.
Operation in zone 0:
The temperature transmitter may only be operated in areas requiring
category 1 equipment when the following atmospheric conditions
exist:
Temperature: -20 ... +60 °C
Pressure:
0.8 ... 1.1 bar
Operation in zone 1 and zone 2:
In accordance with the temperature class, these transmitters may
only be used in the following ambient temperature ranges:
