Hazardous area (ATEX)
The CombiTemp™ TFRx can be supplied for hazardous area. Either
as a Simple Apparatus with RDT output or with built in transmitter
with 4 ... 20 mA output.
A CombiTemp™ TFRx with built in transmitter will have two possible
ATEX approvals, Ex ia (zone 0, 1 or 2) or Ex nA (zone 2).
II 1 G, EX ia IIC T4/T5, Gas
II 3 G, Ex nA IIC T4/T5, Gas
The remaining Ex parameters depend on the type of transmitter and
display selected for the product. See detailed data below.
The CombiTemp™ TFRx with Ex ia must be installed in accordance
with prevailing guidelines for zone 0 and zone1 and a certified intrin-
sically safe zener barrier with the listed maximum values must be
used. Electrical connection for the temperature transmitter as per
below diagram.
CombiTemp™ TFRx with Ex nA must be installed in accordance
with prevailing guidelines for zone 2 without a barrier.
