2.4 Intrinsically Safe (IS) Barriers
The purpose of the intrinsically safe barriers is to provide protection based on
restriction of electrical energy within the apparatus and interconnecting wiring
exposed to a potentially explosive atmosphere to a level below that which can
cause ignition by either sparking or heating effects.
If the ViscoSite
TRANSDUCER
is to be installed in a Class 1 Division 1 area, the
transmitter and safety barriers must be installed
outside
the Class 1 Division 1
area unless additional safety measures are taken.
If required for your installation, the intrinsically safe barriers are installed within
the ViscoSite transmitter enclosure and pre-wired to the transmitter
motherboard as part of the initial configuration.
Typical IS barriers are shown in Figure 2.3.

System calibration is performed with the IS barriers installed.
If an intrinsically safe barrier needs to be replaced for any reason, the entire
system will require recalibration.
