General information
CROUZET intrinsically safe pressure switches conform to
European Standards EN 50014 and EN50020 relating to equipment
operating in potentially explosive atmospheres.
These intrinsically safe products are recommended for the
chemical, petro-chemical, gas and mining industries, etc.
These intrinsically safe pressure switches must be individually
connected to an approved safety barrier. Placed in a safe zone,
these safety barriers make it possible to supply intrinsically safe
pressure switches installed in a hazardous zone.
1 = common
2 = NC contact
4 = NO contact
The electrical connection between the safety barrier (or interface) and
the pressure switch can be made with ordinary wires or cables.
The maximum intrinsically safe supply voltage must not exceed 60V.
Recommended barriers and interfaces
These CROUZET recommended safety barriers and interfaces can be obtained from the manufacturers indicated below. Specify when ordering that
they are to be used to supply intrinsically safe pressure switches (type 81 513) EEx ia II C T6, LCIE no. 93.C6015 X.
