– The capacitance and inductance of the connecting
cable has to be considered.
– The O
be used in / with the fittings InFit 76*-*** or
InTrac 7**-***, or in / with other suitable fittings
in potentially explosive areas.
– The metal body of the O
fittings InFit 76*-*** or InTrac 7**-***, or other
appropriate fitting is optionally included in the
routine pressure test of the system.
– The independent fitting used for installation of O
Oxygen sensor must be conductively connected to
the equipotential bonding system.
