Sensors for use in hazardous
areas
|
 |
Many of the EGE flow sensors are
approved for use in hazardous areas. Units are available
for use in both Zone 1 and Zone 0 areas. Only sensors for which a certificate
of conformity
has been issued by the PTB can be used in Zone 0. The sensor and the corresponding
amplifier must be approved as a functional unit. Switching amplifiers that
are not mentioned
on the certificate must not be used. Our experts can advise you on the correct
choice. If
sensors, or sensor cables need to be outdoors, a lightning protection unit
must be installed.
This accessory is inserted into the sensor line, between the sensor and
the switching
amplifier. It limits lightning-induced voltages on the sensor line and diverts
them to earth.
Intrinsically safe switching amplifiers have galvanic separation between
the intrinsically safe
and non intrinsically safe zones. The switching amplifier must always be
mounted in the safe
area.
