Pulse Generator
Productseries SP/SFE 30/3003
compliant with ATEX Directive 94/9/EC
for oil and grease lubrication systems
designed to consume 0,1 to 50 cm³/min
General remarks
Group SP/SFE 30/3003 pulse generators
are used to monitor oil and grease volumet-
ric flow rates of 0,1 to 50 cm³/min at a
maximum permissible operating pressure of
600 bars.
Group SP/SFE 30/3003 pulse generators
are mainly used on metal-forming machines
and for the lubrication of cylinders and
compressors.
The pulse generator, a mechanical device,
does not have any potential ignition source.
The built-in floating contact can be used as
a simple electrical device in intrinsically safe
circuits in accordance with DIN EN 60079-
11, Section 5.7.
The pulse generator can be used in zone 1
and 21 (intrinsically safe) with an Ex i
certificated electric power supply.
The limit values for the switching contact
can be found on page 3 in “Technical Data
=> Electrical System” and must not be
exceeded.
