THE BARRIER AMPLIFIER Mk 13-P-Ex 0 / 24
VDc / k15
The barrier amplifier MK 13-P-Ex 0/24 VDC/K15 enables
a galvanic isolated transmission of binary switching
status. It has an intrinsically safe control circuit and is
certified according to II(1) GD (EExial) IIC.
There is a galvanic separation from the control circuit
to the output circuit and to the power supply. For the
transmission of two channels, two barrier amplifiers of
this version are necessary. The control circuit can be
monitored concerning wire breaking and short circuit (the
monitoring can be switched off via a wire jumper).
An error in the control circuit stops the signal output but
is not displayed as an error message. Two plus-switching
short circuit proof transistor outputs (PNP-outputs) display
the digital signal of a channel antivalently.

STAUFF FLOW METERS IN Ex-DESIgN
STAUFF flow meters of the SGF-series in Ex-design
are approved for applications in potentially explosion-
hazardous areas and are always operated in conjunction
with one or two barrier amplifiers. They have blue mar-
kings and offer the necessary Ex-protection security. The
type plate shows the necessary description according to
DIN EN 50014, the type key and the safety-related and
electric data. STAUFF can supply flow meters with the
barrier amplifiers type MK 13-P-Ex 0/24 VDC/K15.

The pick-up system consists of one or
two sensor units which are screwed into
the cover of the SGF flowmeter and of a
downstream switched amplifier.This
amplifier is connected with the flowme-
ter by means of a temperatureresistant
cable and has to be installed outside the
high temperature area.ere the ambient
temperature should not be higher than
50°C.
Depending on the amplifier version
the digital signals are output as PNP or
NPN switching signals.
The following pictures show the respec-
tive connection of the electrinic readout:
1 : supply +U = 10 ...30V
2 : digital signal
3 : supply -U = 0 V
4 : none

For long cable lenghts and high input
impedance it is recommended to use
shielded cables and pull down (PNP-sig-
nal) or pull up (NPN-signal) resistor.
