PC software. The download generates an .ofb file and a .txt
file. The .txt file includes the data logger information in
readable form.
The instruments can be connected to a Dräger controller or a
programmable logic control (PLC) with a sealed conduit or
approved cable gland.
The instruments can be operated as a current source or
current sink if the power is supplied by the controller. If the
instruments are connected to a separate power supply, they
can only operate as a current source.
The enclosures of the instruments are made of sturdy
stainless steel or aluminum, and are suitable for indoor and
outdoor application.
The instruments are designed for stationary installation. They
are available in the following designs:
– Explosion-proof instrument (Ex d)
The flameproof, explosion-proof enclosure provides three
¾ " NPT connections which can be used for field wiring,
direct connection of a sensor, or wiring of a remote sensor.
– Instrument for increased safety (Ex e)
The instrument is supplemented by an increased safety
terminal box (docking station) providing up to four 20 mm
connections for field wiring or wiring of a remote sensor. If
the cable gland from Dräger is used, the permissible cable
diameter is 7 mm to 12 mm.
The following dongles are available for the Polytron 8100 EC:
Sensor-test dongle
Diagnostic dongle
3.3 Intended use
The instruments in the Polytron 8000 family are intended for
continuous monitoring of the ambient air.
With the optionally integrated relay module, the instrument
can be operated without a central controller (with additional
local alarm signaling).
The instrument can be connected to a Dräger controller or a
programmable logic control (PLC) with a sealed conduit or
approved cable gland.
If the 4-20 mA interface is used, the current between 0 mA
and 3.5 mA must be monitored. Currents between 0 mA and
3.5 mA can indicate a special state.
The instruments are designed for permanent installation and
are approved for use in hazardous areas.
– Polytron 8100 EC is a combined intrinsically
safe/explosion proof instrument for continuous monitoring
of toxic gases or oxygen in the ambient air.

Instructions for use
– Polytron 8200 CAT with catalytic DrägerSensor DQ or LC
is an explosion-proof instrument for continuous monitoring
of combustible gases and vapors containing hydrocarbons
and non-hydrocarbons (e.g., hydrogen or ammonia) in
ambient air.
– Polytron 8310 IR with infrared DrägerSensor IR is an
explosion-proof instrument for continuous monitoring of
combustible gases and vapors containing hydrocarbons in
ambient air.
– Polytron 8700 IR with PIR 7000 is an explosion proof
instrument for the continuous monitoring of combustible
gases and vapors containing hydrocarbons in an
appropriate atmosphere.
– Polytron 8720 IR with PIR 7200 is an explosion proof
instrument for the continuous monitoring of carbon dioxide
in ambient air.
3.4 Approvals

4.1.1 Mechanical installation
4.1.1.1 General information on mechanical installation
– Local, state, and national rules and regulations that
govern the installation of gas monitoring equipment must
be strictly observed.
– The physical properties of the gas or vapor to be detected
and the details of the corresponding application (e.g.,
possible leaks, air movement/drafts, etc.) must be taken
into account.
– The future use of accessories and maintenance
equipment must be considered.
– The free gas or vapor flow to the sensor must not be
obstructed.
– The instrument must not be exposed to radiant heat that
will cause the temperature to rise beyond the indicated
limit values (16.6 Environmental parameters). The use of
a reflective shield is recommended.
– A dust cap may be attached to the cable entry of the
instrument. This cap is neither explosion-proof nor
watertight and must be removed before connecting the
instrument to a sealed conduit or before installation of a
flameproof cable gland.
