Feature description

®
Polytron 8xx0 instruments are housed in a rugged stainless
steel or aluminum enclosure for indoor and outdoor
applications.
There are 3 main versions of the Polytron
®
– Polytron 8100 EC is intended for electrochemical
sensors (EC sensors).
®
– Polytron 8200 CAT / Polytron
catalytic Ex sensors (CatEx sensors) and infrared Ex
sensors (IREx sensors).
®
– Polytron 87x0 IR is intended for PIR 7x00 sensors.
Gas concentrations, status messages, and menu choices are
displayed on a backlit graphic LC-display and 3 colored LEDs.
With the non-relay version the red LED flashes to inform
visually and no relay is energized. To energize the A1 or A2
relay the optional relay board must be installed.
Navigation through the menu is done by taping a magnetic
wand on the glass at the appropriate indicator. The instrument
can be configured, calibrated and maintained non-intrusively
without declassifying the area.
The instrument can be operated as current source or sink.
The instrument come with a data logger. For information on
how to handle the data logger, see the technical manual.
The data logger can store up to 35000 values. At a sampling
interval of 1 measurement per minute the data logger stores
the measurement history of approximately 24 days. This time
can be significantly increased if the trigger function is enabled.
The data logger can only be downloaded using the PolySoft
PC software.

3.3.3 Explosion protection

®
The Polytron 8xx0 instruments are available in 2 explosion
protection types.
● Explosion proof instrument (Ex d)
The flameproof / explosion proof enclosure provides three
¾" NPT openings, which can be used for field wiring,
direct attachment of a sensor or wiring of a remote sensor.
● Instrument for increased safety (Ex e)
The instrument is extended by an increased safety
terminal box (docking station) that provides up to four 20
mm openings, which can be used for field wiring or wiring
of a remote sensor. The permissible cable diameter range
is 7 to 12 mm.

Intended use

The instruments of the Polytron
continuous monitoring of the ambient air.
With the optionally integrated relay module, the instrument
can be operated without a control unit (with additional local
alarm signaling).
With a sealed conduit or approved cable gland, the instrument
can be connected to a Dräger control unit or a Programmable
Logic Controller (PLC).
If the 4 - 20 mA interface is used, the current between 0 and
3.5 mA must be monitored. Currents between 0 and 3.5 mA
can indicate a special state.
The instrument is designed to be installed in permanent
locations and is approved for use in hazardous, classified
areas.
®
Polytron 8100 EC-specific:
®
– Polytron 8100 EC is a combined intrinsically safe /
explosion proof instrument for continuous monitoring of
toxic gases or oxygen in the ambient air.
®
Polytron 8200 CAT-specific:
®
– Polytron 8200 CAT with catalytic DrägerSensor DQ or LC
is an explosion proof instrument for the continuous
monitoring of combustible gases and vapors containing
hydrocarbons and non-hydrocarbons (e.g. hydrogen or
ammonia) in ambient air.
