This product is now obsolete and has been replaced by the Polytron 8000.
The Polytron 2 XP Tox is an explosion proof gas detector for continuous monitoring of toxic
gases and Oxygen in ambient air. The transmitter converts the signal from an electrochemical
sensor to a 4 to 20 mA analog or HART or RS 485 digital signal output. The unit is
designed for one-man calibration, and offers a variety of diagnostics and self test features.
The configuration and calibration of the transmitter is menu guided and easy to perform,
using either the infrared remote control, the built-in push buttons, or a HART hand held
terminal. With the optional relays, Polytron 2 XP Tox can be operated as ‘stand alone’ unit.
Easy to install -
The enclosure provides two mounting
holes. For easy wiring, the electronics is
enclosed in a ‘bucket’, and can be pulled
out as one unit, held by a tether. The three
wire cable, fed through a sealed conduit, is
terminated in a pluggable connector at the
printed circuit board.
DragerSensor technology -
High sensitivity, long term stability and no
false alarms are the hallmark of the new
and improved third generation of sensors.
Sensors are the keystones of any gas
detection system. Fastest response to the target gas combined with minimal interference
by other gases or environmental
influences (no false alarms) as well as the
sensor life-time determine the reliability
and the operating cost of a system.
One man calibration -
All setup and maintenance can be performed
without opening the transmitter or
declassifying the hazardous area. An
infrared remote control, beaming through
the window, gives full access to the menu
and calibration procedure. The menu can
also be accessed using the built-in push
buttons or a HART hand held terminal. All
menu items and messages are displayed in
plain English. Other, user selectable languages
are French, Spanish and German.
Stand alone system -
With the three built-in relays, Polytron 2
XP Tox can be used as an independent
stand alone unit. Two adjustable gas alarm
levels and a fault alarm make it convenient
to switch warning devices on-site, without
having to run cables back and forth to a
central controller. The sensor signal can
still be transmitted using either the 4 to
20 mA, HART or RS 485 signal output.
