The Drager Polytron 5100 EC is an explosion-proof transmitter for toxic gases or oxygen monitoring continuously. Accepting plug and play electrochemical sensors (EC). Sensors are pre-calibrated for fast installation and have broad temperature capability (-40°C to +65°C). Sensor connection is intrinsically safe, allowing swapping without area declassification. The transmitter can connect with a remote sensor without running conduit; for this option, 30 metres of cabling are included.

As part of the 5000 family, the Polytron 5100 has the same interface allowing familiarity of operation based universal design, making training and maintenance more efficient in time and cost.  Non-intrusive access to the detector menus is possible using a magnetic wand. With three-wire power, the display is backlight four-digit, nine segments.  Measurements are shown with units, status indication via coloured LEDs (green, yellow and red) and warning messages.

Versions are available equipped with three integrated relays to enable operation as an independent gas detection system.  Two configurable gas concentration alarms and one fault alarm, allowing activation of visible or audible warning devices without cabling to a central controller.

Enhanced Safety (e) version includes a docking station assisting installation in hazardous areas without the need for conduit (where agreed). There are two choices of housing, epoxy coated copper-free aluminium or stainless steel, for aggressive environments.

  • Power supply three-wire (10 to 30 Vdc) or two-wire (18 to 30 Vdc)
  • Output 4-20mA  two or three-wire
  • Approvals; ATEX, UL, CSA & IECEx
