The Drager Polytron Pulsar 2 is a fixed gas open path detector for flammable gases using a transmitter and receiver. The infra red beam is transmitted to the receiver and the gas reading is determined by the resulting IR absorption signal loss.  Explosion proof it can be used in hazardous zone areas.  As standard it detects Methane or Propane as selected by user, range from 0 to 4 up to 0 to 8 LEL m.  Dependent on the area being monitored a range of different transmitters are provided reflecting the distance between transmitter and receiver. 4 to 60 m, 30 to 120 m or 100 to 200 m, (13 to 197 ft, 98 to 394 ft or 328 to 656 ft).

To align to the transmitter and receiver correctly an alignment kit containing a hand held terminal, test cards and software is available. Once aligned automated zeroing of gas completes to finalise the install. Manual aligning or gas testing is not required. Fault detection is diagnosed by the 4-20mA output variation. Under 1mA out means the beam is blocked or hardware fault.  2mA identifies a recent beam block which will fault if blockage time exceeds one hour. A 3.5mA output indicates misalignment or dirt interference, a pre-warning signal to schedule maintenance, monitoring will still be operational.

The receiver logs gas readings, signal strength/blocks and temperature for up to a week. A condensed version is stored for up to a month. To insure system integrity the Drager Polytron Pulsar 2 adapts to changing environmental conditions to maintain accuracy. Heated optics combat the cold. The receiver instructs the transmitter digitally to increase the flash rate in the wake of interference or on the detection of gas. The detector is resistant to sunlight so can be used in the desert, also immune to flare stacks so it is ideal for oil and gas applications.

Hart communication allows digital access to the Pulsar outside hazardous areas.
