The Dräger Polytron® 5310 IR is a cost effective explosion proof transmitter for the detection of flammable gases in the lower explosion limit (LEL). It uses an infrared DrägerSensor® IR that can be configured for methane, propane, or ethylene. A 3 wire 4 to 20 mA analog output with relays makes it compatible with most control systems.
• Poison-resistant and fail-safe – the DrägerSensor IR
• Same design, same operating principle
• Three relays for controlling external equipment
• Safe, robust housing for every application
• Make the impossible possible with the remote sensor
For the detection of flammable gases in the lower explosion limit (LEL). It uses an infrared DrägerSensor® IR that can be configured for methane, propane, or ethylene. A 3 wire 4 to 20 mA analog output with relays makes it compatible with most control systems. It is poison-resistant against chemicals that can shorten a catalytic bead pellistor’s life. Long life optics result in lower maintenance costs compared to pellistors. IR technology is inherently fail-safe, meaning no unrevealed failures.
