The Dräger Polytron® 8310 IR is an advanced explosion proof transmitter for the detection of combustible gases in the lower explosion limit (LEL). It uses an infrared DrägerSensor® IR that can be configured for methane, propane or ethylene. Besides a 3 wire 4 to 20 mA analogue output with relays, it also offers Modbus and Fieldbus protocols making it compatible with most control systems.
• Poison-resistant and fail-safe – the DrägerSensor® IR
• Easy device management via digital communication
• 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
• Data logger
For the detection of combustible gases in the lower explosion limit (LEL). It uses an infrared DrägerSensor® IR that can be configured for methane, propane or ethylene. Besides a 3 wire 4 to 20 mA analogue output with relays, it also offers Modbus and Fieldbus protocols making it compatible with most control systems. Long life optics result in lower maintenance costs compared to pellistors. IR technology is inherently fail-safe, meaning no unrevealed failures.
