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 analogue output with relays makes it compatible with most control systems.

The DrägerSensor® ... DQ detects flammable gases and vapours such as hydrogen. Due to the double-detector compensation method, the catalytic sensor is particularly long-term stable. The wire mesh at the gas inlet serves as a flame barrier. So it ensures explosion protection at the same time short response time.

The Dräger VarioGard® 3200 CAT is a digital transmitter with an integrated catalytic DrägerSensor®. It detects the flamable gases methane and LPG in the ambient air. This affordable system component makes it easier for you to configure a gas warning system.

The Dräger PEX 1000 is a converter module that converts the mV signals of the Dräger Polytron® SE Ex sensing heads into mA signals and sends them to a control unit like the Dräger REGARD® family. Together with the Dräger Polytron® SE Ex, the PEX 1000 fulfils the conditions set down for primary explosion protection.
