Drager 8344404 Polytron 8100 EC d A 4-20 HART Relay Gas Transmitter

Drager 8344404 Polytron 8100 EC d A 4-20 HART Relay Gas Transmitter

-----

The Drager 8344404 Polytron 8100 EC d A 4-20 HART Relay Gas Transmitter is an explosion-proof fixed gas transmitter designed for detecting toxic gases and oxygen in industrial environments. It uses a high-performance, plug-and-play electrochemical DragerSensor to provide continuous gas monitoring. The transmitter features a 3-wire 4–20 mA analog output and HART communication, making it suitable for integration with compatible gas monitoring and control systems.

The Polytron 8100 EC is designed for demanding industrial applications, including facilities where hazardous gases need to be monitored continuously. Its intelligent sensor technology supports reliable detection, while the backlit graphic display and coloured status LEDs provide clear operating and alarm information. The transmitter also includes a built-in data logger for recording gas readings and events, supporting maintenance and operational monitoring.

The Drager 8344404 version comes with an aluminium explosion-proof enclosure and three integrated relays: two alarm relays and one fault relay. These relays can be used to operate compatible external equipment, such as audible alarms and signal lights. With its robust construction, electrochemical sensing technology and digital communication capabilities, the Polytron 8100 EC supports fixed gas detection requirements across industrial and hazardous-area applications.
