Dräger Polytron 5100 EC, Detector for toxic gases and oxygen

The Dräger Polytron 5100 EC is a cost-effective explosion-proof
transmitter for the detection of toxic gases or oxygen in standard applications. It uses a high performance plug-and-play electrochemical DrägerSensor to detect a specific gas. A 2- or 3-wire 4 to 20 mA output with relays makes it compatible with most control systems.

With the unique electrochemical Dräger sensors, the Polytron 5100 covers a total of 15 typical gases in various
measuring ranges. These long-life sensors provide continuous detection even under the harshest conditions.
Dräger Sensors offer the industrys widest temperature range between -40 °C to +65 °C (-40 °F to +150 °F). The built-in memory contains all the necessary calibration and configuration information. The sensors are calibrated ready for immediate operation. The sensor's intrinsically safe connection dispenses with the need for a flame arrestor giving you a faster response time and higher sensitivity.

Polytron 5100 belongs to the Dräger Polytron 5000 series. All transmitters in this series have the same design and user interface. This allows for uniform operation with reduced training and maintenance requirements. The backlit display shows status information clearly with quick access to functions using a non-intrusive magnetic wand. The gas concentration and measurement unit are displayed during normal operation. Coloured LEDs (green, yellow and red) provide additional alarm and status information.

The Dräger Polytron 5100 can also be supplied with three integrated relays upon request. This enables you to use it as an independent gas detection system with two adjustable gas concentration alarms and one fault alarm. Audible alarms, signal lights or similar devices can thus be controlled locally without an additional cable between the transmitter and central controller.

The Polytron 5100 features a Class I, Div. 1 rated explosion-proof enclosure made of aluminum or stainless steel, making it suitable for a wide range of environmental conditions. A protection type e version includes a convenient docking station enabling installation in hazardous atmospheres without running conduit (where approved) and this also facilitates pre-assembly.

The remote sensor connection housing allows you to install the sensor separately from the transmitter. This allows you to simply place the sensor closer to the gas cloud in hard-to-reach locations. The display remains visible at eye level. Since the sensor is connected via an intrinsically safe connection, no conduit cabling is required. The connection also allows 'hot replacement' of the sensor in the hazardous area.
