The Dräger PEX 1000 establishes the link between the Polytron SE Ex sensing heads and a control unit. These sensing heads are installed in a hazardous area, which is then monitored for hydrocarbon concentrations. Their measured data is transmitted as mV signals to the PEX 1000, which is placed outside the hazardous zone. Here, the measured data is converted into standardized mA signals and transferred to the control unit (e.g. Dräger REGARD 2410). If limits are exceeded, the control unit activates suitable countermeasures such as ventilation.

A three-core cable connects the PEX 1000 with the control unit and the Polytron SE Ex. The cable length covers a wide range of up to 500 meters. The PEX 1000 can also easily be integrated or upgraded into existing installations and gas warning systems.

The PEX 1000 is very user-friendly and easy to handle. Maintenance and calibration are adjusted directly on the device with just two buttons and two-digit digital display.

While the secondary explosion protection reduces the risks, the primary explosion protection actively prevents the formation of explosive atmospheres. Together with the Polytron SE Ex and a control unit like the Dräger REGARD 2410, the PEX 1000 fulfils all conditions for primary explosion protection and is tested to EN 60 079-29-1.
