The Dräger PEX 1000 is a converter module that converts the mV signals of the Dräger Polytron SE Ex DD sensing heads into mA signals and sends them to a control unit like the Dräger REGARD 2410. Together with the Dräger Polytron SE Ex DD, the PEX 1000 fulfils the conditions set down for primary explosion protection.

Benefits

The monitoring team

• The Dräger PEX 1000 establishes the link between the Polytron SE Ex DD 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.

Easy to use

• 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.

Quickly ready for action

• A three-core cable connects the PEX 1000 with the control unit and the Polytron SE Ex DD. 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.

Metrological functionality test

• 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 DD 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.
