Drager PEX 3000

The transmitter Drager PEX 3000 is a gas detector for the continuous monitoring of flammable gases and vapours in the ambient air.

The gas concentration, which is detected in a range lower than the Lower Explosive Limit (100 %LEL), is converted to an industry standard 4 to 20 mA signal. Central controllers, like the Drager REGARD are used to evaluate the signal and activate automatic countermeasures and alarm devices.

When opening the enclosure, a two digit 7 segment display with two push buttons is accessible to perform menu guided calibration and maintenance. With the type XTR 0090, a remote version is also available. Other enclosure versions with cable glands on the side are available.

Easy to install

Three leads of the measuring cable (max. length 2.400 m, shielding is recommended) are pushed into the ex-approved spring cage clamps. The electrical connection is extremely reliable.

One man calibration

Maintenance of the Drager PEX 3000 can be performed by opening the transmitter - without declassifying the hazardous area. By means of two push buttons and a two digit 7 segment display, the calibration procedure is menu guided without needing an additional hand-held terminal.

Systems solutions

The sensors are based on the catalytic bead measuring principle and contain poison resistant Drager beads, which have been proven for decades. The small shockresistant enclosure (EEx e) is made of conductive, glass fiber reinforced polyester. Combined with a suitable 4 to 20 mA controller the Drager PEX 3000 transmitters satisfy the customers’ requirements for maximum safety and system availability.

Comprehensive explosion protection

The Drager PEX 3000 is approved according the ATEX directive for a temperature range between - 40 and + 65 °C. The approval is for potentially explosive gas- and dust-atmospheres (zones 1, 2, 21, and 22).

Detection of very low concentrations

The transmitter Drager PEX 3000 type XTR 0010 is equipped with a special low drift sensor for reliable detection of gas concentrations between 0 and 10 %LEL. radiation.
