Drager PEX 3000 is a fixed gas detector for flammable gas. Suitable for use in explosive gas atmospheres and explosive dust atmospheres (Zones 1, 2, 21, and 22). The detector has two measuring range versions of 0-100%LEL and 0-10%LEL. Both are available in small or medium-size housing. Finally, there is a remote option, transmitter only (no sensor) available with the same two housing versions, meaning six models for the entire PEX 3000 range.
The sensors installed are Drager’s DD type designed for fast response enabled by a mesh inlet design detecting a hazard before a potentially explosive atmosphere is generated. The PEX 3000 models XTR 0010 and XTR 0011 are equipped with a low drift LC sensor, making them suitable for low concentration or leak detection applications.
Power requirement for install is 12 to 30 v DC. The medium housing variants have entries for horizontal or vertical cables. Controller and sensor connect by spring EX approved terminations. You can open the Ex e junction box in a hazardous area to perform maintenance and calibration. Using the two internal push buttons and the internal seven-segment digital display, you can perform many different activities, including one-person calibration. No additional hardware is required, e.g. a handheld terminal.
