Gas detector D-ReX PoS²

infraredelectrochemicalcatalytic

Based on the proven D-ReX platform, the D-ReX PoS² combines compact design, high measurement precision, and maximum service convenience. Specifically developed for the requirements of semiconductor manufacturing, it enables reliable gas monitoring even in areas with very limited space. The integrated pump safely draws in the sample gas at the point of sampling (PoS) – over distances of up to 30 meters from the device, for example from pipelines, gas distribution systems, gas storage areas, scrubbers, or cleanrooms. For maintenance purposes, the device front can be opened without tools, giving quick access to the sensor and pump mechanism. Integration into higher-level systems is achieved via Power over Ethernet (PoE) or via the industry standards 4–20 mA and Modbus (RS-485). - One system for every requirement: The D-ReX PoS² is a space- and cost-saving gas detection device for a wide range of applications. The sample gas is drawn in by the integrated pump, and the smart sensor detects hazardous gas concentrations — both instantaneous and long-term average values. For gases that require a pyrolyzer, the additional Py-ReX module is available. - Smart sensors and easy servicing: Electrochemical, catalytic, infrared, and PID sensors for more than 60 toxic, corrosive, and combustible gases as well as oxygen are available. The sensors are pre-configured, and the sensor cartridges can be replaced quickly and easily after opening the front panel — completely without tools. Only actual wear parts, such as sensors and the pump mechanism, are replaced, while the sensor cassette and pump electronics are reused. This minimizes both maintenance costs and effort. - Flexible installation: Whether mounted on a wall or DIN rail – the D-ReX PoS² adapts to your installation requirements. When replacing the gas detection unit, only two clips need to be released; the connection terminal with wiring and tubing remains in place. The transmitter unit can be exchanged just as quickly and easily as the sensor cartridge. - Clear and precise information: The large TFT color display provides all necessary information on the monitored gas, the measured concentration, the device status, and any faults in plain text – allowing immediate recognition and response. - Modern communication: For state-of-the-art connectivity, the D-ReX PoS² is equipped with a PoE-enabled LAN interface (10/100 Mbit/s) for fast and secure data transmission and the capability to be addressed via network or internet. Alternatively, analog integration into a 4–20 mA infrastructure or digital communication via the proven RS-485 industry standard (Modbus) is also possible. To implement safety actions, the D-ReX PoS² features three internal relays with single-pole changeover contacts for free programming — for example, to trigger external alarms or close valves.
