DG-TX7 Intelligent Flammable Gas Detector
Brand: Detcon IncThe MultiXplo DG-TX7 intelligent catalytic based flammable gas detector is used to detect a wide range of gases, including hydrogen (H2).
The device has been designed for ease of installation, operation and maintenance in testing environments.
The DG-TX7 employs a pair of OXYCOL catalytic sensors in a compensated circuitry in order to provide reliable flammable gas detection in harsh environments, as long as oxygen is present.
The intelligent, microprocessor driven unit is fully configurable using a wireless handheld terminal (TLU) or optionally via HART giving true flexibility to the installer.
Parameters such as relay operation and alarm levels are all set via the TLU, hazardous area approved handheld unit.
In addition, the sensor element is protected by the onboard electronics to prevent exposure to over-range LEL gas concentrations. This helps reduce ongoing maintenance and service costs.
The user can select between 4-20 and 0-22 mA depending on system requirements.
The unit may be interfaced directly with a wide range of panels, controllers and PLC’s etc.
Device status, including measured gas level is indicated on a color coded 4 digit LED display.
