Gas detector DG Series

oxygentoxic gaselectrochemical

Applications •Refineries •Offshore drilling and production platforms •Processing and storage plants •Chemical plants. The MultiTox DG7 Series is a group of intelligent gas detectors employs a wide choice of sensor types. The DGI -TT7-E is used for Toxic gases or Oxygen monitoring. The DG-TT7-S is a solid-state metal oxide semiconductor. The DG-TX7 employs a pair of OXYCOL catalytic sensors All DGi-TT7 are constructed from a common housing and electronics with the detection properties being determined by the type of sensor (cartridge) used. A wide range of cells are available, these cells are intrisically safe protected, and may be replaced with the detector powered which minimises the system down time. The intelligent, microprocessor driven unit is fully configurable using a wireless hand-held terminal (TLU) or by using the hard wired HART option giving true flexibility to the installer and reduced service costs. Elements such as relay operation and alarm levels are all set via the TLU, a hazardous area approved hand-held unit. The unit may be interfaced directly with a wide range of panels, controllers and PLC’s etc. Its integral daylight readable alphanumeric display indicates local status and alarm level. The device has been designed for ease of operation and maintenance.
