DGI-TT7 Electrochemical Gas Detector
Manufacturer: Teledyne| DetconThe MultiTox DGI-TT7-E gas detectors employ a wide array of sensor types.
The device has been designed for ease of operation and maintenance.
The DGI-TT7-E 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, including hydrogen sulfide, ammonia and carbon monoxide to name a few. The cells are intrinsically safe protected, and may be replace with the detector powered.
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.
The unit may be interfaced directly with a wide range of panels, controllers and PLC’s etc.
The device offers HART Protocol 7th edition output as an option.
