Teledyne Gas & Flame Detection’s MultiTox DGi-TT7-E is an intelligent gas detector utilising a range of different types of sensor. This detector has been designed to make operation and maintenance simple.
The DGi -TT7-E is made from a common housing and electronics with the detection capabilities being determined which sensor, or cartridge is used. A comprehensive assortment of cells are available which are intrinsically safe protected and can be replaced while the detector is in operation, thus minimising system down time. These intelligent, microprocessor driven units are fully configurable when using a wireless hand-held terminal (TLU) or use of the hard wired HART option which offers total flexibility for installation as well as lower service costs. Relay operation and alarm levels are all set through the TLU which is 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. Due to the hot swat field cabling technology, sensors can be swapped in a hazardous area without the need for area declassification. The detector features optional HART Protocol 7th edition output thus enabling full configuration and diagnostics over non-proprietary interface.
