TTK FG-BBOX-LL Satellite Devices


  • FG-NET Satellite Device
  • Monitoring up to 2360m Sense Cables
  • Dynamic Leak Evolution Analysis
  • Location of Faults on Cable
  • Exclusive for Oil Sense Cable

TTK FG-BBOX-LL is a satellite device of the TTK FG-NET Digital Unit. It is designed to be connected with oil leak detection sense cables only, for industry Long Line application. Same function principal as FG-BBOX, the FG-BBOX-LL is monitored by FG-NET via a standard Ethernet network. It expands FG-NET to manage two additional circuits of sense cables with up to 118 (2 x 59) addresses of additional Sense Cables. The FG-BBOX-LL detects multiple simultaneous leak location to the concerned sense cable. All command and control is centralised to the FG-NET, FG-BBOX-LL is not equipped with display so it can be discretely located. FG-BBOX-LL connects to the FG-NET through the facilities Ethernet network, eliminating the need for additional connections. In the event of a fault on the sense cables connected to the FG-BBOX-LL, the relevant relay contact is activated and the LED on the relevant circuit switched to red. On the FG-NET unit, the alarm appears on its touch screen, the responses are identical as a fault on the sense cable physically connected on the FG-NET unit.
