 New Product: TTDM–128 1/30/04
|
The TTDM–128 unit monitors up to 5000 feet (1500 m) of sensor cable and a network of up to 128 remote TraceTek modules. The remote modules may be a combination of sensor interface modules
(TTSIM), relay modules (TT–NRM) or additional TTDM–128 modules. With its networking capability the TTDM–128 provides tremendous flexibility. In terms of system layout options and monitoring capability.
When liquid is detected on any segment of sensor cable, the TTDM–128 sounds and alarm, closes relay contacts, turns on an LED and displays the channel number and location of the leak on an LCD display.
The leak detection event is logged to an event history file and all status and event information is made available via RS232/RS485 MODBUS to any host PLC or plant or building automation system. Each
sensor circuit detects, locates and tracks leaks entirely independent from any other circuits connected to the TTDM–128. There is no loss of sensitivity and no re–mapping required after an initial leak
is detected. A simple map showing where the sensor cable has been installed is the only field calibration requirement.
