TTDM-128
Leak Detection Module
The
TTDM-128
is the primary user alarm panel and system control unit for networked Tracetek systems. TTDM-128 module directly monitors up to 1500 m (5000 ft) 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 of the sensors, the TTDM-128 sounds an alarm, closes relay contacts, turns on a front panel LED and displays the circuit identification and location of the leak on the alphanumeric display. The leak detection event is logged to a non-volatile event history file. All status and event information are made available via the front panel keyboard or RS232/RS485 Modbus digital communication to a host computer, PLC or plant/building automation system.
FEATURES
- Multiple event tracking capability for up to 128 independent sensor circuits.
- Summary relay contacts, LED status lights, LCD information display at the TTDM-128 panel.
- Standard external interface modes include: dry contacts, and RS232/RS485 modbus communication. A 4-20 mA analog output option is available.
- Event history accessible from the front panel or via serial port to identify type of event, time, location, and other parameters for all sensor events or user adjustments and interventions.
- Layered password protection for setup changes.
- Adjustable sensitivity and selectable measurement units.
- Universal power supply for 110/220 Vac 50/60 Hz (24-volt option available).
- Non-volatile memory for event history, setup and network configuration.
- Complete remote operation and monitoring through modbus communications or using optional TT-SUPERVISOR Windows software.

TT5001
TraceTek TT5001 sensing cable detects liquid organic solvents anywhere along its length, but does not react to the presence of water.
TT-MINI-PROBE
The TT-MINI-PROBE can also be used to detect leaks in drip trays or sumps, or low spots where TraceTek sensing cables are inappropriate.
TT3000
Used to detect spills and leaks of aqueous chemicals which includes waste water, acids, bases, hazardous waste streams, etc.
TTFFS
TTFFS-100 detects liquid hydrocarbon fuels such as naphtha, refined products and heavy crude.
