TTSIM-2
Leak Detection Module
The
TTSIM-2
sensor interface module monitors up to 150 meters (500 feet) of TraceTek sensing cable. When liquid is detected, the TTSIM-2 unit indicates the leak, displays the location of the leak and switches a relay to provide local voltage-free contact closure. The TTSIM-2 can also communicate to a host monitoring system such as TraceTek TTDM-128 or directly to a PLC or other host system using standard protocols. The low cost of the TTSIM-2 makes it economical to build very robust systems with many small independent sensing cable segments. No field calibration is required
