ICP DAS has unveiled a new liquid leak detection module iSN-104 which features 4 channels for connecting sensors and support for the Modbus RTU industrial protocol, which allows you to organize a liquid leakage detection and alarm system at industrial and domestic facilities, warehouses, pipelines and tanks. When a leak or cable break is detected on the iSN-104 module, the indicator lights up, the audible alarm signal turns on and the state of the Modbus RTU registers changes.
The iSN-104 module is an evolution of the iSN-101 single-channel model. iSN-104 can connect sensor cable or water level sensor.
Leak detection cable
Water-sensing cable сan detect a leak over a large area.
The iSN-104 can be connected to a cable with a break detection function and can be extended up to 500 meters, or a fixed length cable without a break detection function. Connection options are shown in the table:
| Functions | Connecting cable | Leak sensor cable | Terminal resistor |
|---|---|---|---|
| No cable break detection. Can't be extended. |
 CA-LLD-EC-L030 – 3 m |
 CA-LLD-DC100-L010 – 1 m CA-LLD-DC100-L030 – 3 m CA-LLD-DC100-L100 – 10 m CA-LLD-DC100-L300 – 30 m CA-LLD-DC100-L500 – 50 m |
No |
| There is a definition of a cable break. Can be extended up to 500 meters. |
 CA-LLD-DC100X-L010 – 1 m CA-LLD-DC100X-L030 – 3 m CA-LLD-DC100X-L100 – 10 m CA-LLD-DC100X-L300 – 30 m CA-LLD-DC100X-L500 – 50 m |
 CA-LLD-DC100X-TR |
Broken wire detection function is available for modules with the latest firmware.
Water level sensor
Water level sensor with stainless steel contacts allows you to determine the moment the liquid reaches the required level and respond to this event in time.
