General Description
Sensor comes with 10 feet of water rope. Additional 10 ft sections are available and can be connected up to 100 feet.
• 10 ft lead and 10 ft water detection rope
• Immediately detects water anywhere along rope
• Expandable up to 100 ft of detection rope
Principle of Operation
The ALTA Wireless Water Rope Sensor detects conductive liquids anywhere along the length of the detection rope by using two wires covered with conducting polymer. When water or conductive liquid contacts the rope, the sensor will immediately turn on the RF radio and transmit the data to the wireless gateway and iMonnit Online Sensor Monitoring and Notification System, allowing the user to immediately receive an alert by SMS text, email or voice call. The sensor rope dries quickly allowing the sensor to reset for next use. Detection rope can be expanded up to 100 feet by simply clicking additional 10 foot sections of detection rope together. Additional sections of water detection rope are available on the Monnit website.
