FAQ

How long does it take from the time the sensor ribbon gets wet to the time of radio transmission?: The time until radio transmission varies depending on the amount of liquid leaked onto the sensor ribbon.
With 3-4 drops of room-temperature tap water, it takes 1 to 3 minutes; if the sensor ribbon is completely submerged, it transmits in about 10 seconds. Also, while it is wet, it continues to transmit wirelessly at intervals similar to the times mentioned above.

Does the length of the sensor ribbon affect the time until radio transmission?: The time until radio transmission does not change based on the length of the sensor ribbon or the position where the liquid is absorbed. Please select the appropriate sensor ribbon length for your site from the product lineup.

Is it possible to detect liquids and leaks other than water?: In addition to water, the sensor can detect electrolyte liquids such as acids, alkalis, and salt water. However, depending on the concentration and type of liquid, detection may not be possible, or the sensor may be damaged (destroyed). We ask that you thoroughly evaluate the sensor before use. Oils and organic solvents cannot be detected due to the operating principle. If you plan to use it for detection other than water, please contact our sales window for consultation.

Is it possible to detect condensation?: Yes, it is possible.
If you do not want to detect condensation, you can use the sensor by employing measures to prevent condensation, such as installing it on the outside of insulation material.

How long is the life of the sensor ribbon/wireless tag? Can they be used repeatedly?: For "Sensor Ribbon I", we generally recommend replacing the sensor ribbon if it leaks and gets wet. "Sensor Ribbon II" can be used repeatedly. Please replace it by using the Alive Status Monitoring Timer (optional) or after approximately 500 hours of cumulative power generation. The "wireless tag" can be used repeatedly.

Can sensor ribbons be cut to the required length?: The sensor ribbon cannot be cut and used. Cutting it can cause the electrodes to short-circuit at the cut section, leading to malfunctions such as failure to detect leaks.

How is the sensor ribbon fixed?: It can be fixed with double-sided tape, cable ties, wiring clips, or similar. Please check the User's Manual for precautions regarding installation.

I would like to borrow a demo unit of the batteryless leak sensor for functional evaluation.: We lend out batteryless leak sensor units after reviewing the details of your project. For more information, please contact our sales window.
