Function and purpose

The sensor VT593 Spot Leak Sensor detects water by increasing capacitance on measuring an increase in capacitance between two metal poles . The detector is encapsulated in plastic housing. Due on the spot, all housed within a durable plastic casing. Unlike traditional metal-based sensors, it resists corrosion over time thanks to the low applied voltages and the applied leakage detection principle, it does not rust over time.Can be connected to any analog port (A1...A8) non-corrosive detection method. This design makes it ideal for long-term applications in environments prone to leaks.

The sensor is compatible with any analog port of the Vutlan monitoring unit .The maximum amount and is easy to integrate. Its scalability is enhanced by the VT408/Sensor extension unit, allowing you to increase both the number of sensors and maximum length can be extended using the VT408 / Sensor extension unitthe overall length of the sensor network.

Use cases

1. Data Centers: It can detect water leaks under raised floors on the spot or near critical equipment, preventing costly damage to IT infrastructure.

2. Industrial Facilities: Helps monitor areas prone to leaks, such as around or under machinery, boilers, heaters, or under piping systems.

3. Residential and Commercial Spaces: Used to detect leaks in kitchens, bathrooms, boilers, and near appliances such as washing machines, and boilers.

4. Water Level Meter: The sensor can be used to detect if the water has reached a particular height. For example in a water tray.

This sensor is ideal for long-term monitoring where corrosion could be an issue, and it works seamlessly with Vutlan systems for comprehensive monitoring.

Cable pinouts

1. The sensor uses a standard Vutlan analog sensor cable (RJ11/RJ12 6P4C to RJ11/RJ12 6P4C) for connecting to the monitoring unit. You can find further instructions in the Analog Sensors Connection article

2. The detector uses two wires. It has a black and red wire. Plus or minus is irrelevant.
