Finder 072.11 Floor Level Sensor for Monitoring Relays

The Finder 072.11 is a specialized floor-mounted conductive level sensor engineered for the precise detection of liquid presence. Designed to integrate seamlessly with Finder 72.01 and 72.11 monitoring relays, this device serves as a critical component in safety systems aimed at identifying leaks or flooding at the floor level. Its robust construction ensures reliable performance in detecting conductive liquids, making it an essential tool for maintaining environmental safety in both industrial facilities and residential buildings.

Advantages

The primary advantage of this sensor lies in its high sensitivity to conductive liquids, which allows for rapid detection of unwanted water or chemical spills. By providing a direct interface with compatible monitoring relays, it enables automated responses to potential flood hazards, thereby minimizing the risk of property damage. The floor-mounted design is specifically optimized for low-profile installation, ensuring that it remains unobtrusive while effectively monitoring the immediate floor area for any signs of moisture or liquid accumulation.

Suitable for

• Leak detection in residential basements and utility rooms
• Monitoring for liquid spills in industrial production areas
• Flood prevention systems in server rooms or technical facilities
• Safety monitoring for conductive liquid storage tanks

When it may not be suitable

This sensor is designed exclusively for conductive liquids and will not function with non-conductive substances such as oils, fuels, or certain chemical solvents. Furthermore, it is not intended for use in environments where the floor surface is constantly wet or submerged, as this would trigger a continuous alarm state.

Key specifications

• Type: Conductive floor level sensor
• Compatibility: Finder 72.01 and 72.11 monitoring relays
• Mounting: Floor-mounted
• Detection medium: Conductive liquids

How to use

Installation involves securing the sensor to the floor surface in the area where liquid accumulation is most likely to occur. The sensor must be wired directly to the input terminals of a compatible Finder monitoring relay. Once connected, the relay monitors the electrical resistance across the sensor electrodes. When a conductive liquid bridges the gap between the electrodes, the circuit is closed, triggering the relay to activate a connected alarm or shut-off valve.

What to consider before purchase

• Verify that the liquid to be monitored is electrically conductive
• Ensure compatibility with your existing Finder 72.01 or 72.11 relay system
• Assess the floor surface for proper mounting conditions
• Confirm that the installation area is free from constant moisture that could cause false triggers

Usage recommendations

Regularly inspect the sensor electrodes to ensure they remain clean and free of debris or mineral deposits, as accumulation can interfere with the sensitivity and reliability of the liquid detection process.
