CoverSensor with optical fiber

for building monitoring

The LANCIER CoverSensor has been specially developed for the monitoring of manhole covers and other building openings. Its self-contained design and the materials used have been engineered for use in harsh environments, such as those found in manhole structures. Without external function-determining elements, it is particularly insensitive to manipulation, corrosion and wear.

The CoverSensor (1) is mounted on a slide (2) under spring tension. It is screwed firmly to a manhole wall, for example, so that it touches the manhole cover (3) at a ferromagnetic point. The spring-loaded slide is pretensioned to compensate for tilting movements of the manhole cover. Mounting on doors and other building openings is similar.

A glass fiber (4) acts as a measuring wire and loops through up to four CoverSensors.

Opening the manhole cover changes the fiber's characteristics, thus causing the affected manhole to be detected and reported by the LANCIER Monitoring system.

The alarm is triggered decentrally via relay outputs or via Modbus to a remote control system or via IP network to the LANCIER Monitoring UMS system.

Black box principle

The sensor has no moving external function determining elements and is therefore insensitive to manipulation, corrosion and wear.
