Electrolevel Beam Sensor

If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

Electrolevel Beam Sensors detect differential movement and rotation in structures. Two versions of the beam sensor are available: horizontal for monitoring settlement or heave and vertical for monitoring lateral displacement and convergence.

The Electrolevel Beam Sensor measures rotation of structures in the vertical plane.

The sensor is based on the well established Fredericks 0711 series electrolevel sensor. The sensor mounting incorporates an adjustment for zeroing and protects the sensor against thermal gradients.

The Electrolevel Beam sensor consists of a precision glass electrolevel vial mounted in an inert ceramic compound which is itself placed in an adjustable mount. Once installed, thumb-wheels at one end allow the sensor to be adjusted to the zero position using a handheld readout.

The sensor is attached to a rigid beam for installation and various beam lengths are available. Both ends of the beam are fixed using anchor bolts. When multiple beams are placed end to end, a differential displacement profile of the structure from anchor point to anchor point can be derived.

Product Features:

• Multiple beams in a chain give a complete displacement profile
• Simple, well proven device, ideal for measuring tilt in structures
• Accurate and precise
• Measures tilt along the whole length of a beam
• Measures vertical rotation
