Tilt Meter / Beam Sensor

Beam Sensor (Horizontal and Vertical)Model No. TES-AN-41M

Overview

TES-AN-41M Mems tilt beam sensor is attached to the structures for monitoring any di!erential movement and

tilting of structures. It can be mounted both vertically and horizontally. Model TES-AN-41M Mems tilt beam sensor

has long term reliability and low temperature e!ect.

For monitoring de"ection and deformation of retaining walls, sheet piling, etc., the beam sensors are mounted in

vertical strings. The beam sensor can be also be installed in long horizontal strings to measure di!erential settlement

along railway tracks, tunnels. pipelines, embankments, etc. The beam sensor is available with standard 1 m, 2 m, and

3 m beams. Other lengths are also available on requests.

Tilt changes in structures may be caused due to construction activities such as excavation, tunneling and

de-watering, that a!ect the ground that supports the structure. Changes in tilt may also result from loading of a

structure, such as loading of a dam during impoundment, loading of a diaphram wall during excavation or loading

of a bridge deck due to wind and tra#c. Data from model TES-AN-41M Mems tilt beam sensor provides early

warning of threatening deformations, allowing time for corrective action to be taken or if necessary, for safe

evacuation of the area.

Product Description

Model TES-AN-41M Mems tilt beam sensor consists of a basic sensor housed inside a metal beam, which can be 1 m,

2 m, or 3 m long. The sensor output is ± 2.8 V nominal at ± 10°. This output can be carried over long distances without

any signal degradation. The sensor provides a relatively low cost system which o!ers excellent resolution, long term

stability and a low thermal sensitivity. Movement of the structure causes change in tilt of the beam sensor, which

results in change in output of the sensor. Measurements can be made on horizontal or vertical surfaces. Subsequent

sets of readings show how the structure is behaving and will give an indication of permanent deformations as time

progresses.

Features

• Suitable for hostile & severe environment

• Provides reliable and high resolution readings

• Rugged & robust construction

• Easy to install and take readings

• Can be removed and reused

• Readings can be taken by remote datalogger

Applications

• Monitoring vertical rotation, de"ection and defromation of retaining walls

• Monitoring structures for e!ects of tunneling and excavation

• Monitoring di!erential seetlement along railway tracks

• Monitoring stability of structures in landslide areas

• Monitoring tunnels for convergence and other movements

• To evaluate performance of bridges and struts under load

Tilt Meter / Beam Sensor

Beam Sensor (Horizontal and Vertical)

Model TES-AN-41M Mems tilt beam sensor is provided

with special mounting fastners for horizontal and vertical

installations on concrete structures. For monitoring

di!erential settlement along railway tracks, installation

may be required on wooden railway track sleepers. For

such installation, mounting plates are available (at extra

cost). Please refer to the "gure on the right. The wood

mounting fastners can be sourced locally.

Readout/datalogger

Model TES-AN-41M Mems tilt beam sensor can be read by

portable digital read-out unit. The readings can also be

read or logged at a remote location by an automatic data

acquisition system. In the latter case also, the datalogger is

recommended for taking readings while installation and

for troubleshooting until the beam sensor is "nally

connected to DAS.
