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.
