Encardio Rite Model EAN-41M is a MEMS tilt sensor (beam sensor) designed for monitoring the inclination and vertical rotation of structures. Any change in a structure that is caused due to construction activity like excavation; tunneling or de-watering that may affect the ground supporting the structure is called a tilt change.
It may also be due to the loading of the structure, such as the loading of a dam during impoundment, the loading of a diaphragm wall during excavation, or the loading of a bridge deck due to wind and traffic. The Data collected from the tiltmeter provide an early warning of possible threatening deformations, giving sufficient time to take corrective measures or evacuation of the area, if necessary.
Tilt Sensor Application
If you’re wondering where tilt sensors are used, they are used in the following monitoring activities:
Operating Principle – How does a tilt sensor work?
The tilt sensor working principle is built around the Micro-electromechanical system (MEMS). Encardio Rite Model EAN-41M beam sensor has a range of ±15°, along with high sensitivity and tilt sensor accuracy mounted inside an aluminum enclosure (beam). It provides a bipolar DC voltage output proportional to the sine of the tilt angle measured by the tiltmeter. The output is zero volts for a truly vertical position.
The MEMS tilt sensor gives a comparatively low-cost tilt measurement solution and yet offers excellent resolution and long-term stability. With the help of mounting accessories like brackets and anchors, the tiltmeter can be secured on any vertical surface, horizontal floor, or ceiling.

Model EAN-41M Tilt Sensor is not designed to measure the absolute determination of the tilt of structures. It measures the change in the tilt of a structure to which it is fixed. Once the instrument is mounted on the structure, the initial tilt reading is noted. Subtracting the initial tilt reading from subsequent tilt readings gives the change in the tilt of the structure over a period of time.
How to install tilt sensors?
Encardio Rite Model EAN-41M can be installed on horizontal as well as vertical surfaces. Let’s start with the installation of horizontal structures.
Tools and accessories required for installation
Installation of Horizontal Tilt Sensor
Installing the anchors
Horizontal sensors are designed to discover the relative vertical displacement of the two anchors at their ends. The distance between the two anchors is known as the gauge length of the tilt sensor. They are usually available in standard gauge lengths of 1, 2, or 3 m, but varied specified lengths are also available.
The sensors are generally used in a string with two tilt sensors sharing a common anchor for fixing.

Fixing the beams
Each sensor is equipped with two mounting angles on each side. The beams can be fixed to the anchors directly using these mounting angles.
However, in case the strings of beams are subject to any torsional movement, use the separately available beam mounting kits as it provides more flexibility.
The figure below shows the correct position of each component of the kit while mounting the beams.
The figure below shows how to mount the EAN-41M horizontal tilt sensor on the wall using the standard mounting kit.
The figure below showcases how to mount the EAN-41M horizontal tilt sensor on the floor using the standard mounting kit.
Installation of Vertical Tilt Sensors
Vertical tilt sensors find their application to determine the relative horizontal displacement of the two anchors at their ends. Similar to the horizontal tilt sensor, the vertical sensors are generally supplied in standard gauge lengths of 1, 2, or 3 m, but other customer-specified lengths are also available.
These sensors are commonly used in a string with two sensors sharing a common anchor for fixing. Vertical tilt sensors consist of a standard EAN-41M tiltmeter, an aluminum beam, 38 mm x 38 mm square and specified gauge length, and mounting hardware for mounting the tiltmeter on the beam, generally packed separately for shipment.
The procedure for fixing the beams is the same as the one described for horizontal surfaces.
