MEMS Tiltmeter- Installation Procedure & How does it work?

The Encardio-rite Model EAN-90M MEMS Tiltmeter is used in the monitoring of inclination and vertical rotation in structures such as buildings, dams, etc.
Robust and robust during construction, the high-resolution tiltmeter has great temperature stability. It is equipped to have a voltage output which can be detected by any readout unit that can measure the differential voltage output.

Principle of operation

The Model EAN-90M Tiltmeter has a stainless steel housing which has the accurate accelerometer and proper signal conditioning circuit mounted inside it.

The accelerometer picks up the force due to gravity which is at the highest when the accelerometer is rotated to the tilt position of 90-degree and lowest(zero) when the angle of tilt is zero. For all the other tilt angle, the accelerometer force can be determined by the product of the sine of tilt angle and acceleration due to gravity.

The tilt sensor thus provides a bipolar DC voltage output proportional to the sine of tilt angle measured by the tiltmeter. The output is measured as zero when it is placed in an accurately vertical position.

Even though the sensor gives a moderately low-cost tilt measurement, it provides excellent resolution, long term stability and low thermal sensitivity. With the use of suitable mounting accessories which include brackets and anchors, the MEMS tiltmeter can be secured on any vertical surface, horizontal floor, or ceiling.

The difference that has to be understood here is that the Model EAN 90-M is not designed for the complete determination of tilt in structures. It is used to measure the change in the tilt of a structure to which the sensor is attached.

To calculate the change in the tilt of structure, the initial tilt reading when the instrument has been placed on the structure is recorded and subtracted from the …[Continue Reading]
