D-Tiltmeter – Digital MEMS Tiltmeters

Reference products codes: S541HD, S542HD

D-TILTMETERS are designed for applications that require high accuracy and low thermal drift. The digital tilt meter small dimensions perfetc fit the installation on hystorical structures, churchs, mosques, etc…

The latest MEMS technology and the Sisgeo’s designed electronic parts grant great performaces and reliability. 

For the lower measuring range (±2.5° and ±5°) Sisgeo suggest to use also the adjustable support plate that, thanks to the 3 screws, permits to easily set-up the zero and erase little installation mistakes.

Digital tilt meters may be read locally using New Leonardo portable readout, or centralized with OMNIAlog datalogger for remote monitoring.

Tiltmeters are instruments that measure angles respect to the gravity acceleration vector. To get this result an accelerometer is required. It measures the projection of acceleration gravity on its sensing axis. Sensor can have 1, 2 or even 3 sensing axes.

The MEMS (Micro Electro Mechanical Systems) implementation of accelerometers it’s pretty young (about 20years) but mature enough to have its strong reliability been proven. MEMS are indeed silicon chips machined to create a mechanical part inside. The required electronic to read out the signal is inside the same chip.

The working principle is a spring-mass system: a mass (rotor) is anchored with springs to a fix frame (stator). When an acceleration occurs, the rotor moves respect to the stator loading or unloading the springs. That’s it: the displacement measurement is proportional to the applied acceleration. Displacement is measured with different technologies inside the chip but in its simplest form is related to a capacitance measure.

Sisgeo uses the state-of-the-art of MEMS accelerometers that implement several methods to compensate temperature variation and reduce the cross-axis error reaching very high accuracy.
