Tilt Beam (TB) sensors

Reference products codes: S700, S7BM

Tilt Beam (TB) sensors can be used both in chain to measure a continuous displacement or in stand alone application to measure the tilt-displacement between two point (ends of the beam).

As all Sisgeo’s MEMS tilt sensor, they use the latest MEMS technology that grant great performance and low temperature dependance.

TB are available in both analogue model (4-20 mA output) or digital version (RS485 – Modbus protocol). Digital TB are designed for horizontal chain installation, whereas analogue TB can be installed vertically or inclined.

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.
