Measurment Principle
The clinometer is constituted of two single-axis MEMS sensors (Micro-Electro-Mechanical-System) .The sensitivity, reliability and robustness of the sensor, make this instrument a great low cost aid for systems which are monitoring deformation of structures and also rotation and tilt variations.
Installation is simple and immediate, fixed to the wall with the aid of 3 Fischer fixings and a simple initial check with an optical level
Adjustment and refinement plates are available for special applications.
Usually, systems with multiple sensors are produced, the sensors being either separate from each other or interconnected by extension bars to allow the formation of chains for monitoring subsidence and structural deformation.
Instrument chains allow the monitoring of an entire profile (rather than single points) and also provide greater overall accuracy of measurement.
These sensors, with RS485 (MODBUS) exit, allow easy interfacing with our Data Logger CUM3000 and with various other reading and acquisition systems currently available on the national and international market both these ones with analogical and digital output.
