Model of tilt sensor system

This paper describes the structural concept of an intelligent sensor system for tilt measurement. The accelerometer principle is used for the measurement. The system enables measurement in both axes of the plane. Measurement is controlled by a microprocessor. Measured data are sent via a bus to a PC. The PC is used for data storage and further calculations. The program controls the performance of defined functions, including calibration, by communication between the sensor system and the PC. It is possible to switch between manual (more precise) and automatic calibration of the position setup of the system. The system has measurement precision of 0.5° for each axis in a ±80° range, with no measurable hysteresis, and an immediate response to tilt change. The sensor system is temperature compensated. The LabView development tool is utilized as a service program.
