Abstract

A multiple sensor inclination measuring system includes a plurality of single and dual axis inclination sensors, each sensor including a bridge circuit for generating a signal or pair of signals, each signal having a voltage which is proportional to the degree of inclination of the sensor, and an analog-to-digital converter to convert the signal to a digital word having a binary value representative of the tilt of the sensor. Each sensor is connected to a support unit which includes a microprocessor, memory, and data communication capabilities. Each support unit may include a look-up table which calibrates the unit specifically to the sensor used. The support units all communicate with a main processing unit which synchronizes the digital conversions of the electrical signals and which has the capability of averaging the angle readings of selected sensors over various lengths of time, determining the difference between angle readings of selected sensors, comparing the rates of inclination of selected sensors, and displaying angle readings, average readings, difference readings, and rates of inclination. The main unit may be connected to a printer for printing hard copies of the angle readings as a function of time.
