| 摘要 |
An electronic inclinometer and a centrally controlled network of inclinometers are disclosed. A resistive or capacitive inclinometer sensor measures inclination in two orthogonal axes. Measuring electrodes can be provided on the exterior of a dielectric sensor cell isolated from a sensor fluid. In another embodiment, measuring electrodes comprise pins partially immersed in a cell fluid contained in a metal housing and reference electrodes are provided to compensate for temperature and electrochemical changes in the sensor. Sensor signals are converted to frequency signals that are processed by a microprocessor having a unique logical address and preferably having an external solid state memory. A plurality of inclinometers can be arranged in multiple logical branches to be centrally controlled. The controller operates the network in real time or in a programmable timed autonomous mode. Network data can be presented in a graphical 3D format using software provided on the controller.
