Abstract: A zero-strain soil pressure sensor includes a shell provided with a hydraulic oil cavity and a cavity located below the hydraulic oil cavity, a processor, an outer elastic film arranged at the upper end of the hydraulic oil cavity, an inner elastic film arranged between the hydraulic oil cavity and the cavity, an outer strain bridge circuit connected with the outer elastic film, an inner strain bridge circuit connected with the inner elastic film, a piston communicated with the hydraulic oil cavity, and a driving mechanism connected with the piston. The outer strain bridge circuit, the inner strain bridge circuit and the driving mechanism are electrically connected with the processor. The invention has the beneficial effect that the piston is driven by the driving mechanism to control the oil pressure in the hydraulic oil cavity, external soil pressure is balanced through the oil pressure to keep the outer elastic film in an non-deforming state all the time, and only the inner elastic film is deformed, so that the soil arch effect and soil displacement are avoided, and thus the liquid pressure measured by the inner elastic film is the soil pressure, and the measurement result is more accurate.

A gas differential between the gas pressure on said opposing faces is established, and the axial force acting on said shaft is determined as a product of a constant and the pressure differential between the gas pressures on the two faces. Means are provided for supply of gas under overpressure to said body and pressure measuring means are provided for measurement of the pressure differential between the pressures on the two faces of the radially projecting portion. The protruding portion may also constitute a measuring plate which, provided in various manners, is subjected to forces.

Abstract: A tunneling sensor is disclosed having a pair of force rebalance capacitors that are used in a push-pull relationship so as to provide a rebalance force that is a linear function of applied rebalance voltages, which leads to an output voltage that is linearly related to input acceleration. The tunneling sensor comprises a plate electrode that is formed from and attached to a silicon substrate by a pair of torsional flexures, which provide an axis of rotation for the plate electrode. A pendulous mass is formed on a first end of the plate electrode, and a tunnel-effect contact is formed on a second end of the plate electrode. A pair of torque rebalance bridge electrodes are formed on the substrate so as to span the plate electrode. A tunnel-effect tip is formed on the substrate so as to be proximate the tunnel-effect contact and in line with the rotational path that the tunnel-effect contact takes when the plate electrode is rotated.

Abstract: A piezoelectric sensor system according to the invention employs a piezoelectric actuator relay (20) having a piezoelectric element displaceable in response to an actuation voltage and contacts (23, 24) which open or close in accordance with the displacement of the element, wherein the actuator relay (20) is adapted to receive a force (L) to be measured against the displacement. This piezoelectric actuator relay (20) is supplied, by a driver circuit (60), with a varying voltage as the actuation voltage. The relation between the forces (L) and the activation voltages necessary for opening or closing the contacts (23, 24) has been stored in a memory (70). A processor (50) obtains a value of the force (L) based on a value of the actuation voltage at the instant of the opening or closure of the contacts (23, 24) and the relation stored in the memory (70).
