Abstract: A force-balance transmitter for producing a pressure signal proportional to the enthalpy of air has a flapper associated with a nozzle and employs a control force acting on the flapper in opposition to a feedback force applied to the flapper by the controlled fluid pressure acting over the area of the nozzle, the control force being produced by the combination of forces exerted on the flapper by two resilient beams subjected to individual bending moments responsive to sensed temperature and sensed humidity respectively.

Abstract: A transducer comprising an electrical conductor located in the field of a permanent magnet or an electromagnet, whereby, by passing a current through the conductor, force will be caused to act between the conductor and the magnet, the transducer including a further electrical conductor connected in a circuit with the first-mentioned conductor so as to carry a current related to the current through the first-mentioned conductor and such as to tend to nullify the effect of that current to alter the field of the magnet linking the first-mentioned conductor. A transducer element is also claimed.

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.

Abstract: A force-measuring apparatus, particularly a weighing cell, has a stationary part 10, a load receiver 60, a measuring transducer 138, and a lever 100 for transmitting a force from the load receiver to the measuring transducer. An improved arrangement is proposed for changing the lever ratio by providing at least two different locations so that the fulcrum pivot flexures can be attached either at positions 112/212 and 118/318 or, alternatively, at positions 114/214 and 116/316 of the lever/stationary part.

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).
