Title: Improved force to direct current transducers
Filed: 1956-11-22
Abstract: 811,889. Fluid-pressure servomotor control systems. FIELDEN ELECTRONICS Ltd. Nov. 22, 1956 [Feb. 20, 1956], No. 35722/56. Class 135. [Also in Group XXXVIII] A mechanical force is applied to a pivoted member and the resulting torque is opposed by that due to an electric current passing through a coil attached to the member and linking a constant magnetic field; a fluid pressure is varied by the position of the member and controls the value of a resistance in the circuit through which the current is flowing to maintain the position of the member substantially constant. Application of a force F to the beam 36 causes it to approach the nozzle 44 and thus restrict the issue of fluid supplied via the pipe 46. The resultant back-pressure in the tube causes the diaphragm 54 to rise and compress the carbon pile 14. The current flowing in the coil 78 then increases, causing the hollow cylinder 80 to be attracted towards the magnet 82 and pull down the beam which is attached to the top of 80. The magnitude of the current in the coil gives a measure of the force F and is indicated by suitable means connected to the " LOAD " terminals. The force may be exerted by a spring, bellows, Bourdon tube or diaphragm, to measure e.g. pressure, temperature, fluid flow or mechanical movement exerted against the flexure 38 and counterweights 40, 42 which normally balance the beam. Fluctuations in the pressure of the fluid source are smoothed out by the fluid supply on the voltage to the transformer 16 are compensated by movement of the carbon pile causing the beam 36 to take up a slightly different position.
