摘要： Disclosed is a fluid level sensor including a float mounted for movement in a mounting tube by a pair of spiral springs which are relatively rigid in a radial direction but relatively flexible in a longitudinal direction. At the top of the float a magnet is located and at the top of the mounting tube, a Hall effect device is located. As fluid enters the mounting tube through apertures in the lower portion, the float is gradually buoyed and moves closer to the Hall effect device changing its electrical output. Because the springs position the float inside the mounting tube, striction and hysteresis in conventional float supports is eliminated as well as wear between the float and the outer tube. Measurement range may be changed by changing float length and outer tube length as well as the spring constants themselves.

摘要： A two axis sensor is provided for detecting angular movement relative to either of two mutually perpendicular axes. The device includes a two-axis sensor comprising an upwardly directed, spherically shaped common electrode, an upwardly directed spherically shaped insulating member uniformly spaced from the common electrode to form a cavity therebetween, the common electrode and the insulating member being sealed to each other about respective peripheries thereof, with a dielectric fluid contained in the cavity, a plurality of detecting electrodes provided on an underside of the insulating member, the detecting electrodes formed by a selectively applied conductive surface coating on the underside, and means for detecting variations in capacitance proportional to movement of the sensor relative to each of two mutually perpendicular axes by reason of movement of the dielectric fluid within the cavity.
