ABSTRACT:
A direct-acting pressure sensor capable in the low-pressure range and including a pressure-sensitive assembly constituted by inner and outer concentrically-arranged curved springs anchored at one end in a socket to define a pressure region therebetween, within which is disposed an elongated, flexible bladder forming an internal pressure chamber communicating with a fluid input socket. The springs are joined at their free end to form a tip whose travel is indicative of the pressure of fluid applied to the sensor. The bladder initially assumes a curved form conforming to the curvature of the springs; but when subjected to internal pressure by an applied fluid, it seeks to straighten out to an extent determined by the level of pressure. The elongated bladder is formed by an elastomeric sleeve incorporating a helical reinforcing coil whereby when subjected to internal pressure, it is free to flex and straighten out, but is prevented by the coil from dilating, thereby maintaining a proportional relationship between the applied pressure and the indication thereof to provide an accurate reading.
