Description
Technical field
The utility model relates to a kind of sensor, especially relates to a kind of pressure displacement integrated transducer.
Background technology
Flood-control wall is the important defence line of guaranteeing the rivers people across the Straits security of the lives and property.On flood-control wall, generally all be provided with passage gate and the moistureproof flap valve that is used for water outlet.The bank elevation all is lower than the water level of setting up defences at the bottom of present most passage gate, therefore, if closing gate is untimely, water inlet will occurs, leak, and influences flood control safety.Equally, if the cast iron flap valve that rivers water delivering orifice along the line is provided with can form tidewater and pour in down a chimney can not be closed fully, does not also bring into play the function of retaining tide.Therefore, normal for guaranteeing riverine flood control facility operation, the keying state of monitoring channel gate and moistureproof flap valve and to close tightness degree most important.
The present way that addresses this problem is to use displacement transducer, and at some in particular cases, in order to obtain more reliable monitoring result, also need know the acting force of flap valve, also needs a force transducer for this reason.Traditional displacement and force transducer are based on electric class and measure sensing technology, as resistance strain gage, string wire meter etc., owing to their poor durability, can't satisfy the long term monitoring of structure.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of gaging pressure simultaneously of high-durability and the pressure displacement integrated transducer of displacement.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of pressure displacement integrated transducer, it comprises a cylinder body, an end is set with pressure rings in the described cylinder body, the afterbody of described pressure rings is provided with Waterproof Pigtail Cable, the outside surface of described pressure rings is pasted and is provided with at least one fiber grating, the other end in the described cylinder body is provided with piston rod, be provided with spring assembly between described pressure rings and the described piston rod, be provided with first packoff between described pressure rings and the described cylinder body, be provided with second packoff between described piston rod and the described cylinder body.
