Claims

[Scope of utility model registration request]

In a strain gauge type displacement transducer that converts the displacement of a measurement target relative to a reference object into force using a spring, and converts the strain generated in a strain body receiving the force into an electric signal using a strain gauge to detect the displacement, a guide tube having a cylindrical shape; a sealed casing connected to one end of the guide tube, the connected side being sealed by a diaphragm, and the other end being sealed by a sealing means for leading out an input/output guard wire in an airtight state; a displacement transmitting rod whose proximal end side is removably inserted into and removably inserted into the guide tube and moves linearly in the axial direction in response to the movement of the object to be measured; and the guide so as to come into contact with the center of the diaphragm a force transmitting member inserted into a tube; a spring interposed between the displacement transmitting rod in the guide tube or a member substantially integral therewith and the force transmitting member; and a diaphragm in the sealed casing. 1. A strain casing type displacement transducer comprising: a strain casing attached to the diaphragm for converting strain generated in the diaphragm into an electrical signal.
