摘要： It is aimed to provide a strain detector having a fewer number of mounting parts and high operation efficiency and usability. The strain detector is provided with a cylindrical strain generator to be strained upon receiving a load, a resistor element which is arranged on the outer circumferential surface of the strain generator and whose resistance varies depending on the amount of strain, a signal processing circuit connected with the resistor element and screw portions arranged above and below the strain generator to sandwich the strain generator. The strain generator and the screw portions are integrated.

摘要： A strain sensor improved in detection accuracy without variation of bending stresses applied to the strain detecting element. The sensor substrate has a first fixing hole at one end and a second fixing hole at the other end, a detecting hole at the center, and at least one strain detecting element on the upper surface or lower surfce thereof. The first fixing member is press-fitted into the first fixing hole. The second fixing member is press-fitted into the second fixing hole. The detecting member is press-fitted into the detecting hole. Further, when an external force is applied to the detecting member, strain generated due to the positional shift of the detecting member is detected by the strain detecting element with respect to the first fixing member and the second fixing member.

摘要： A fixing member is composed of an upper washer and a lower washer; and a sensor substrate is sandwiched and held by the upper and lower washers. A strain-detecting element is disposed on the sensor substrate. A strain sensor as configured above is fixed onto a measurement target via the fixing member. Accordingly, the strain sensor does not generate an output signal when no external force is applied, demonstrating stable characteristics.

摘要： A strain detector includes a bridge circuit having at least two strain resistance elements, a substrate, a first fixed member, and a second fixed member. The substrate has a circuit portion electrically connected to the strain resistance elements. The strain resistance elements are arranged on the substrate. The first fixed member is fixed to a center of an area, where an outer periphery of the area is set at a position at which the strain resistance elements are arranged. The second fixed member is fixed outside the position, where the strain resistance elements are arranged at the substrate. A center of an axis of the first fixed member, a center of an axis of the second fixed member, and the center of the area are positioned on a straight line, and the first fixed member and the second fixed member are arranged on two mutually opposed surfaces of the substrate.
