Title: Strain gage
Inventor: SATOU YOSHIMI
IPC: G01B7/16
Filed: 1983-04-13
Abstract: PURPOSE:To facilitate the measurement of temperature in a wide range, by attaching thin metal to a gage base made of an insulating brittle material, breaking the metal foil together with the gage base at a value exceeding the limit strain, and measuring the amount of change in electric resistance. CONSTITUTION:A ceramic material is used as an insulating brittle material, which is broken at a value exceeding the limit strain for a gage base 2. A thin metal 3 made of a conductor of nickel chromium alloy or the like is attached to the ceramic gage base 2. When strain is applied to a strain gage and the strain exceeding a limit is yielded, the ceramic gage base 2 is broken. Since the strain is concentrated at the broken part of the gage base, the metal foil 3 is broken at the corresponding part of the strain concentration. Owing to the breakdown of the metal foil 3, the amount of change in electric resistance between gage terminals 6 moves to the state, at which the amount is increased to infinity in a step state, from the state, at which the amount is increased in proportion to the magnitude of the applied strain.

     CONSTITUTION: When a PTO shaft 16 for a high speed rotation is connected to a PTO drive shaft 5, another PTO shaft 18 for a low speed rotation is contained in a container case 19 and hence a sensor 23 is in its operative position. Accordingly, only when a PTO change lever 7 is operated to a high speed position in which a high speed gear 11 is coupled to a hub 23 through a coupling 14, a sensor 25 operates so that pressure oil of a pump is fed to a cylinder 26 to thereby engage a PTO clutch 4. Meanwhile, if the PTO shafts 16, 18 are in their respective opposite positions, the sensor 23 does not operate. Accordingly, the sensor 25 does not operate only when the lever 7 is operated to a low speed position in which a low speed gear 12 is coupled to the hub 13 through the coupling 14, and hence the clutch 4 is engaged by the pressure oil of the pump.
