Abstract
The utility model discloses a GBY type tool type strain sensor comprising a body; the strain sensor is characterized in that an elastomer is arranged in the body, and a strain bridge and a machinery transmission device are also arranged in the body; one end of the strain bridge is connected with a signal output end; one end of the machinery transmission device is connected with a watertight device arranged outside the body; two ends of the body are fixed with a mounting clamp. The GBY type tool type strain sensor employs a bearing elastomeric material stress concentration principle, uses the full bridge bridging mode, so the bridge arm coefficient can reach a maximum lever (Kn=4); strict processing art is carried out, processing technique measurements of selecting, pasting, pressing, solidifying, drying and repeat moistureproof sealing of the resistance strain gauge are carried out, so the sensor has very high output sensitivity and long term stabilization performance, and the history that the resistance strain gauge can be only used for one time is changed, thereby saving man power, material resources and time for complexly pasting a large number of resistance strain gauges; the GBY type tool type strain sensor is good in cost performance, so strain test is more economic, safer and efficient.
