Introduces an new instrument that can measure stress in the bolt being installed or tightened by ultrasonic longitudinal waves and transverse wave. The instrument is mainly make up of SCM and connects with a computer. The paper deduces the relationship between stress and the ultrasonic transit time ratio of longitudinal waves and transverse wave and temperature through the relationship of ultrasonic velocity, axial stress and elastic constants. It has been taken into account that temperature affects ultrasonic velocity under stress. This method simplifies measurement and calculation process. The microprocessor in the instrument makes use of the digit technology and the ultrasonic wave transit time and attenuation to get rid of disturbance of noises and error coupling of the transducers. The stress and ultrasonic flying time in the bolt are displayed in digit and graphics and the data measured can be queried and reverted to graphics. Operation and data management of the instrument is simple. Experimental results show that the error of stress is less than ±8 MPa when clamping distance is more than 30 mm and stress is less than 250 MPa.
