However, in actual operation, the ultrasonic bolt pretightening force measuring device usually measures the bolt to be measured in the form of an independent probe, which brings the following problems:
when a user holds the temperature probe, the temperature of the human body can be conducted to the temperature probe, so that the temperature probe generates deviation when measuring the temperature of the bolt;
the independent temperature probe needs longer heat conduction time to reach temperature balance due to larger heat capacity, so that the temperature of the bolt to be measured is accurately measured, and the on-site bolt pretightening force measurement often meets the requirement on the effective rate of the bolt to be measured, so that the measured value of the independent temperature probe is deviated when the temperature balance is not reached;
because independent temperature probe and ultrasonic probe components of a whole that can function independently, field operation personnel often can place temperature probe in the non-bolt position because training is not enough or temperature probe line length is not enough, leads to the measured temperature not the bolt temperature, and then brings the measurement deviation.
