Barrel Testing System (Part 2)

Systems equipped with modern weapons increasingly require maintenance inspection must take place on a regular basis, to ensure the accuracy and safety during use. For the artillery system, the regular inspection and maintenance of the barrel is always a very important task requiring high precision. To meet this demand, the world now has a number of manufacturers have been developing and testing systems to serve barrel test applications measuring the types of barrel from inside diameter measuring distortion, curvature, applications to measure the parameters of helical grooves, or defects in the barrel.

C. Calibration:

The first calibration is done by the manufacture. All parts of the system contain special features for self-diagnostic. However, the operator should do a periodic calibration once a year or more often if it is required. The system includes special calibration block, which allows checking instrument’s accuracy anytime and fixing calibration table if it is necessary. The calibration takes 10-15 minutes. All calibration processes are automatic.

 

The calibration block contains a caliber (see pictures), which is used to correlate the readings of the system with factory values in order to check the system's accuracy. The inner surface of the caliber emulates a plenty of pipes with different diameters in all working range. In order to calibrate, the probe should be inserted into the calibration block as it is showed on the picture below. The calibration starts automatically after pushing “Calibration” button.
