BENCHMARK to set the sensitivity of ultrasonic devices

摘要

The invention relates to the field of expertise of industrial safety chemical, petroleum, petrochemical, oil, oil, gas, gas production, gas processing, metallurgical, mining, mining industries, boiler inspection objects and lifting equipment, refrigeration, cryogenic equipment, tanks, pipeline network objects enterprises for storage and processing of grain, railway facilities, facilities engineering and others. known standard (about sample is) to adjust the ultrasonic devices GOST 14782-86 p.1.4.2. Etalon is formed as a unit on a working surface which is the converter unit within an aperture (reflector). This standard allows you to configure only one depth control. Known standard (standard sample enterprise GOST 14782-86 p.2.9.2 chert.5.) Consisting of controlled metal block on the working surface of which is the converter, and at the side - the hole with a flat bottom (reflector). The disadvantage of this standard is the lack of customization options for multiple depth control, which leads to a significant limitation of the instrument settings. Objective: To increase versatility sensitivity adjustment devices, expanding the functionality of the standard, increase the volume control when you set up with a single standard. The stated object is achieved in that the reference sensitivity setup ultrasonic devices, consists of a block at the top of which is a working surface for the transducer and a reflector arranged within the block. What is new is that the reflectors are made of several pieces (for the setting of different inspection depths) and are located on both sides of the reference. The reflectors are in the form of flat-bottomed holes, or as a lateral cylindrical holes or in the form of other types of reflectors, normative documentation provided, depending on the accuracy requirements settings manufacturability, forms the controlled object, or as a combination of all of these reflectors.
