2017-12-27 IMPEDANCE TRANSDUCERS

The “3T” company has developed the innovative impedance transducer of the combined SP-15 type. The work was carried out in cooperation with “AKA-SCAN” (АКА-СКАН) and “Scientific and Production Center ”KROPUS” (НПЦ КРОПУС) companies. SP-15 transducer is designed to control composite and cellular materials used in various industries, including aircraft construction and shipbuilding. It’s compatible with flaw detectors ID-92, VECTOR, AD-50, AD-60.

SP-15 transducer has an original design, based on a fundamentally new construction of the internal piezoacoustic module and using innovative polymeric materials. Innovative design and engineering solutions provided a noticeable reduction in overall dimensions, high energy efficiency, improved sensitivity to defects and high repeatability. Detailed information about the transducer is placed on the website.

2017-02-17 PRICE 2017

The nomenclature and the prices for production have been updated. The range of transducers has been expanded. This year, type П111 thickness gauge (of high resolution), П111 thickness gauge under foreign standards, П121 SENDAST under foreign standards were added. The nomenclature of prisms for the TOFD method was added. PROFI Y-shaped cables were added. The price policy on transducers П113 TOFD is simplified. Now their price is fixed and does not depend on quantity, as it was earlier.

2017-02-15 MANUFACTURING CUSTOM SPECIAL-PURPOSE TRANSDUCERS

The «3T» company manufactured specialized transducers П311-5.0-6-12.7МКС by the order of “KROPUS” Scientific-production center. These contact-slotted direct sensors with a frequency of 5 MHz, designed to measure the thickness of steel sheets from 2 to 16 mm in the industrial ultrasonic complex.

Transducers are intended for work through a water layer up to 1 mm. They have for 5 MHz useful signals, extremely short on time, lasting not more than 0,43mks at a level of 20 dB, which is guaranteed to give a clear separation of multiple reflections at a minimum sheet thickness of 2 mm. Also transducers have an internal prism with a double delay of 12.7mks that provides two useful echo pulses at a thickness of the sheet 16 of mm inside "a prismatic window". Thus, transducers allow to apply an accurate and stable algorithm for determining thickness of a sheet by two bottom echo signals in all range of steel sheets thickness from 2 to 16 mm.

2017-02-11 DEVELOPMENT OF IMPEDANCE TRANSDUCERS

The "3T" company in cooperation with the companies "AKA-SCAN" (АКА-СКАН ) and "Scientific and Production Center ”KROPUS” (НПЦ КРОПУС ) began developing innovative transducers for the impedance method of nondestructive testing, used in the control of multi-layer composite and honeycomb materials, including aviation ones.

Such joint work is aimed at the creation of fundamentally new designs both combined transducers (СП), and separately-combined sensors (РСП). This will ensure high stability and repeatability of parameters, increase sensitivity to defects and significantly reduce the overall dimensions of transducers.

Fundamentally new construction of piezoacoustic module, and also using innovative polymer materials lie at the base of the new sensor designs.

New impedance transducers will be designed to work with flaw detectors ИД-91М, ИД-92НМ, ВЕКТОР, АД-60К (ID-91M, ID-92NM, VECTOR, AD-60K).

Transducers П111-2,5-12 give broadband useful signals (the duration is less than 1μs at a level of -20 dB) on steel and have an interesting ergonomics that is different from all, adapted for convenient finger retention. The transducers are designed to work with any ultrasonic thickness gauges and general-purpose flaw detectors.

The publication on the site of detailed technical information on transducers П111-2,5-12 is expected in February 2017.

2016-09-09 REDUCTION OF THE ARROW IN SENDAST П121-2.5-65 AND П121-2.5-70.

Upgrade of manufacturing technologies of the P121-2.5-65 SENDAST and П121-2.5-70 SENDAST transducers is carried out. Nominal "arrow" is at П121-2.5-65 SENDAST is reduced from 12,5 mm to 10 mm. At П121-2.5-70 SENDAST it’s reduced from 13,5 mm to 11 mm. At that we succeeded to save the previous low level of own reverberation - noise performance which always tends to a sharp deterioration at small "arrows" of transducers in angle beam transducers.
