Contact transducers are single-element, longitudinal wave transducers designed for direct contact with an inspection piece.

Contact probes are available in multiple forms ranging from standard, fingertip for difficult-to-access areas to magnetic hold down for stationary positioning on ferrous materials. Inspection technicians use contact transducers in various applications to include straight beam flaw detection and thickness measurements, spotting and sizing delamination, and inspecting plates, billets, bars, and other metallic and nonmetallic components.

Blatek houses its line of standard contact probes in rugged stainless-steel cases with active element diameters that range in size from 0.25” to 1.0”. Blatek’s standard contact probes combine an alumina oxide wear plate with a piezo composite optimized for maximum sensitivity and broad bandwidth. Blatek’s piezo composite elements are known to provide the best signal-to-noise ratio in the industry. Blatek’s standard contact probe frequencies are 1MHz, 2.25MHz, 3.5MHz, 5MHz, and 10MHz. Standard contact probes are available with BNC or UHF connectors. Other connector configurations, frequencies, and custom form factors are available upon request.

An immersion probe is a longitudinal wave transducer with a quarter wavelength layer acoustically matched to water.

Test technicians can use a Rexolite wedge to set up for refracted shear wave inspections. Test technicians use immersion transducers with a water wedge or in an immersion tank where they can partially or fully immerse a test piece in water. Water immersion provides a uniform, fast coupling to quickly scan parts.

Blatek offers the most efficient piezo-composite immersion transducers available. Blatek engineers acoustically match immersion transducers to water for maximum sensitivity, broad bandwidth, and a low signal-to-noise ratio. Blatek immersion transducers are available in a variety of styles to include side looking, paintbrush, extra-miniature, i-R, and phased array. Blatek can provide spherically focused, cylindrically focused, or unfocused immersion transducers. Blatek typically houses immersion probes in durable stainless-steel cases. Blatek offers immersion probes with a wide range of connectors and can provide connection design options for high noise environments.

Oil companies and municipal water and sewage authorities use down-well probes to evaluate the integrity of the cement bond between casing and formation in a completed line.

The transducer is both a transmitter and receiver. The probe generates an image of the borehole wall by transmitting ultrasound pulses and measuring the amplitude and travel time of the reflected signals through the borehole fluid to and from the borehole wall.

Blatek designs down-well probes to meet customers’ exacting performance requirements for elevated temperature, high pressure, and highly abrasive/toxic environments. Blatek scientists acoustically match down-well transducers to the borehole fluid for maximum sensitivity, broad bandwidth, and a low signal-to-noise ratio. Blatek engineers carefully select enclosure materials for durability and operation in elevated temperature, high pressure, highly abrasive/toxic down-well environments.

Time-of-flight diffraction (TOFD) transducers and wedges generate refracted longitudinal waves in steel.

Inspectors routinely use TOFD probes to size cracks. Quality TOFD transducers are highly damped to provide excellent resolution in challenging applications. Premium TOFD transducers use a sensitive piezo composite element.

Blatek has designed piezo composite elements that exhibit a tight, short ringdown and are ideal for the toughest time of flight diffraction measurements. Blatek’s circular TOFD probe frequencies range from 0.5MHz to 10MHz with disc sizes from 0.25" to 1.0". Square and rectangular elements are also available in the same frequency range.

Single and dual element transducers are excellent choices for examining near-surface defects, weld inspection, thickness measurements, and the tough task of inspecting coarse-grained materials.

Competent fabricators of single and dual element transducers can adjust designs for frequency, internal roof angle, element size/shape, and delay path to produce the perfect transducer for any given application.

Blatek develops single and dual element transducers in housings with extremely low mechanical and electrical crosstalk. Blatek engineers match piezo composite elements for maximum sensitivity and select delay materials for high wearability and impedance match to the material under test. Blatek transducers offer multiple advantages to include improved near-surface resolution, good coupling to rough surfaces, and reduced back-scattering noise in coarse-grained or scattering materials. Inspection technicians often use Blatek probes in applications such as measuring remaining wall thickness, corrosion/erosion monitoring, weld overlay inspection, and cladding bond/dis-bond inspection.

Blatek offers an extensive line of Phased Arrays composed of our proprietary piezo composite and paired with single or double matching layer(s).

Blatek divides its Phased Arrays into three categories – angle beam, integrated wedge, and immersion. Blatek scientists design Phased Arrays for maximum sensitivity, broad bandwidth (50%+), and low signal-to-noise ratio. Blatek scientists regularly design phased array probes with unique frequencies, pitches, and elevations to meet customers’ overall size limitations. Blatek engineers follow mutually agreed upon design requirements to place the acoustic stacks in rugged stainless-steel cases with customer-specified cables and connectors.
