Product Introduction

----------------------------------------------------------------------

We manufacture phased array probes of various shapes and sizes for different detection applications. Here are schematic diagrams illustrating several types of probes

The frequency range of a typical array probe is 1 MHz to 17 MHz, and the number of chips ranges from 10 to 128. Olympus offers a variety of probes utilizing piezoelectric composite material technology for a wide range of inspections. This section describes Olympus' standard phased array probe. These probes are divided into three types: angle beam probes, integrated wedge probes, and immersion probes.

Other types of probes are specially designed probes according to application needs.

Linear array probe is the most commonly used phased array probe in industrial applications. An important factor in defining phased array probes is the activation aperture of the probe.

Weld series probe

The weld detection probe comes with a casing and a cable extending from the front or top to avoid interference with the scanner probe holder. These probes are suitable for manual and automatic inspection of welds. The new A31 and A32 weld series phased array probes and wedges not only simplify and standardize weld detection by using fewer design solutions, but also improve signal-to-noise ratio.

DMA (Dual Matrix) probe

The dual matrix (DMA) probe consists of two matrix probes connected to the same connector, and has the ability to detect using transmit receive longitudinal wave (TRL) sound beams. These probes have frequencies of 2.0 MHz and 4.0 MHz, and are particularly useful for detecting straight pipes or high attenuation materials with weld deposits.

Double crystal linear array probe

The new dual crystal linear array probe provides various advantages over conventional ultrasonic dual crystal probes for corrosion detection applications. This phased array solution improves productivity through features such as larger beam coverage, faster scanning speed, and C-scan imaging with higher data point density.

Immersion Probes

The design purpose of the immersion probe is to be used in conjunction with a water wedge, or to be used in a immersion chamber when the tested workpiece is partially or completely immersed in water. This type of probe belongs to longitudinal wave probes, but after setting, Rexolite wedges can be used for refracted transverse wave detection.

---

Curved Array Probes

The curved array probe is wrapped in a stainless steel anti-corrosion steel shell, which has waterproof performance within 1 meter below the water surface. The acoustic impedance of this type of probe matches that of water. They can be used in conjunction with all adjustable water immersed wedges, and can not only perform delamination testing on composite materials, but also test the rounded corners of carbon fiber reinforced polymer materials (CFRP).

---

Deep penetration probe

The deep penetration probe can be used in conjunction with various wedges for detecting sound beams at various angles. These probes are specifically designed for deep penetration applications, such as detecting thicker plates, welds, forgings, and materials with multiple noises or grain shapes.

---

Small footprint probe

The small footprint probe can enter narrow areas of the activity space (the footprint size of the A00 probe is 8 × 8 millimeters).

---

Integrated wedge block and probe that meets specifications

This assembly places the integrated wedge and compliant probe in the same housing, giving the probe and wedge assembly a very thin side that can be used for contact angle beam detection. Due to the absence of coupling agents between the probe and wedge contact surface, the coupling state between the probe and wedge will always remain perfect. These probes can be used for manual detection of stress corrosion cracks and can also be used for applications that comply with AWS and DGS specifications. In addition, these probes can also be used for manual weld seam detection on thicker surfaces ranging from 6.35mm to 19mm (butt joints, corner joints, T-joints) at an angle of 40 ° to 70 ° simultaneously.

Wedge block for angle beam probe

The wedge block used for angle beam probes has models that can generate standard refractive angles of 0 °, 45 °, 55 °, and 60 ° in steel, and can perform transverse or longitudinal wave angle beam detection from 30 ° to 70 °. These wedges have stainless steel screw holes that allow them to be securely installed on the probe. Ordered IHC wedges can improve inspection quality: irrigation, installation holes on the wedge frame can be used to connect Olympus scanners, and hard alloy strips can improve wear resistance.

---

Universal (versatile) probe

The combination of various probes and wedges with a wide range of applications has an extremely thin side surface, making it easier to enter areas with limited space. These probes can be used with various wedges for various angle beam detection applications. These probes are not only used for manual or automatic inspection of thicker welds ranging from 6.35mm to 38mm, but also for detecting cracks and weld defects in cast iron, forgings, pipes, fittings, machined parts, and structural components.

---

Near wall probe

The two ends of the near wall probe have short blind spots (the distance from the center of the first chip and the center of the last chip to the edge of the probe housing closest to them is 1.5 millimeters). They can be excellently applied for channel detection of composite materials and for C-scan detection of composite materials (delamination, delamination, and porosity).

Water immersed angular wedge block for curved array probes

The water immersed angular wedge used for curved array probes has a special radius and angle, and its radius can be adjusted to be suitable for various tested workpieces. These wedges are designed for manual scanning and are used in conjunction with a pocket wheel encoder.
