Versatile & DurableTechnisonic offers a wide range of immersion probes in various styles for a wide range of needs. Slimline, Large Diameter, Right Angle and Flange are some of the housing styles available, as well as pencil style probes. Each is constructed using high quality stainless steel housing and features surface knurling on most styles for a comfortable, non-slip grip. Optimized for performance and durability.
ISL, IRA, ISL-RA and Pencil Probe styles are available in General Purpose (GP), High Resolution (HR) and Very High Resolution (VHR) models
ILD, IF and ILD-RA styles are available in General Purpose (GP), High Resolution (HR) and Super Punch (SP) models.
Due to the many factors involved in specifying an Immersion Probe they are all built to-order.
Technisonic Research manufactures Immersion probes for virtually all applications, including: through transmission testing of composites to high resolution flaw detection of critical metals and ceramics.
Select: Housing Style, Diameter, Frequency, Crystal/Damping, Focus Type and Distance
General Purpose (GP) Series
Offers the best combination of sensitivity and resolution for the majority of contact flaw detection applications and recommended for the majority of pulse-echo applications. Typically having two to three full ring cycles, these transducers are tuned to provide the best balance between gain and resolution for general purpose testing, with a bandwidth of 30% to 60% at -6 dB.
Super Punch (SP) Series
The Super Punch Series provides maximum gain for penetration of highly attentuative or thick materials. They have little or no damping and a tuning network coupled with piezoelectric crystals designed for very high output. These narrow band transducers have less resolution than the GP Series. Typical bandwidth is 20% to 40% at -6 dB.
High Resolution (HR) Series
Designed for optimum resolution and maximum bandwidth. The HR Series are broadband transducers, making them an excellent choice for thickness gaging applications. While gain is somewhat lower than the GP Series, they are damped to the limits of current technology, exhibiting one or two ring cycles with a bandwidth of 60% to 100% at -6 dB.
Very High Resolution (VHR) Series
For applications requiring detection of small, near-surface defects, the VHR series is recommended. This series offers increased sensitivity while maintaining the high-damped characteristics of the HR Series. Typical bandwidth is 50% to 100% at -6 dB.
Slimline Housing Style (ISL)
The Slimline Housing Style (ISL) is an excellent choice for most immersion testing applications. This style will accommodate element diameters up to 1/2" and features a stainless steel housing for rugged dependability.
Right Angle Housing Style (IRA)
The Right Angle Housing Style (IRA) is an excellent choice when the application requires a sound path at a right angle to the connector, such as thru-transmission testing or testing inside the diameter of bore holes or limited access areas. This style will accommodate element diameters up to 1/2" and features a stainless steel housing for rugged dependability.
The ISL and IRA Housing Styles both feature waterproof UHF connectors and epoxy lenses to optimize performance and durability. Spherical or cylindrical focusing is available, to increase sensitivity to critical flaws or to improve near-surface resolution.
Right Angle Reflector (ISL-RA)
A Right Angle Reflector (ISL-RA) is available for the ISL Transducer, to direct the sound beam 90 degrees into hard to reach areas. Other angles are available on request.
Large Diameter Housing Style (ILD)
The Large Diameter Housing Style (ILD) is the housing of choice for general purpose testing when element diameters greater then 1/2" are desired. The stainless steel housing features a water-proof UHF connector and an acoustically matched epoxy lens to optimize performance and prevent water intrusion.
Flange Housing Style (IF)
The Flange Housing Style (IF) is designed to fit the 1.375" diameter search tube systems found in many immersion and squirter systems. The stainless steel housing and acoustically matched epoxy lens ensures optimum transducer performance and durability.
The ILD and IF housing styles are both available with spherical or cylindrical focusing to increase sensitivity to critical flaws or to improve near surface resolution.
Right Angle Reflector (ILD-RA)
A Right Angle Reflector (ILD-RA) is available for the ILD transducer to direct the sound beam 90 degrees into hard to reach areas. Other angles are available upon request.
Technisonic offers three pencil housing styles (IPM, IPML and IPU) accommodating .250" diameter elements. All feature stainless steel housings and acoustically matched epoxy lenses for optimum transducer performance and durability. The IPM, IPML and IPU are all available with spherical or cylindrical focusing to increase sensitivity to critical flaws or to improve near surface resolution.
IPM and IPML Styles
The IPM Model is 1" long while the IPML is 1.5" long. A microdot connector is standard on both. These are ideal for applications where transducer size constraints are encountered.
IPU Style
The IPU Style features a knurled flange and a UHF connector for easy insertion into standard immersion systems. A right angle mounted element is available on special order
Right Angle Reflector (IP-RA)
A Right Angle Reflector (IP-RA) is available to direct the sound beam 90 degrees into hard to reach areas. Other angles are available.
