CUSTOM ACOUSTIC TRANSDUCERS
Sensor Technology Ltd. has been manufacturing custom acoustic transducers for more than 30 years. Our history of research and development allows us to design custom devices for a broad range of applications and industries. We have produced hundreds of acoustic and ultrasonic transducer designs to meet the requirements of companies building systems for:
- sonar
- trawl and purse-seine fishing net monitoring,
- sub-bottom imaging,
- marine seismic exploration,
- hydrographic surveying and bathymetry,
- oil well monitoring,
- ultrasonic flow measurement and more.
TRANSDUCER TYPES
- Low Frequency Transducers
- Free Flooded Ring (FFR) Transducers
- Ultrasonic Transducers
- Directional Acoustic Transducers (Echo Sounders)
- Omnidirectional (Spherical) Acoustic Transducers
CUSTOM HYDROPHONES
Sensor Technology Ltd. manufactures custom hydrophones. In our 30+ years we have shipped more than a million hydrophones to customers around the globe. This experience is what allows us to design and build custom hydrophones to meet almost any need, regardless of your performance requirements, application or operating environment. We have supplied hydrophones to OEMs building systems for:
- trawl and seine monitoring,
- sub-bottom profiling,
- cetacean and environmental research,
- marine seismic exploration,
- hydrographic surveying and bathymetry,
- medical imaging and more.
HYDROPHONE TYPES
- Multi-Channel Hydrophones
- Broadband Hydrophones
- Hydrophones For Cetacean Research
- Hydrophones Without A Preamplifier
- Towed Array & Seismic
- Spherical Hydrophones
PIEZOELECTRIC CERAMICS
If piezoelectric ceramics are a critical component in the systems you design and build, you know the importance of receiving ceramics that give you consistent performance, batch-after-batch. And when your customers expect you to meet your shipping deadlines, you need a supplier that delivers on time.
For more than 30 years Sensor Technology Ltd. has been exporting piezoelectric ceramics to customers in countries around the globe. Whether a 5 piece prototype batch or a 50,000 piece production run, we provide reliable & consistent ceramic parts, shipped on time.
We custom manufacture piezoelectric ceramics in a wide range of sizes, from miniscule 2.0 mm (0.080”) tubes to long 178 mm (7”) bars. We can hold tight tolerances on size, form (flatness, concentricity, parallelism, etc.), resonance frequency, anti-resonance and capacitance.
MATERIAL TYPES
- Soft PZT
- Hard PZT
- Modified Lead Titanate

PREAMPLIFIERS & ELECTRONICS
Hydrophone Preamplifiers
Sensor Technology Ltd. offers an array of high performance hydrophone preamplifiers. Our preamps provide the matching network required for working with the wide ranging, dynamic impedance of piezoelectric devices and feature low noise and low total harmonic distortion. Gain ranges from 0 dB (buffer preamp) to 40 dB or more. Our hydrophone preamplifiers can be modified for your specific application.
We can also provide custom transformers for acoustic / ultrasonic transducers designed specifically for transmitting.
Broadband Acoustic Transmission System (BATS)
The Sensor Technology Ltd. Broadband Acoustic Transmission System (BATS)is a highly configurable, portable system small enough to be transported and deployed by one operator. The BATS drives a broadband Class III barrelstave flextensional transducer with a transmitting frequency range spanning more than 3 octaves (approx. 1.5 kHz – 15 kHz) and a maximum SPL of 204 dB (ref. μPa/V @ 1 m). Complete specifications and configuration options can be found on the BATS page.
