About Us

Sensor Technology Ltd. manufactures custom acoustic transducers, hydrophones and piezoelectric ceramic materials. Any of the items listed on this site can be modified to meet your requirements; our expertise is in custom products. Sensor Technology Ltd. has the design capability to turn your specifications into a prototype and the production facility to turn your prototype into a high volume product.

We regularly service a wide number of maritime industries, including fisheries & fish tagging, as well a broad range of other sectors including oil & gas (e.g. land and marine seismic, well logging, wireline tools), leak detection, defense, ultrasonic welding, ultrasonic cleaning & megasonic cleaning, medical imaging and non-destructive testing (NDT). We also provide highly specialized transducers for unique applications involving high temperatures, high pressures and/or other harsh environments.

Sensor Technology Ltd. provides high quality piezoelectric ceramics and acoustic transducers as components for mission critical systems. Quality is paramount.


Sensor Technology Ltd. was founded in 1983 in Collingwood, Ontario, Canada as a subsidiary of Blue Mountain Pottery. For over thirty years we have been manufacturing piezoelectric ceramic materials, acoustic transducers, hydrophones and matching electronics (preamplifiers and transformers) all at one facility.


R&D is a cornerstone of Sensor Technology Ltd. Whether doing esoteric research on the Mir space station, the Antarctic or the deepest sea floor (we’ve been to all of them), or driving industry-focused development to get more out of a product, R&D keeps us advancing. Our decades of practical experience and the knowledge gleaned from research and development provide a foundation for everything we do, from designing a custom transducer to improving our production methods.


Quality is our number one objective.
