Sensor Technology Ltd. was founded in 1983 near Toronto, Canada.  The company began as a research-driven manufacturer of acoustic transducers, hydrophones and piezoelectric materials.  It has conducted experiments on the space shuttle, the Mir space station, in both the Arctic and the Antarctic and in ocean depths exceeding 20,000 feet.  Over its 30 years in business the company has shifted its focus to industrial applications. 
Sensor Technology Ltd.’s history of R&D lends itself to the company’s strong design capabilities. With in-house machining, assembly and testing facilities, Sensor Technology Ltd. is capable of taking customers through the entire design process from concept, to prototyping, to full-scale production. 

The Tech
Sensor Technology Ltd. manufactures components for sonar arrays and other acoustic systems.
•    Sensor Technology Ltd. manufactures a wide array of piezoelectric ceramic materials.  The company produces hard and soft PZT (Navy Types I, II, III, V, VI), lead titanate, a series of lead metaniobate materials and the unique, ultra-hard PZT, BM200.  In-house CNC machining capabilities allow it to produce a wide range of geometries, from small 0.070” (1.78mm) diameter tubes to plates almost 7” (177.8mm) long.  Uncompromising quality controls ensure consistent piezoelectric ceramic performance, from shipment to shipment.
•    Sensor Technology Ltd. uses its own piezoelectric ceramics to design and manufacture custom acoustic transducers and hydrophones.  Volumes range from one-offs and prototypes to high volume production feeding thousands of pieces each week directly into customer production lines.  Past projects include transducers with multiple transmit frequencies, vector hydrophones, high channel count arrays with side lobe suppression, towed array hydrophones for seismic applications and ruggedized units, capable of withstanding pressures exceeding 10,000 psi or temperatures up to 280° C.
•    Sensor Technology Ltd. designs and manufactures preamps and transformers for piezoelectric acoustic transducers.  These components provide the first layer of electronics, simplifying the process of integrating the sensors into sonar arrays and other acoustic systems.
