The company began as a research-driven manufacturer of acoustic transducers, hydrophones and piezoelectric materi-als. 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 com- pany 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 ca- pable 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. manufac- tures a wide array of piezoelectric ce-ramic materials. The company produc- es 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 pro- duce a wide range of geometries, from small 0.070? (1.78mm) diameter tubes to plates almost 7? (177.8mm) long. Uncompromising quality controls en-sure consistent piezoelectric ceramic performance, from shipment to ship-ment. Sensor Technology Ltd. uses its own piezoelectric ceramics to design and manufacture custom acoustic trans- ducers and hydrophones. Volumes range from one-offs and prototypes to high volume production feeding thou- sands of pieces each week directly into customer production lines. Past projects include transducers with multiple trans-mit 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 trans- formers for piezoelectric acoustic trans-ducers. These components provide the  rst layer of electronics, simplifying the process of integrating the sensors into sonar arrays and other acoustic Marine Technology Reporter 67MTR #6 (66-81).indd 67MTR #6 (66-81).indd 677/31/2014 10:06:26 AM7/31/2014 10:06:26 AM
