Research and development
Innovative possibilities for our advanced sensor technology
Toyoda Machine Works,Ltd., a predecessor of JTEKT Corporation, was the first company in Japan to develop a semiconductor transducer (Bulk type) that made the piezo resistance effect a principle with the Toyota Central Research & Development Laboratories.
After that we pursued precision and stability, and we have been able to quickly develop and deliver diffusion type pressure transducers.
Since then we have supplied a large number of products.
We have accumulated considerable knowledge and technological capabilities since 1966, and it is this combined experience that will enable us to continue producing cutting-edge semiconductor transducers well into the future.
Main features of JTEKT's transducer
1.Compact & Lightweight
Our PYS-3 line features a small pressure-area of 3mm and a weight of only 2g.
2.Superb response
Our bulk type pressure transducers offer extremely high natural frequencies of above 10k-100kHz/min., making them extremely well suited for the task of measuring pressure waves containing high-frequency components.
3.High precision
Our diffusion type pressure transducers feature a non-linearity of ±0.2% F.S. and ± 0.02% F.S. with repeatability, ensuring highly precise measurement.
