Epson Toyocom Develops Quartz Oscillator-based High Precision Pressure Sensors.Tokyo, Japan, Nov 17, 2005 - (JCNN JCNN Japan Corporate News Network ) - Epson Toyocom has commercialized its TSU series of high precision pressure measurement sensors with quartz oscillators, and starts shipment in sample quantities for 400,000 yen ($3,400) per unit from late November. The TSU sensor uses fluctuations in the built-in oscillator's frequency occurring due to pressures applied. The product incorporates a double-ended tuning fork crystal unit, which offers superior stability and quick responsiveness, in order to achieve pressure measurement with high sensitivity as well as superb reliability, hysteresis hysteresis (hĭs'tərē`sĭs), phenomenon in which the response of a physical system to an external influence depends not only on the present magnitude of that influence but also on the previous history of the system. , and temperature characteristics. Equipped also with an oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air circuit for acquiring frequency from the product, the sensor can reduce effects of the cable length, making it easier to be mounted in devices. The sensor will be exhibited along with demonstration systems at the INCHEM INCHEM International Programme on Chemical Safety (WHO) TOKYO 2005 Chemical Plant Engineering Show held at Tokyo Big Sight Tokyo Big Sight (東京ビッグサイト from November 15 through 18.
