    Heat-resistant Sputter Gages Achieve Pressure Measurement at High-temperature

    To enable pressure measurement at high temperature, PHC-B series pressure transducers adopt thin-film strain gage formed by sputtering.The sensor part is a flush, diaphragm detecting pressure directly on a flat surface without pressure medium, thus enabling pressure measurement without missing momentary pressure changes. In addition, the flush diaphragm makes these transducers suitable for measuring not only liquid or gas pressure but also pressure of highly viscous medium.The small-sized design and flexible cable make them easy to use even in limited space.
