The HD series of microelectronic overpressure strain gauges are designed for the proportional conversion of pressure into an electrical signal. New solutions in pressure measurement - Silicon on Sapphire technology. Sensitive element of strain gauges is a two-layer sapphire-titanium membrane with monocrystalline silicon strain gauges. Monocrystalline sapphire membrane is an ideal elastic element and in combination with titanium it acquires the leading quality in terms of deformation level, retains elastic properties up to +400°?. Monocrystalline silicon strain gauges are connected to sapphire at the atomic level (heteroepitaxy method) and work practically without hysteresis and fatigue phenomena in time. Unique insulating properties and radiation resistance of sapphire allow to operate the sensitive element in the temperature range from -200 to +350°C, at high electromagnetic interference and radiation exposure. Strain-sensitive elements made of...
