Using strain gage, these pressure transducers are sensors that measure pressure as electric signals. Minebea manufactures high-precision pressure transducers that apply Silicon On Sapphire technology; and prolonged stability-type pressure transducers that use strain gages. Connected to various measuring devices for measurement purposes, these devices perform displaying, recording, controlling, monitoring the pressure, etc.
Direct Pressure-Type Sensors with Silicon On Sapphire (SOS) Technology -
The pressure transducers have a silicon thin film (epitaxial growth) formed on a sapphire (Al2O3 single crystal) board. Using this silicon thin film, silicon semiconductor strain gages have their electrical resistance wires themselves connected to a sapphire board, consisting of an ideal sensor that is extremely stabilized physically and electrically.
Features:
- Highly accurate pressure transmitter 0.2%R.O. as a standard by SOS technology.
- including Non-linearity, Hysteresis and Repeatability.) 0.1 %R.O. is also available as a high accurate type.
- High reliability and durability by SOS technology.
- Can correspond to the absolute pressure and compound pressure
- Small size and light weight
- Wide range pressure from 200kPa to 50MPa can be measure.
- Three kinds (Cable directly connected type), (connector type) and (terminal box type)
