Pressure Sensor
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.
Pressure sensors
SOS type pressure transmitter
Introduction of SOS type pressure sensor

- 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. Approximately 60 units are used in each H-IIA rocket.
