high pressure gauge

...The measurement range of pressure gauges is from the vacuum region up to about 2 GPa. Pressure gauges that measure atmospheric pressure are called barometers, those that measure vacuum pressure below standard atmospheric pressure are called vacuum gauges, and those that measure pressures of several hundred MPa or more are sometimes called high pressure gauges. Also, those that measure the pressure difference between two pressure systems are called differential pressure gauges, and those that measure particularly small pressure differences are called micromanometers or micro-differential pressure gauges. ...

*Some of the terminology that refers to "high pressure gauge" is listed below.

…圧力計の測定範囲は真空領域用から約2GPaまである。圧力計のうちで，大気の圧力を測るものを気圧計，標準大気圧以下の真空圧力を測るものを真空計と呼び，数百MPa以上の圧力を測るものを高圧計high pressure gaugeと呼ぶこともある。また，二つの圧力系の圧力差を測るものを差圧計differential pressure gaugeといい，このうちとくに微小な圧力差を測るものを微圧計または微差圧計という。…
