Pressure Gauges
Pressure gauges are measuring instruments for measuring pressure of gases or liquids. Bourdon tube pressure gauges, which use change in Bourdon tube curvature, are generally used, but micromanometer is used for levels of pressure that cannot be measured. There are various types, including general-purpose ones that measure the pressure of general fluids such as oil and compact ones that can be used in narrow spaces, so a product is used according to the fluid to be measured and usage environment. Glycerin pressure gauges inject glycerin into internal mechanisms to enable accurate measurement even in environments with strong vibration, and sealed types are suitable for use outdoors and environments with much dust and moisture. Digital types display the measurement values digitally, so efficient and accurate measurement and reading are possible.
