Presssure gauges

Gear-less Pressure Gauge (Spiral Type) SP

- A pressure gauge that does not use gears for the enlarging mechanism and improves durability
- The spiral type winds the Bourdon tube a number of times to set the pointer and directs the pressure.
- Spiral type has marvelous durability because of no sliding part, therefore ultra miniaturization can be realized.
- It is used for pulsating pressure measurement of a Plunger type pump and a portable cylinder for aircraft.
