Pressure Gauge
Explosion-proof Micro Pressure Gauge with Switch Contact ECI
Explosion-proof Micro Pressure Gauge with Switch Contact ECI
The ECI contact pressure gauge uses a Bourdon tube as its measuring element, which can be made of different materials depending on the measured medium. It is suitable for the micropressure measurement of viscous media. By connecting or disconnecting the contacts between the instrument pointer and the set pointer, it controls the switching of circuits in the system to achieve automatic control and alarm functions.
