Pressure gauges do more than display pipeline pressure in an industrial system. Depending on their output signals, they can also support continuous pressure regulation or trigger equipment to start and stop at preset pressure limits. Remote transmission pressure gauges and electric-contact pressure gauges serve these two different purposes, although their similar appearance can make them easy to confuse.
The key to choosing between them lies in how they transmit pressure information and interact with control equipment. This article compares their structures, working principles, wiring, and control applications to help identify the right type for different pressure-control requirements.
