Electric Contact Pressure Gauge is a type of pressure gauge that uses an electric contact to indicate and measure pressure. It works by measuring the displacement of a diaphragm when subjected to pressure. The displacement is then converted into an electrical signal that is used to switch on or off a contact.
The electric contact pressure gauge is mainly used in applications where two pressure values need to be compared, and the contact needs to be triggered at a particular pressure value. It is commonly used in hydraulics, pneumatic, and other industrial applications where pressure measurement and control are crucial.
There are three types of electric contact pressure gauges:
1. High-Low Switch: In this type of gauge, two contacts are used that triggers when the pressure value is either higher or lower than the set value.
2. High/ Low (Hysteresis) Switch: In this type of gauge, dual-contact is used that triggers when the set value is crossed, and then again when the pressure returns to the original value.
3. Differential Switch: In this type of gauge, two pressure inputs are connected to one or two contacts, and the difference between the two pressures determines the contact action.
In conclusion, the electric contact pressure gauge is a valuable instrument in any process control system that demands providing a signal for pressure measurement and control.
