A pressure switch, which falls under the category of instrumentation equipment, is used for regulating pressure, controlling, and preventing pressure buildup in pressurized environments in industrial settings.. In other words, this device can easily change the pressure status and prevent damage to various components. A pressure switch consists of two parts: a transducer (sensor) and an electrical switch. In a pressure switch or controller, when the pressure reaches the set value, the contact is activated, sending an electrical signal, and the switch is turned off. Pressure switches can also be designed to disconnect or connect the system in case of excessive or reduced pressure.
Types of Pressure Switches Based on Functionality:
Pneumatic Pressure Switch:
Air Pressure Switch
Hydraulic Pressure Switch:
Water Pressure Switch
Steam Pressure Switch
Gas Pressure Switch
Explosion-Proof Pressure Switch
Applications of Pressure Switches:
- Electronic gas compressors
- Charging control inside batteries
- Traffic counting and gas station pumps
- Pressure panels in sliding doors
- Activating alarms in case of pressure drop in airplanes
- Water pumps
- Switching in high currents, such as in pumps and drives
