PKP Products - Pressure

Pressure Gauges

The PKP pressure gauges include the Bourdon tube, capsule, diaphragm, differential pressure gauge and digital pressure gauge principles. A wide range of measuring ranges, housing sizes, process connections and vibration damping expand the range of measuring instruments. Contacts, double scales, dial markings and externally adjustable pointers are available as options.

Pressure Switches, Sensors and Digital Measuring Devices

Electronic pressure switches are used to measure the pressure of liquids and gases. They can be used in a wide range of operating conditions, from the negative pressure range up to 1000 bar. Both relative and absolute pressure are detected and output as switching points or analog signals. A display serves as an important visual control of the process status and the switching state.
