PSC Electronic Pressure Switch

Brand: KOBOLD Instruments, Inc.

The electronic KOBOLD pressure switch PSC with integrated display is used for continuous pressure monitoring and allows simple switching point programming without pressurization.

For each switching point, the contact function (NC contact/ NO contact), the reset points, the switch types (n/p switch) and the switching function (hysteresis/window function) can be programmed.

Switching currents ranging from a few μA to 500 mA can be switched by the output transistors. The long-term proven ceramic or thin-film cells give this pressure switch very good repeating accuracy and a long life, even at high load alternation.

The rotating display and rotating connection allow the switch also to be used under extreme mounting conditions.

Its high-quality stainless steel housing makes the pressure switch also suitable for unfavourable environmental conditions.

For the higher pressure ranges, all wetted parts are made of stainless steel, making almost all media restrictions unnecessary for the electronic pressure switch. The electronic pressure switch PSC can be used for a wide range of measuring tasks in hydraulics and pneumatics.
