ABSTRACT:
A pressure measuring device is provided with a change-over valve connecting the pressure sensor either with the pressure to be measured or with a reference pressure. The change-over valve is actuated by a separate control pressure and will protect the pressure sensor from the influence of the pressure medium to be measured in the spring-loaded idle position of the valve.
