Diaphragm pressure switches and pressure transmitters are used in many different application areas for monitoring overpressure, vacuum or differential pressure. Their modular design allows custom-made and cost-effective solutions. If necessary, individual product adaptation is also possible. The main area of use for the compact pressure switches series 901 is in monitoring filling levels and filters, as well as in monitoring overpressure, vacuum or differential pressure in closed systems.
These pressure switches are suitable for both liquid and gaseous media including aggressive media. 901 pressure switches with permanent factory setting.
The switching pressure can be defined at a value of between 5 mbar and 12 bar in the overpressure range and between -5 mbar and -900 mbar in the vacuum range.
901 Prescal® pressure switches with scaled adjustment knob Various versions with overlapping adjustment ranges are available. These cover the overpressure range of 5 mbar to 12 bar, as well as the vacuum range of -5 mbar to -700 mbar.
