Pressure Vacuum Sensor

Model  Description 
250 01 900  femto Vacuum-Sensor / Switch, Teach-button, 0 to -1 bar
250 01 898  femto Vacuum pressure sensor - switch, -1 to +1 bar
250 01 899  femto Vacuum pressure-Sensor / Switch, -1 to +10 bar
The calibrated and temperture compensated sensor generates high-precision signals which are
processed by an integrated circuit and transformed to an open collector and an analog output signal.
The switchpoint with the corresponding hysteresis and switching logic can be adjusted by means of the
teach buttons.

The programming with the push buttons can be done with onstanding pressure and a manometer.
The sensor can be ordered with G-thread, NPTthread or flange-adapter.
