Pressure Switch with Display PE 827
Bamo PE 827 Pressure Switch with Display is a robust instrument, with 2 NPN contact outputs and 1 analogue output 4-20 mA. This pressure switch integrates a sensor with a heavy-duty ceramic diaphragm. Controlled by a microprocessor, it allows the user to easily access the various configuration parameters, such as trigger points and switching functions. Its LED display guarantees perfect readability in all circumstances. It displays the measured value, the parameters, and the status of outputs.
This pressure switch has a reverse polarity protection circuit, and, short-circuit protection. A diagnostic function is available from the keyboard. This function allows complete control of the electronics as well as the measuring cell and takes note of the memorized pressure peaks.
Continuous control on hydraulic, pneumatic applications, in vacuum, cooling process, filter monitoring, in the range of -1 … 0 … 40 bar.
