Pressure Switch 901 Prescal® Adjustable

adjustable from -700 mbar to 12 bar

Categories Pressure, Pressure Switches

Engineered for demanding industrial environments, Beck pressure switches safeguard equipment and processes by reliably monitoring overpressure and vacuum across a wide range of media. Our versatile Series 901 covers everything from fine low‑pressure and vacuum control to high‑pressure cut‑out up to 12 bar; choose factory‑set versions for repeatable switching or the Prescal variants with a scaled adjustment knob for quick, tool‑free setpoint tuning—even for aggressive liquids and gases when configured with the right materials.
