Barksdale B2T-A48SS Pressure Actuated Switch 240-4800 PSI

The Barksdale B2T-A48SS is a robust, adjustable pressure actuated switch designed for high-pressure industrial applications. Manufactured by Barksdale Controls Division (now part of Crane Co.), this Bourdon tube-based switch activates or deactivates electrical circuits based on pressure changes, making it ideal for monitoring and controlling systems in hydraulic, pneumatic, and process industries such as oil and gas, manufacturing, and heavy machinery. Key features include a wide adjustable range from 240 to 4800 PSI (16.6 to 331 BAR), with a proof pressure of 7200 PSI (497 BAR), ensuring reliability under extreme conditions. It offers precise setpoint adjustments via a simple turn mechanism (clockwise to increase, counterclockwise to decrease) and supports various electrical ratings for AC and DC voltages, enhancing compatibility with diverse control systems. Advantages over similar products include its durable NEMA 4 enclosure for harsh environments, high accuracy, and long-term stability, reducing maintenance needs. Drawbacks may include its vintage design, potentially lacking modern digital interfaces, and the need for manual calibration. This model excels in applications requiring high-pressure thresholds, providing safety interlocks, alarms, or automated shutdowns, outperforming lower-range switches in demanding scenarios.
