Overview
The Barksdale B2S-H32SS-S0441 is a mechanically actuated pressure switch designed for precise pressure monitoring and control in industrial hydraulic and pneumatic systems. This stripped configuration features a Bourdon tube sensing element and dual setpoint control, making it suitable for pump and compressor protection, pressure relief sequencing, and system monitoring applications. The B2S series delivers high accuracy and durability across a wide range of pressure ratings.
Key Features
- Dual setpoint (make and break) adjustment for versatile control logic
- Stripped design allows integration into custom or OEM control panels
- High repeatability and reliability in demanding industrial environments
- Bourdon tube mechanical sensing—no calibration or electronic maintenance required
- 316 stainless steel wetted parts for corrosion resistance
- Proof pressure rating supports transient system spikes
