Barksdale B2T-M32 Pressure Actuated Switch

The Barksdale B2T-M32SS is a stainless-steel Bourdon-tube pressure switch in the B2T family, designed to provide reliable, mechanical actuation when a process pressure reaches a preset level. It uses a 1/4" NPT female process connection and is offered in housed configurations typical of B2T models, including dual-setpoint options. The device delivers a repeatability of ±1.0% at a constant temperature, reflecting instrument-class accuracy within the Bourdon-tube family. The SS suffix denotes stainless steel construction, enhancing durability in demanding environments, while the M32 designation aligns with the 32-range class used by this variant. In practice, it serves to trigger electrical signals or control equipment in hydraulic and pneumatic systems once the set pressure is reached, providing a simple, rugged interface for safety interlocks, alarms, or automated controls.
