Barksdale B2T-H12 Pressure Actuated Switch

Engineered by Barksdale, the B2T-H12 is a housed bourdon-tube pressure switch designed for precise control in demanding industrial systems. It covers a 50–1200 psi (3.45–82.8 bar) pressure range and uses a robust bourdon-tube element inside a sealed housing with tamper-proof external adjustment, delivering stable switching points across temperature fluctuations. The pressure port is a 1/4" NPT female connection on standard ranges. Electrical ratings provide switching resilience: up to 10 A at 125/250 VAC and up to 3 A at 480 VAC, with snap-action switching for fast response. The B2T family is noted for high accuracy and rugged construction, including a repeatability of ±1.0% of range at constant temperature. The compact, ready-to-wire design supports panel-mount installations or control-box integrations, and its sturdy housing helps withstand industrial environments while preserving measurement integrity. Typical applications include pressure-based control in hydraulic and pneumatic systems, compressors, pumps, and process equipment where reliable, repeatable setpoints are required. The B2T-H12’s combination of enclosed form factor, external adjustment, and dependable electrical performance makes it a focused solution for customers needing a robust, accurate pressure switch in the 50–1200 psi range.
