Barksdale B1T-A32SS Bourdon Tube Pressure Switch

The Barksdale B1T-A32SS Bourdon Tube Pressure Switch is a stainless‑steel, housed Bourdon-tube switch with a single setpoint and a 1/4" NPT female pressure connection, designed for precise pressure control in industrial equipment. It features a terminal-strip housing and tamper‑proof external adjustment for stable, repeatable operation, with a published repeatability of ±1.0% at a constant temperature. The unit carries a electrical rating of 10 A at 125/250 VAC and 3 A at 480 VAC, enabling it to switch moderate loads, and it actuates in the 16–39 psi range. Standard pressure ranges offered with this family include 12, 48, 65, 120, and 180 psi, depending on the exact variant. The stainless steel bourdon tube provides corrosion resistance in harsh environments, and the B1T/B2T family supports high‑precision switching across a broad spectrum, with working pressures up to 18,000 psi and proof pressures up to 24,000 psi for housed models.
