Barksdale B1S-S48SS Bourdon Tube Pressure Switch 6000 Psi

Product Description

The BARKSDALE B1S-S48SS is a Bourdon tube pressure switch designed for industrial and mechanical systems that require reliable, repeatable pressure sensing at high operating pressures. Rated to a maximum pressure setting of 6000 psi, this switch features a 316 stainless steel wetted material construction for corrosion resistance in demanding fluid and gas media. It uses an SPDT contact form with 1% repeatability, making it well suited for control circuits that depend on consistent switching thresholds. The electrical connection is provided via 12-inch free leads, and the unit accepts a 1/4-inch NPTF threaded port for installation into standard pressure taps.

This pressure switch is applicable in industrial process systems, hydraulic circuits, pneumatic controls, and mechanical equipment where high-pressure switching is required. It is appropriate for systems handling fluids or gases compatible with 316 stainless steel wetted components. The wide temperature operating range of -40 to 165 degrees F makes it suitable for both cold-environment and moderate-heat applications. Licensed mechanical or industrial service technicians typically specify and install this type of component in process control, OEM machinery, and heavy equipment pressure-monitoring circuits.

Key Features

• Maximum pressure setting of 6000 psi for high-pressure applications
• 316 stainless steel wetted material for corrosion resistance
• SPDT contact form with 1% repeatability for consistent switching
• 12-inch free leads for flexible electrical connection routing
• Operating temperature range of -40 to 165 degrees F
• Deadband range of 40 to 85 psi for reliable differential switching

Compatibility

Designed as an OEM-style replacement or direct-install Bourdon tube pressure switch for industrial and mechanical systems using 1/4-inch NPTF pressure ports and requiring SPDT switching up to 6000 psi.

Installation Notes

Installation should be performed by a qualified mechanical or instrumentation technician. De-energize all electrical circuits and relieve system pressure completely before removing or installing this switch. The 1/4-inch NPTF threaded connection should be made with appropriate thread sealant compatible with the media in the system. Verify amperage and voltage ratings against the control circuit requirements before wiring the free leads.
