Product Detailed Description

The Barksdale B1T-A12SS is a high-accuracy, housed Bourdon tube mechanical pressure switch designed for precise pressure control in demanding industrial environments. It features a robust, tamper-proof design with an integrated terminal strip for easy wiring and external adjustment for setpoints. Built with a 316 stainless steel Bourdon tube and pressure connection, it ensures durability and corrosion resistance. This model is part of the B1T series, offering instrument-class accuracy (±1% of full range) and is suitable for rapid cycling at high pressures. While the base B1T series provides NEMA 13 oil- and dust-tight protection, the “A” variant (as in A12SS) indicates an explosion-proof configuration with NEMA 4, 7, and 9 ratings, making it ideal for hazardous locations. It includes a single SPDT (Single Pole Double Throw) contact for reliable switching and built-in over-travel stops to handle pressure surges effectively.

Product Parameters/Specifications

Product Advantages

• Superior Accuracy and Reliability: Instrument-class precision (±1%) ensures consistent performance in critical applications, outperforming many diaphragm or piston-based switches.
• Extended Durability: Built-in over-travel stops and robust 316 SS construction allow for higher proof pressures (up to 24,000 psi) and longer life cycles (millions of operations), ideal for high-cycling environments.
• Hazardous Location Safety: Explosion-proof NEMA 7/9 enclosure prevents ignition in volatile atmospheres, with full compliance for Class I/II hazardous areas.
• User-Friendly Design: Tamper-proof external adjustment simplifies field calibration without disassembly, while the integrated terminal strip facilitates quick wiring.
• Versatile and Rugged: Oil-, dust-, and watertight protection (NEMA 4/13) combined with corrosion-resistant materials supports use in harsh, corrosive conditions like marine or chemical processing.
• Cost-Effective Longevity: Low maintenance needs and resistance to surges reduce downtime and replacement costs compared to less robust alternatives.

Precautions/Notes

• Installation: Ensure the setpoint is adjusted within the upper 65% of the range for maximum accuracy or the lower 65% for optimal longevity; the middle 30% offers the best balance. Avoid exceeding proof pressure to prevent damage.
• Maintenance: Inspect for electrical shorting, leakage, or mechanical wear every 1 million cycles or 6 months. Replace O-rings annually or every 2 million cycles. Field repairs on UL/CSA-listed units may void certifications—consult Barksdale for authorized service.
• Operation: Not suitable for pulsating pressures without dampeners; use in ambient temperatures within -40°F to +185°F. Verify compatibility with media to avoid corrosion of wetted parts.
• Safety: In hazardous locations, follow NEC guidelines for grounding and conduit sealing. Do not use in applications exceeding electrical ratings to prevent arcing or failure.
• Storage: Store in a dry, temperature-controlled environment to preserve seals and accuracy.

Product Applications

The B1T-A12SS is engineered for high-stakes industrial settings requiring precise, reliable pressure monitoring and control in potentially explosive environments. Key applications include:

• Oil & Gas: Pipeline monitoring, compressor controls, and drilling rigs for safe pressure regulation in flammable atmospheres.
• Chemical Processing: Reactor vessels, pumps, and distillation systems to maintain safe operating pressures.
• Hydraulic Systems: Power units, presses, and machine tools in manufacturing for surge protection and automation.
• Marine & Offshore: Shipboard hydraulics, ballast systems, and engine controls in corrosive, hazardous marine conditions.
• Power Generation: Turbine controls, boilers, and fuel systems in energy plants.
• Mining & Metals: Compactors, crushers, and extraction equipment for rugged, high-pressure operations.
• Water/Wastewater: Pump stations and filtration systems in industrial treatment facilities.
