BASO K15DA-24 Thermocouple

The BASO K15DA-24 Thermocouple is a professional-grade sensing element engineered for high-reliability performance in standing pilot ignition systems. This 24-inch universal thermocouple serves as the direct replacement for K15DS-24 units, ensuring seamless integration into existing gas valves and burners. Operating within an open circuit mV range of 20 to 28 mV, it provides the precise thermal-to-electric conversion necessary for consistent pilot safety monitoring. Built to withstand the rigorous conditions of commercial and residential heating environments, the BASO K15DA-24 features a heavy-duty copper lead and a specialized tip construction designed for optimal heat transfer and rapid response times. For contractors troubleshooting millivolt systems, this component is the industry standard for stabilizing pilot flame sensor performance and preventing nuisance shutdowns in gas-fired equipment.

Key Benefits

• Broad Compatibility: Functions as a drop-in universal thermocouple replacement for various BASO and OEM standing pilot applications.
• Optimized Signal: Maintains a stable 20-28 mV open circuit output to ensure the solenoid valve remains energized during operation.
• Simplified Installation: The 24-inch lead length provides ample reach for diverse burner configurations and internal cabinet routing.
• Proven Reliability: Engineered specifically for gas furnace pilot components, reducing callback rates and ensuring system uptime.

Common Questions

Is the BASO K15DA-24 compatible with LP gas systems?
Yes, this thermocouple is designed to operate with both Natural Gas and Liquid Propane standing pilot systems, provided the pilot flame is properly adjusted to engulf the top 1/2-inch of the tip.

Can I use the K15DA-24 to replace a K15DS-24?
Yes, the K15DA-24 is the certified direct replacement for the K15DS-24, maintaining the same technical specifications and physical dimensions.

What is the expected millivolt output under load?
While the open circuit range is 20-28 mV, you should typically see 10-14 mV under a normal closed-circuit load when connected to the gas valve magnet operative.
