BASO K15DA-30H Thermocouple

The BASO K15DA-30H Thermocouple is a professional-grade sensing component engineered for high-reliability in standing pilot ignition systems. This heavy-duty thermocouple serves as the direct replacement for K15DS-30 and K15DS-1830H models, ensuring seamless integration into existing thermoelectric gas valves. Built with a 30-inch lead length, it provides the necessary reach for complex furnace and boiler burner assemblies. The unit produces a robust open circuit voltage range of 20 to 28 mV, maintaining a stable signal for the pilot burner safety circuit. With a maximum hot junction temperature rating of 1500°F (816°C), this HVAC thermocouple is designed to withstand the thermal stresses of continuous operation in residential and commercial heating equipment. The 11/32-32 male nut connector ensures a secure, leak-free mechanical connection to the safety shut-off valve, vital for long-term system integrity.

• Universal Compatibility: Specifically designed to replace antiquated Johnson Controls K15DS series units without modification.
• High Thermal Tolerance: Operates efficiently in high-heat environments with a hot junction limit of up to 1500°F.
• Reliable Signal Output: Delivers a consistent 20-28 mV millivolt signal to prevent nuisance pilot outages and service calls.
• Industrial Construction: Features a durable brass and copper build with a stainless steel sheath for superior corrosion resistance in the flame path.

Is the K15DA-30H compatible with non-BASO valves?
Yes, while optimized for BASO, Basoid, and Basotrol valves, the standard 11/32-32 threading allows for interchangeability with many other manufacturers' standing pilot systems.

What is the minimum voltage required for the valve to stay open?
In a typical closed circuit application, the valve usually requires a minimum of 8 mV to hold the internal solenoid, though this thermocouple provides a higher 20-28 mV open circuit output for a reliable safety margin.

Can this thermocouple be used in catalytic heaters?
While primarily used for pilot flames, the K15DA series is rated for a wide temperature range; however, ensure the millivolt output meets your specific appliance's requirements for catalytic ignition.
