Description
BASO Gas Products K16BA-36 Thermocouple Overview
The BASO Gas Products K16BA-36 is a reliable thermocouple engineered for use in standing pilot ignition systems. With a 36-inch lead length and an open circuit output range of 25–35 mV, this thermocouple provides the consistent voltage signal required to keep pilot safety valves open and heating systems operating safely and efficiently.
Key Features
- Open circuit output range: 25–35 mV
- Lead length: 36 inches
- Designed for standing pilot ignition systems
- Generates millivoltage from pilot flame heat to hold safety valve open
- Reliable flame-sensing performance for residential and commercial heating equipment
- Direct replacement for compatible Johnson Controls applications
How It Works
A thermocouple operates on the Seebeck effect — when the tip of the thermocouple is heated by the standing pilot flame, it generates a small millivoltage (25–35 mV open circuit) that signals the gas valve to remain open. If the pilot flame is extinguished, the voltage drops, causing the safety valve to close and shut off gas flow, preventing dangerous gas buildup.
Application
- Standing pilot ignition systems on furnaces, boilers, and water heaters
- Residential and light commercial heating appliances
- Direct replacement for worn or failed thermocouples in compatible equipment
