DriSteem 405725 Flame Sensor
The DriSteem 405725 Flame Sensor is a critical OEM replacement part designed for precision flame monitoring in gas-fired humidification systems, predominantly the DriSteem GTS and GTS-DI series. As a veteran technician knows, maintaining a reliable DC microamp signal is essential for preventing nuisance burner lockouts. This sensor utilizes flame rectification technology to verify combustion, ensuring the gas valve remains energized only when a stable flame is present. Engineered to withstand the high-temperature environment of the burner assembly, the 405725 features a robust electrode rod and high-grade ceramic insulation to prevent current leakage to the ground. When troubleshooting DriSteem GTS ignition modules, a fouled or oxidized sensor is often the culprit behind a "no flame sensed" error. Replacing a worn sensor with this genuine DriSteem humidifier part restores the fast response time needed for safe, efficient steam production and prevents the costly downtime associated with inefficient combustion cycles.
Key Benefits for the Contractor- Ensures flame rectification accuracy to prevent intermittent burner shutdowns and safety lockouts.
- Direct OEM replacement for DriSteem 405725, ensuring fitment and electrical compatibility with GTS humidifier controls.
- Constructed with high-heat resistant materials for long-term durability in industrial gas-fired humidifiers.
- Optimizes combustion efficiency by providing steady feedback to the ignition control board.
- Compact design allows for straightforward installation in tight burner manifold configurations.
How do I test the DriSteem 405725 if I suspect a failure?
Set your multimeter to the DC microamp (µA) scale and wire it in series with the flame sensor lead. You should typically see a reading between 1.0 and 10.0 µA once the burner ignites. If the signal is weak or non-existent despite a clean rod, the sensor or lead wire may be compromised.
Can I clean this sensor instead of replacing it?
While light oxidation can be briefly removed with a non-conductive abrasive pad (like Scotch-Brite), the ceramic insulator can develop hairline cracks that cause electrical tracking to the ground. For critical industrial applications, replacing the sensor is the standard practice to ensure system reliability.
Is this sensor compatible with the GTS-DI (Deionized Water) models?
Yes, the DriSteem 405725 is the standard flame sensing component for the burner section of both the GTS and GTS-DI gas-to-steam units, as they share the same combustion system architecture.
