Siemens Building Technology AQF3150 Replacement Element
As a veteran HVACR technician, you know that maintaining precise environmental control hinges on the accuracy of your sensors. The Siemens Building Technology AQF3150 Replacement Element is the essential service part for restoring peak performance to your QFA31XX and QFM31XX series humidity and temperature sensors. Specifically engineered for 2 percent duct and outdoor air relative humidity sensing, this exchangeable measuring tip eliminates the need for full sensor replacement when the sensing element drifts or becomes contaminated in demanding industrial or commercial environments.
The AQF3150 utilizes a high-accuracy polymer humidity sensing element designed for rapid response times across the full 0–100% RH range. When integrated with Siemens Q-Series sensors, it ensures stable, reliable feedback for BAS and HVAC control loops. Installation in the field is straightforward, allowing for quick calibration restoration without extensive downtime. This genuine Siemens replacement element maintains the integrity of your IP65-rated enclosures and ensures your climate control systems operate within tight technical tolerances.
Key Benefits- Compatible with QFA31xx and QFM31xx series duct and outdoor air sensors.
- Restores 2% relative humidity accuracy for critical environment monitoring.
- Rapid response sensing technology reduces lag in humidity control loops.
- Field-replaceable measuring tip lowers long-term maintenance costs and minimizes downtime.
- Ensures continuous, precise RH & T sensing in light-industrial and commercial air handling units.
Is the AQF3150 compatible with all Siemens Q-Series sensors?
This specific element is designed for the QFA31XX (room/outdoor) and QFM31XX (duct) series that require 2% accuracy. Always verify your base model number before installation.
Can I install this element myself in the field?
Yes, it is designed as an exchangeable measuring tip for rapid field service. Ensure the power is off and avoid direct impact on the sensing element during the swap to maintain calibration.
Does this part include the immersion housing?
No, the AQF3150 is the internal sensing element/tip only. It is intended to be inserted into your existing Siemens sensor housing.
