NOGS Sensor - Naturally Occurring Gamma-ray Sensor
The NOGS Sensor is a state-of-the-art, non-contact continuous level measurement device specifically designed for ESP (Electrostatic Precipitator) fly ash hoppers. Installed externally—without the need for invasive cut-outs or system shutdown—it delivers operator-friendly, reliable, and maintenance-free operation.
How It Works
How It Works
Leverages naturally occurring gamma radiation from trace radionuclides within fly ash.
Employs an onboard processor that filters out ambient noise and isolates the ash-generated gamma signal.
Converts gamma-ray intensity variations into precise continuous level measurements—no radioactive source required.
In contrast to conventional systems, NOGS functions solely as a detector, utilizing the fly ash itself as the gamma emitter.
Key Advantages
Key Advantages
Completely Non-Intrusive & Safe
No drilling, no structural modifications, and no external radioactive sources—ensuring maximum safety and compliance.True Continuous Monitoring
Unlike point-level switches, it offers real-time, continuous readings of hopper fill levels.Minimal Maintenance & Long Lifespan
No consumable parts like radioactive sources, with a lifecycle of up to 10 years and self-diagnostics for temperature, grounding, and analog outputs.Robust in Harsh Environments
Built for extremes: −40 °C to +85 °C, sealed to IP66, and operates on 100–240 VAC or 18–36 VDC.Easy Integration
Offers standard 4–20 mA analog output and features local display or optional remote calibration.
