NOGS Sensors - Reliability of Level in ESP Ash Hoppers
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.
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.
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.
Designed for high-demand industries, including:
ESP Fly Ash Hoppers
Buffer Hoppers
MD Vessels
Nuva Feeders
and more.
The NOGS Sensor redefines hopper-level detection by offering a non-contact, non-hazardous, and continuous measurement solution. It transforms dusty, blind hoppers into transparent, monitorable assets—enhancing safety, efficiency, and operational control.
