Engineered with a high-sensitivity sensor element and extended-range calibration, this sensor monitors NOx from 0-10,000 ppm, making it ideal for large generators, marine auxiliary engines, and industrial boilers. The rugged cast iron housing and dual-heater design ensure reliability in constant-load and cyclic operation.
Extended Range & Resolution
Wide Measurement Span: 0-10,000 ppm NOx with 1 ppm resolution, supporting both low-emission (≤50 ppm) and high-load (≥5,000 ppm) applications.
High-Sensitivity Mode: Automatically switches to low-range calibration for precise control of lean NOx traps (LNTs) in gas engines.
Stationary Engine Optimization
Constant-Load Stability: Maintains accuracy within ±1.5% over 20,000 hours of continuous operation, critical for prime power generators.
Vibration-Isolated Design: Rubber-mounted sensor element reduces stress from engine oscillations in reciprocating machinery.
Heavy-Duty Construction
Cast Iron Housing: Withstands corrosive exhaust gases (SOx, Cl⁻) in biomass and waste-to-energy applications, outlasting standard sensors by 30% in harsh environments.
Dual-Heater Redundancy: Primary and secondary heaters ensure operation even if one fails, with automatic failover for 24/7 reliability.
Industrial-Grade Integration
Modbus RTU Compatibility: Supports industrial communication protocols for integration with SCADA systems, enabling remote monitoring and data logging.
Calibration Flexibility: User-configurable zero/span points via PC software, adapting to unique engine configurations and fuel types.
Power Generation:
Natural gas generators (1-10 MW): Ensures compliance with EPA New Source Performance Standards (NSPS) for NOx ≤ 0.15 g/bhp-hr.
Diesel standby generators (500-2,000 kVA): Provides real-time NOx data for demand-controlled ventilation systems in data centers.
Industrial Processes:
Boilers and furnaces: Monitors NOx in combustion processes for cement plants and refineries, supporting ISO 14001 and EU BREF compliance.
Marine Auxiliaries:
Cruise ship generators (2,000-5,000 kVA): Meets IMO Tier III in port operations, with salt-resistant coatings for marine environments.
Q: Can it measure NOx in biogas-fired engines?
A: Yes, calibrated for biogas (methane-rich) fuels, with automatic correction for high humidity and siloxane contamination.
Q: What is the sensor’s response time in constant-load operation?
A: Maintains <100ms response to slow NOx changes, ideal for steady-state engine control in cogeneration systems.
Q: Does it require a separate data acquisition system?
A: No, integrates directly with engine control panels via Modbus or CAN, reducing hardware costs for industrial setups.
Q: How is the cast iron housing protected against corrosion?
A: Internally coated with aluminized steel and externally painted with heat-resistant epoxy, passing 1,500-hour salt spray testing.
