Engineered with a platinum RTD element and Inconel 625 sheath, this sensor withstands continuous operation at 1,050°C and transient peaks up to 1,200°C, making it ideal for turbocharged engines, SCR systems, and gasoline particulate filters (GPFs).
Extreme Temperature Performance
1,050°C Continuous Use: Platinum thin-film sensor element with ±2°C accuracy (at 800°C), exceeding ISO 19453 thermal cycling standards.
Rapid Response: 50ms time constant (T63) for fast feedback to ECU, critical for preventing catalyst overheating in transient engine loads.
Durable Construction
Inconel 625 Sheath: Resists oxidation and thermal fatigue in high-temperature exhaust, with a 10,000-hour service life in harsh environments.
Vibration Resistance: Passes 50g random vibration testing (MIL-STD-810G), ensuring reliability in off-road and marine applications.
Precision Measurement
Wide Temperature Range: -40°C to 1,050°C (withstands 1,200°C for 10-minute peaks), supporting both low-load idling and full-power operation.
EMC Compliance: Shielded cable reduces interference from engine electronics, meeting CISPR 25 Class 5 radiated emissions standards.
Installation Versatility
Universal Thread Size: M12x1.25 or M14x1.5 options fit most exhaust systems, with optional 90° and 180° bend configurations for tight spaces.
OEM-Level Calibration: Pre-calibrated to NIST-traceable standards, ensuring seamless integration with Bosch, Cummins, and Delphi ECUs.
Heavy-Duty Diesel Engines:
Truck SCR systems: Monitors catalyst inlet temperature to prevent ammonia slip and thermal degradation.
Construction machinery: Protects turbochargers and GPFs from overheating during high-load operations.
Gasoline Engines:
Direct-injection turbo engines: Provides temperature data for GPF regeneration, ensuring efficient particulate matter (PM) reduction.
Marine Engines:
Main propulsion systems: Prevents exhaust manifold overheating in high-speed marine vessels, supporting IMO Tier III compliance.
Q: What is the difference between 4307261 and standard exhaust thermocouples?
A: Offers 3x higher accuracy (±2°C vs. ±6°C) and longer life in extreme temperatures, ideal for precision aftertreatment control.
Q: Can it be installed upstream of the turbocharger?
A: Yes, the Inconel sheath withstands high-velocity exhaust gases (150 m/s), making it suitable for turbo inlet temperature monitoring.
Q: How is the sensor grounded to prevent EMI?
A: Integral grounding wire ensures low-resistance grounding, reducing signal noise in high-voltage hybrid environments.
Q: What is the minimum insertion depth requirement?
A: Recommended insertion depth is 50mm into the exhaust stream for accurate gas temperature measurement.
