YUASA M&B Industrial Grade Core Sensor Chip
Stable temperature signal conversion, low failure rate, strong anti-interference against vibration and electromagnetic interference in engine room.
Ship Inspection Standard Replacement Spare Part
Meets marine industry maintenance standards, supports CCS ship survey inspection, ideal stock spare part for shipping companies and chandleries.

Working Principle
This digital exhaust temperature indicator adopts high-precision thermocouple temperature sensing technology:
1. The stainless steel probe is inserted into the engine exhaust pipeline to collect real-time flue gas temperature;
2. High-temperature temperature signals are transmitted to the digital display host via heat-resistant braided
    cables;
3. The YUASA M&B core chip converts thermal signals into digital values, displayed directly on the LCD screen
    without mechanical pointer parallax error;
4. Real-time monitoring exhaust temperature data to judge diesel combustion efficiency, abnormal overload,
    exhaust pipe blockage and cooling system failure, preventing cylinder damage, turbocharger burnout and
    other severe engine faults.

Application Scenarios
1. Main Engine of Commercial Vessels — Exhaust temperature monitoring for Yanmar diesel main engines on 
    cargo ships, tankers and fishing vessels
2. Marine Auxiliary Generator — Real-time exhaust temperature detection for shipboard Yanmar auxiliary power
    generators
3. Yachts & Small Working Boats — Replacement spare instrument for Yanmar engines on yachts, patrol boats
    and engineering workboats
4.Ship Repair Yards & Marine Chanderies — Inventory spare parts for ship maintenance and vessel overhaul
   replacement
5. Offshore Platform Power Units — Exhaust temperature measurement for Yanmar diesel power equipment on
    offshore platforms

Installation & Maintenance

Installation 

1. Screw the stainless probe into the reserved threaded port of the engine exhaust pipe, tighten properly to prevent flue gas leakage;
2. Route the metal braided cable along the pipeline fixing clamp, avoid direct contact with high-temperature exhaust wall surface;
3. Fix the digital display host on the engine console or monitoring panel, connect the cable plug tightly;
4. Power on to test, LCD screen will show real-time exhaust temperature within 3 seconds.

Daily Maintenance

1. Regularly check the probe thread for carbon accumulation, clean carbon deposits to ensure accurate temperature measurement;
2. Inspect the metal cable surface for abrasion, avoid sharp metal friction cutting the wire;
3. Keep the digital display host away from water splash and heavy oil pollution;
4. If temperature reading jumps abnormally, check plug connection and probe aging status. 

Acceptance Standard

1. Visual inspection: Complete set including display host, temperature probe, heat-resistant cable and original packing box; surface without scratch, deformation or oxidation;
2. Part number verification: Product marking and carton label consistent with OEM No.150633-91348;
3. Temperature test: After installation, temperature response within 3 seconds, stable data without drastic fluctuation;
4. Matching test: Thread size fully fits Yanmar original exhaust pipe interface without gap or leakage after installation;
5. Packaging mark: Carton printed Japanese label 補用，consistent with original Japanese spare part packaging standard.
