Straight Hair Motor Exhaust Temperature Sensor

The exhaust temperature sensor is a sensor that detects the exhaust temperature of the engine, which measures the temperature in the exhaust pipe and passes this data to the car's computer system. The exhaust temperature sensor is usually located in the exhaust pipe in order to measure the exhaust temperature, and this data can be used to monitor the operation of the engine and adjust it if necessary. The exhaust temperature sensor is an important part of the computer system of the modern car, which can help the driver to maintain the optimal operation of the engine and ensure the safe operation of the vehicle in the high temperature environment.

    Features

    1. Flexible insertion depth, from 25mm to 70mm by the customer
    2. Linear and vertical structure, 0° and 90° customized by customers
    3. A wide temperature range can be measured by a temperature sensor
    4. Through the thermal decoupling process, 850° absolute precision can be achieved
    5. Standard linear curve
    6. Short response time
    7. Long-term high stability
    8. The test principle is simple

    Application

    Control and monitor engine components (valves, branches) and external temperature sensing elements (exhaust gas recirculation EGR). Diesel particulate filters and catalysts);
    The temperature measurement is combined with the on-site diagnostic system (OBD), for example, to detect the ignition temperature of the catalyst; Control and monitor heat storage in black smoke filters (PDF) and selective catalytic reduction (SCR);
    Measurement of exhaust gas recirculation (EGR) temperature and turbocharger temperature;
    Temperature is monitored to ensure maximum catalytic efficiency.
    Mainly applicable to Dongfeng, Cummins diesel engine.
