1. What are the types of flow meters? What are the types of ABS sensors for automobiles? The ABS sensor is a speed sensor, which can be classified into three types: magneto electric, Hall type, and photoelectric. However, the one applied to ABS sensors is usually magneto electric.; Magnetic electric ABS sensors can be divided into split type and integrated type according to their structure. Split type refers to the sensor and gear ring being separated (such as Volkswagen models). Integrated means that the sensor and gear ring are integrated as a whole (such as in the general model).; Among the various types of sensors, the common ones are:; 1. Intake pressure sensor: It reflects the change in absolute pressure inside the intake manifold and provides a reference signal for calculating the fuel injection duration to the ECU (engine electronic control unit); 2. Air flow meter: measures the amount of air inhaled by the engine and provides it to the ECU as a reference signal for fuel injection time; 3. Throttle position sensor: measures the angle of throttle opening and provides it to the ECU as a reference signal for fuel cut-off, fuel/air ratio control, and ignition advance angle correction; 4. Crankshaft position sensor: detects the crankshaft and engine speed, and provides it to the ECU as a reference signal for determining ignition timing and working sequence; 5 Oxygen sensor: detects the oxygen concentration in the exhaust and provides it to the ECU as a reference signal for controlling the fuel/air ratio near the optimal value (theoretical value); 6 intake temperature sensor: detects the intake temperature and provides it to the ECU as the basis for calculating air density; 7. Coolant temperature sensor: detects the temperature of the coolant and provides engine temperature information to the ECU; 8. Knock sensor: installed on the cylinder block to specifically detect the detonation condition of the engine and provide it to the ECU to adjust the ignition advance angle based on the signal.; These sensors are mainly used in transmissions, steering gears, suspensions, and ABS.; 10 Transmission: There are speed sensors, temperature sensors, shaft speed sensors, pressure sensors, etc. The steering gear has angle sensors, torque sensors, hydraulic sensors, etc; 11 Suspension: There are only rubber speed sensors, acceleration sensors, body height sensors, roll angle sensors, steering angle sensors, etc.; Additional Information:; There are three commonly used types:; 1. According to the physical quantities of the sensor pointer, it can be classified into sensors such as displacement, force, velocity, temperature, flow rate, gas composition, etc.; 2. According to the working principle of sensors, they can be classified into sensors such as resistance, capacitance, inductance, voltage, Hall effect, photoelectric, grating, thermocouple, etc.; According to the nature of the sensor output signal, it can be classified into: switch type sensors with output as switch quantity ("1" and "0" or "on" and "off"); analog type sensors with output; digital type sensors with output as pulse or code. Pressure sensors are mainly used to detect cylinder negative pressure, atmospheric pressure, boost ratio of turbine engines, cylinder pressure, oil pressure, etc. Suction negative pressure sensors are mainly used for suction pressure, negative pressure, and oil pressure detection. Pressure sensors commonly used in automobiles include capacitive, piezoresistive
