The odometer sensor is generally  Hall Effect Sensor . You can use a multimeter to test resistance, or test continuity. We, one of the best  hall sensor suppliers  in China, will share you two ways of odometer sensor detection methods: 1. Remove the speed sensor connector plug and check the resistance value of the two lead wires of the sensor with the table resistor resistance, which should meet the standard requirements. 2. Rotate the output shaft of the transmission and use an automobile oscilloscope to detect the signal voltage waveform between the two leads of the speed sensor. The waveform is alternating current. The amplitude and frequency of the waveform increase with the speed of the output shaft. This indicates that the sensor performance is good. Nowadays, the odometer sensors are mostly electronic components. The odometer sensors generally have three wires, red, black (or orange), green (or other colors), red power cables, and black (or orange) ground cables. The

The important role of  Magnetic Sensor  technology in developing the economy and promoting social progress is very obvious. All countries in the world attach great importance to the development of this field. It is believed that in the near future, sensor technology will take a leap forward and reach a new level commensurate with its important position. The future development trend of magnetic sensors has the following characteristics: 1, high sensitivity. 2, temperature stability. 3, anti-jamming. 4, miniaturization, integration, intelligence. 5, high frequency characteristics. 6, low power consumption. It is believed that in the near future, sensors such as  Gas Meter Sensor  heat meter sensor energy meter sensor can be applied practically to each household's life to bring benefits to people.

In 1974, American physicist Wiegand found that the metallurgy of a properly processed alloy wire changes, the coercivity of its outer shell is much greater than the coercive force of the inner core, and it depends on the difference in magnetic properties and a certain amount of extraneous energy. The magnetic field conditions allow the magnetization direction of the core to be the same as or opposite to the magnetization direction of the housing, and this magnetization change can be repeated with a defined external magnetic field. This phenomenon is called the "Wiegand Effect." Wiegand Sensor  is precisely the magnetic sensor developed by the Wiegand effect. It consists of two parts: 1. The sensitive alloy wire; 2. The detection coil wound around the wire. When relative motion occurs between the measured magnet and the sensor, an appropriate external magnetic field acts on the alloy wire, the magnetization of the core jumps, and the detection coil outputs the induced volta

Gauss meters  quantify magnetic flux density. Gauss meters offer you a static dimension. The research is placed in the desired measuring place and the Gauss meter steps the flux density at the point. Every Gauss meter is completely capable of quantifying dynamic areas but it isn't a necessity of this measurement procedure to have a shifting magnetic field or surroundings. Gauss meters are great for measuring the flux density of air openings from loudspeakers, motors etc.. In such areas the regular density is uniform therefore probe position is not as significant. Gaussmeters will also be excellent at discovering local point effects since they have a very small detection area around the probe. Find trusted  Gauss Switch Wholesale .
