Senmol Automotive Pressure Sensor

Pressure sensors could measure the temperature and pressure of various fluids (such as intake air temperature, port pressure, cooling water temperature, and fuel injection pressure, etc.).There are sensors to determine the speed and position of various parts (such as vehicle speed, throttle opening, camshaft, crankshaft, gearbox angle and speed, exhaust gas, and EGR position, etc.). also sensors for measuring engine load, knock, misfire and oxygen content in exhaust gas; sensors for determining seat position; wheel speed, road height in anti-lock braking systems and suspension adjustment Differential and tire pressure sensors; to guarantee the front passenger airbag, more than just more crash sensors and acceleration sensors are needed. In the face of factory-supplied side volume, overhead airbags, and more refined side head airbags.

Sensor Automotive Product Features

  • Adaptable The driving environment of automobiles is complex, and the automotive sensors are required to have strong environmental adaptability and resistance to harsh environments.
  • Strong Anti-interference AbilityFor example, high temperature, vibration, high-voltage electrical pulse, etc., will interfere with the sensor signal, and the car sensor must be able to resist various interferences generated by the car.
  • Cost-effective As cars become more and more electronic, intelligent, networked, and unmanned, more and more sensors are used in cars, reaching hundreds. This requires that automotive sensors must be cost-effective, otherwise it will be difficult to popularize and use in large quantities.
  • High Stability And ReliabilityThe characteristics of automotive sensors have a very large impact on the automotive electronic control system, and must have high stability and reliability.

Application Of sensor automotive In Different Industries

1.Automotive pressure monitoring sensor900600

Auto & Motorcycle Accessories

There are many sensors on cars and motorcycles, and cars and motorcycles also rely on sensors to work. The sensors detect signals and feed them back to their computers, and the computers control the corresponding parts to work. If the sensor is damaged, the corresponding component will not work properly, and therefore the car and motorcycle will not work properly. The functions of these sensors vary, enabling field-testing, ease of use, peak recording capabilities, and automatic identification.

1.Engine Oil Pressure Sensor-Senmol 900600

Engine Oil Pressure Sensor

The function of the engine oil pressure sensor is to detect the size of the engine oil pressure, which is generally screwed in the oil passage of the cylinder block through screws. It can monitor the oil pressure state of the vehicle in real time. When the oil pressure is insufficient, the pressure sensor will transmit an electrical signal to the ECU, and the ECU will light up the fault light to inform the driver.

2.Braking System-Senmol 900600

Braking System

With the development of braking technology, traditional hydraulic braking technology will inevitably be replaced by brake-by-wire, which is also in line with the development of automobile electrification, intelligence and automation. Automobile brake alarm sensor is an important part of automobile braking system. It can be widely used in mainstream cars at home and abroad to play an alarming role. When the brake pads are worn to a certain extent, the brake sensor will alarm and prompt to replace the brake pads.

3.Refrigerant Pressure Sensor-Senmol 900600

Refrigerant Pressure Sensor

The refrigerant (refrigerant) in the air conditioner has a high working frequency, and some refrigerants are flammable and explosive. Therefore, a pressure sensor is usually installed on the high-pressure pipeline between the air conditioner compressor and the condenser. According to the size of the refrigerant pressure Detect the amount of refrigerant and the operation of the compressor, and cooperate with the temperature sensor to control the operation and shutdown of the air conditioning system.

4.Car Fuel Pump-Senmol 900600

Car Fuel Pump

Considering the problems of heat dissipation, sound insulation, air resistance, etc., the fuel pump is currently built in the fuel tank. pressure. The oil level sensor is connected to the gasoline pump, the gasoline pump control unit and the fuel gauge by a line. If any fault occurs, it may be displayed on the instrument panel. Generally, the engine fault light is on and the fuel gauge is out of order.

5.Car Air Conditioner-Senmol 900600

Car Air Conditioner

Automobile air conditioning system mainly includes refrigeration system and heating system, ventilation system and air purification system. The work of the air-conditioning refrigeration system is the process of continuous gasification and liquefaction of the refrigerant. With the center of the compressor and the expansion valve as the boundary, the entire refrigeration cycle can be divided into two parts: high and low pressure. These all require sensors.

6.Fuel Pressure-Senmol 900600

Fuel Pressure

The fuel pressure sensor, also called the fuel pressure regulator, is used to control the fuel pressure in the fuel circuit, maintain a constant fuel supply pressure to the injector, and return excess fuel to the fuel tank. Oil pressure sensor is an important sensor for measuring the oil pressure of automobile engine, and its reliability is directly related to the safety of automobiles and people.

7.Coolant-Senmol 900600


The temperature sensor, which is installed in the water jacket of the engine block or the coolant line, is in contact with the coolant, and is used to detect the coolant temperature of the engine. After the ECU receives the temperature signal, it corrects the fuel injection time and ignition time. When encountering the failure of the coolant temperature sensor, first confirm the failure phenomenon, then analyze the cause of the failure, and then use the diagnostic computer to read the data flow related to the failure.

8.SCR System-Senmol 900600

SCR System

The working principle of SCR is that under the action of a catalyst, a reducing agent selectively reacts with NOx in the exhaust of marine diesel engines and generates non-toxic, non-polluting nitrogen and water. According to the system, it is divided into: air system, urea system, exhaust gas heating system and control system.




Senmol has its own design and R&D base, a single office building, and several semi-automatic and fully automatic production lines. Many researchers and operators. It has offices in Wuxi and Shenzhen respectively.
