As demands for higher efficiency, increased safety, and improved driver experience continue to push the automotive market, the need for more sensors and active monitoring of the various systems in the vehicle are needed. To meet the often times harsh environments, high temperatures, and dynamic pressure environments found in these systems of the vehicle, SMI has developed a series of cutting edge, high performing products to address these demanding applications.
Tire Pressure Monitoring Systems (TPMS)
Tire Pressure Monitoring Systems (TPMS) are mandated in many countries due to their impact to inform drivers on vehicle safety and fuel efficiency
As a critical component in the operation of a vehicle, the transmission performance will directly influence the performance of a vehicle.
Exhaust Gas Recirculation (EGR)
Exhaust gas recirculation is a technique utilized to reduce emissions by dropping the in-cylinder temperature during combustion.
Barometric Absolute Pressure (BAP)
Barometric pressure sensing helps the engine manage the proper air to fuel ratio to optimize power and efficiency during operation.
Liquefied Petroleum Gas & Compressed Natural Gas (LPG&CNG)
As alternative fuel sources increase due to emissions regulations, liquefied petroleum gas (LPG) and compressed natural gas (CNG) are becoming increasingly utilized in vehicles around the world.
Engine oil is crucial for a vehicle performance and reliability.
Manifold Absolute Pressure (MAP/TMAP)
Manifold absolute pressure sensors (MAP) are used to measure the manifold pressure to determine the air density to calculate the engine’s air mass flow rate.
Diesel Particulate Filter (DPF)
Diesel particulate filters (DPF) are used to remove particulate matter from the exhaust gas of a diesel engine.
Gasoline Particulate Filter (GPF)
Gasoline particulate filters (GPF) are used to remove particulate matter from the exhaust gas of a gasoline direct injection (GDI) engine.
Occupant detection sensors help your vehicles safety systems operate more accurately particularly for seat belt alert systems and air bag deployment.
Fuel Vapor Pressure/Evaporative
Fuel vapor or evaporative pressure sensors are used to ensure the gas tank is properly sealed and that vapors are not escaping into the atmosphere.
Air Conditioning (AC)
Air conditioning has become a key luxury feature in most cars today, as customer demand for such systems strengthens.
Brake boosters are used to enhance the driving experience and make pushing the brake easier for drivers.
Crank Case Pressure
During ideal operation the pressure in the crankcase should remain low.
It is quite often that truck braking systems are designed using compressed air brakes.
For high-end passenger vehicles and trucks, air suspensions systems offer a more comfortable and stable ride.
