Bosch offers sensors for a wide range of different applications and use cases. The sensors have proven their capabilities within the automotive industry for many years and are widely used for different industrial and off-highway applications.

The range of products includes angular position, rotational speed, temperature, electronic battery, knock, air mass, inertial, lambda and pressure sensors. Many of these are available in specific variants to cover different use cases and physical phenomena.

Angular-position sensors

Steering angle sensors

The steering-angle sensor provides informtion about the steering-angle and slew rate of the steering-angle to numerous safety and driver assistance systems like: Electronic Stability Program (ESP), Advanced Front Lighting System, Electric Power Steering, Park Assist and Driver Drowsiness Detection.

Throttle valve angle sensors

Throttle position sensors are installed at the throttle valve to determine its position and angle. They measure the required data with high accuracy.

Rotational-speed sensors

Crankshaft sensors

Crankshaft sensors determine the rotational speed and the position of the crankshaft with high accuracy. These data are used by the engine control unit (ECU) to perform a precise injection and determine the right ignition timing.

Camshaft sensors

Camshaft sensors accurately determine the position of the camshaft. Their high measurement accuracy allows precise injection and accurate camshaft adjustment.

Temperature sensors

The temperature sensor measures the temperature of various fluid media, such as water, fuel, or oil, over a wide temperature range.

Battery Sensors

The electronic battery sensor (EBS) measures physical variables of the battery with a high degree of accuracy. The internal battery state detection (BSD) software provides information about the current battery state, as well as about the predicted future electrical behavior. By providing this relevant information, the EBS allows for the implementation of an optimized electrical-power management (EEM) system in the Off-Highway vehicle and supports fuel- and CO2-saving technologies such as start/stop, coasting or recuperation.

Knock sensors

Knock sensors reliably and precisely detect engine knocking, thus supporting the engine's performance and durability.

Inertial sensors

Interial sensors are a combination of yaw rate sensors and acceleration sensors. The rotation of up to two axis and acceleration in up to three directions can be measured by these sensors for various Off-Highway applications.

Pressure sensors

Manifold and boost pressure sensors

The manifold and boost pressure sensor enables fast and precise measurement of the pressure and temperature of the intake air of combustion engines. Hence, it supports the exact regulation of the fuel quantity.

Differential pressure sensors

The differential pressure sensor monitors the differential pressure of the particle filter to provide information about its charge status. Consequently, the differential pressure sensor provides the foundation for a demand-based particulate filter regeneration.

Oil and fuel pressure sensors

The oil and fuel pressure sensor ensures rapid and highly precise measurement of fuel and oil pressure in every kind of combustion engine (gasoline, diesel, CNG, LPG) and transmission. This measurement is used to control the amount of fuel or oil supplied by the pump.

High pressure sensors

The high-pressure sensor measures the fuel pressure within the fuel rail of diesel direct injection engines. The engine control unit requires this information for the exact dosing of the fuel quantity to be injected. The sensor version for natural gas (CNG) measures the pressure inside the pressure regulator module.

Airmass sensors

Bosch air mass meters quickly and precisely measure the actual air mass flow rate for an optimized air-fuel mixture, supporting an efficient fuel combustion and powerful engine performance.

Lambda/Oxygen sensors

Invented by Bosch in 1976, Lambda sensors have made a significant contribution in order to fulfill current emission standards. To date Bosch has produced more than one billion lambda sensors.

By measuring the oxygen content of the exhaust gas, the lambda sensor supplies the necessary information for the right air/fuel mixture to the engine control unit and supports a powerful engine combustion.
