Variable Reluctance (VR) Speed Position Sensors |
|
| Using
this sensor signal, the engine control unit can calculate the
engine speed and compute the injection as well as the ignition
timing. Contactless sensing guarantees wear-free operation and
complete encapsulation protects the sensor from operating fluids,
dirt and water. These sensors can be installed in an axial or
radial alignment to their target, and can be supplied with an
integrated connector or with a cable and connector. |

| Pressure Sensors |
|
|
|
|
MAP:
Manifold Absolute Pressure Sensor
T-MAP: Manifold Absolute Pressure Sensor with Temperature Sensor |
|
A MAP sensor measures the intake air pressure in
the manifold as a basis of determining the intake mass airflow. A
T-Map sensor also measures temperature of the air entering the
engine. This information is used to calculate the quantity of fuel
to be injected for the proper air-fuel mixture. The dynamic
measurement capability of this engine management component is
critical to the EMS System’s ability to reduce engine emissions.
Turbocharged versions of these sensors are also available. |

|
| BAP: Barometric Absolute Pressure |
|
| This sensor is used where engine
control unit requires additional altitude compensation information |
 |
| |
|
| Temperature Sensors |
|
These temperature sensors are used
for measurement of air, water, fuel, oil and most other engine
fluids. Cylinder head temperature sensors are also available. More
than 400 variants are available from Continental.
These sensors use the NTC (Negative Temperature Coefficient)
technology: Resistance of the temperature sensor decreases as
temperature increases.
|
 |
| |
|
| Knock Sensor |
|
Advanced engine designs with high
compression ratios can lead to increased knock that can damage the
engine.
Knock Sensors constantly measure structural vibrations in the
engine to allow dynamic adjustment of the ignition parameters
during operation. Continental’s Knock Sensors are broadband
sensors which are increasingly replacing resonance sensors in the
industry.

| Active Speed Sensors |
|
In contrast to inductive
Speed/Position Sensors, these sensors use the Hall effect
technology to provide a digital output signal for measure of
crankshaft or the camshaft position, or for the speed of a shaft.
This is used by the engine management system to control both
injection and ignition timing, and make variable valve control
possible.
For valve control, the system needs additional camshaft position
information supplied by the Active Camshaft Position Sensor.
A Active Transmission Speed Sensor measures the gearbox speed, the
vehicle speed and the engine speed. |

|
| Integrated Mass Airflow Sensor (SIMAF) |
|
The Continental Integrated Mass
Air-Flow (SIMAF) Sensor is used to measure the mass-flow of fresh
air entering the engine. The mass air-flow measurement is combined
to other sensor information used to regulate fuel delivery to the
engine. The MAF sensor also provides important diagnostic
information and improves vehicle drivability.
The Continental sensor is designed to be easily integrated into a
custom housing such as a throttle body, for example.

 |
| |
|
| Torque Sensor |
|
Continental has developed a
non-contacting, non-compliant torque sensor which, by design, is
mechanically robust, highly reliable and extremely accurate. The
sensor was developed for use in vehicle drivetrain applications.
The sensor provides a means to accurately measure the magnitude
and polarity of the torque applied to a shaft. It has the ability
to survive extreme torque exposure without detrimental effects.
The contactless measurement technique adds to the robustness of
the overall system design. |

| Passive Oil Level Switch |
|
Applications: Low level engine /
transmission oil warning
Gives an open/short circuit signal depending on whether the
measured fluid is higher/lower than a given height. |
 |
| |
|
| Passive Electro-thermic Oil Level
Sensor |
|
Applications: Engine / transmission
oil level monitoring
For non-conducting fluids (e.g. oil), giving a linear analog
(voltage) level signal based on the electro-thermic principle.
|
 |
| |
|
| Active Fluid Switch |
|
Applications: Condensed Water
Detection, Low Coolant Water Level Warning
This sensor is used with conductive fluids (e.g. water) and gives
a digital high/low signal depending on whether the fluid is
present or not. |
