Sensors

These sensors are designed to measure absolute air-pressure, especially the air box pressure of gasoline or Diesel engines.

An integrated circuit combines a piezo-resistive sensor element and an electronic for signal-amplification and temperature compensation. The output of the sensors is an analog, ratio metric signal.

These sensors are designed to measure the absolute or relative pressure of various kinds of media e.g. Diesel, gasoline, water, engine oil, transmission oil or air.

The sensors use stainless steel measuring cells with piezo-resistive measuring bridges in thin layer technique. These are hermetically welded together with stainless steel pressure ports. This guarantees a complete media compatibility.

The main benefit of these sensors is the high quality of a production part at a low price.

A knock sensor is used for detecting structural born vibrations in spark ignition engines due to uncontrolled combustion. It is suitable for operation in extreme conditions.

Due to the inertia of the seismic mass, the sensor moves in correlation to the engine block vibration; this motion results in a compressive force which is converted into a voltage signal via a piezoceramic sensor element. As a result, upper and lower voltage thresholds can be defined directly correlating to an acceleration magnitude. The main benefits of this sensor are its robust mechanical design, compact housing and precise determination of structure-related noise. The small packaging is accomplished by integrating the connector directly to the sensor.

Lambda sensors are designed to measure the proportion of oxygen in exhaust gases of automotive engines (gasoline or Diesel).

The wide band lambda sensor is a planar ZrO2

dual cell limiting current sensor with integrated heater. Its monotonic output signal in the range of lambda 0.65 to air makes it capable of being used as a universal sensor for lambda 1 measurement as well as for other lambda ranges. The connector module contains a trimming resistor, which defines the characteristic of the sensor.

The main benefit of our Lambda Sensors is the robust design combined with the high Bosch production quality standard.

Our combined pressure sensors not only measure the air pressure, but also the temperature of the surrounding medium. Therefore one component less is needed and valuable weight saved.

This sensor is designed to measure rotational movement of throttle position.

The electrical circuit is designed with a magnetic rotary sensor using a Hall element and digital signal processing; sensor output is ratiometric. The angular position is provided by a two pole magnet integrated in the sensor shaft.

The main benefit of this sensor is its contactless Hall effect technology and its robust design for motorsport applications which includes fully redundant power and ground.

Our speed sensors are either working inductive or according to the Hall principle. They acquire the rotational speed of wheels, camshafts, crankshafts and turbochargers.

Temperature sensors are designed to measure temperatures of oil, water, fuel or air. This signal is used as a control value for engine control units or as a measurement value which is logged in a data acquisition system.

The NTC-sensing element has a negative temperature coefficient. This means, that with increasing temperature the conductivity rises and the resistance decreases.

These kind of sensors were designed to measure the physical effects of rotational and linear acceleration. In order to achieve this, the acceleration sensor includes MEMS measuring elements connected to an appropriate integrated circuit.

A rotational acceleration around the integrated sensing elements generates a Coriolis force which changes the internal capacity of the micro machined sensing parts.

Furthermore, a pure surface micro machined element is used to measure the vehicle linear acceleration in all 3 axis. This combination of rotational and linear acceleration sensors enables a precise measurement of the vehicle dynamics.

The main feature and benefit of this sensor is the combination of 3 linear and 2 rotational accelerometers and its high speed 1 Mbaud CAN-signal output.
