Hall Effect High Specification Throttle Pot Sensor, Left Hand
Hall Effect High Specification Throttle Pot Sensor with D-Drive
SBD have developed a hall effect sensor with Variohm for use with our throttle body systems. The calibration has been set up to match the output range of the standard sensors we supply. Being a contactless type sensor, there is no track to wear out, so gives improved durability. This is a left hand version, shown below on our XE display engine.
Advantages & Disadvantages of track & hall effect throttle position sensors
Care should be taken when selecting a sensor type to use because there are advantages and disadvantages with both types of sensor.
Hall Effect sensors have a small processor and although the sensors are contactless so there is no track to wear out, it can be affected by strong magnetic fields or large electronic pulses, which can cause the sensors to reboot. If the processor does fail, there will be no output from the sensor at all.
Contact position sensors have a track that wears out over time and with age will become less efficient, but the user will see the efficiency degrade when checking, very rarely do they fail completely and will allow the user in most applications to continue running until the sensor is replaced.
