Lenord+Bauer’s new SEI10 – 2 channel speed sensor
The new SEI10 sensor is a further development of Lenord+Bauer’s industry leading GEL 247 series found extensively in rail vehicles, such as trains, boggies, cranes, amongst others.
It has been designed specifically for speed and position detection in on- and off-road industrial vehicles, agricultural vehicles, and heavy machinery.
Detection is achieved due to the changing magnetic field, created when the movement of a ferromagnetic target wheel is captured by the contact-free sensor.
The sensor has two independent differential channels. The sensor is able to eliminate the effects of magnetic and system offsets and detect false output transitions caused by vibrations in electric motors at startup and low speed. There are different signal output patterns to control rotational speed and direction of rotation with high accuracy.
Advanced calibration techniques are used to optimize signal offset and amplitude. This makes the sensor very insensitive to variations in air gap, speed and temperature.
The sensor is available for a variety of applications requiring two-phase rotational speed and position signals or simultaneous high-resolution rotational speed and direction information. Selectable error detection mode options are available upon request to realize ASIL B, ASIL B (D), SIL 2 or 3 applications.
