ABB turbocharger speed sensor
The turbocharger speed sensor is a magnetic type and it does not
require any supply voltage. The sensor is mounted eccentrically
in the turbochargers bearing space cover. In a lubricating wheel
on the shaft there are six embedded magnets, which are each
generating a pulse in the sensor when passing the sensing head.
The sinusoidal signal from the sensor is thus proportional to the
rotation speed of the charger, and connected to the WECS.
The metal housing of the sensor is M12 x 1.25 mm. The cable is
connected by means of a four pole Euchner BS4 connector.
To install the sensor screw carefully the sensor completely in
by hand. Unscrew it 2 revolutions for a sensing distance of 2.5
mm, and tighten the counter nut well with a spanner.
Note!
The engine must not run while the sensor is mounted.
