We are about to release a new proximity sensor able to detect bearing wear on large
2-stroke diesel engines.
The principle is that when the bearing wear is abnormal or if some bearing metal
cracks and disappear, the crosshead will move downwards. The movement will be detected
by the proximity sensor. When the crosshead is in BDC - bottom dead center, the
proximity sensor will measure the distance to a signal developer that is mounted
on the crosshead pin. The main-, crank- and crosshead bearings can all be monitored
if a proximity sensing system is installed. However, to obtain the best possible
bearing monitoring solution we will offer the proximity sensor in combination with
our well proven range of main and crank bearing temperature sensors.
Stand alone and integrated
The bearing wear detection system will be delivered both as a stand alone solution
and as an integrated part of the DataChief C20 alarm, monitoring and control system.
We will also design an easy to install refit solution for vessels where the DataChief
C20 is already installed.
- Measurements are done when the crossheadi is in BDC
- The gap between sensor and signal developer is 25 -30 mm
- One sensor is installed on either side of the crosshead
- All signal processing is done internally in the sensor
- The sensor has CAN open output
