Hydraulic Pump Control

The guys from Osbit and Hyserve brought this heavy-duty test rig into our workshop. We’re helping them develop a hydraulic pump control system, this is using a 5kW series wound motor to drive the pump which will be used in an off-shore application. They need to be able to limit the system pressure by using a hall sensor to detect and limit the motor speed. We’re using one of our Pro-360-HCs which has a hall input. Initially the sensor gave strange readings but we tracked this down to the hex heads of the bolts being used to trigger it. 5 minutes with a hacksaw and the system was running smoothly.
