Kobold OVZ Flowmeter Case Study

Heavy duty equipment needs protection you can count on

Cone crusher lubrication monitoring

Mobile cone crushers are used to turn raw materials such as rocks, minerals, ores, reclaimed glass and ceramic into graded usable product. They are versatile and convenient, producing the materials needed for construction at the place where they are needed, saving time and cutting down on transport costs on large civil, mining and recycling projects.
The rocks are fed into a fixed cone which has a rotating eccentric cone inside it. By varying the gap between the cones, the size of product produced can be controlled. At the heart of a mobile cone crusher is the bearing assembly. This is subject to massive pressures, and vibrations, and the machines are used in harsh climatic conditions throughout the world, day in day out. The bearing assembly is very expensive, is often time consuming to replace and subject to a long delivery time. Correct lubrication of the bearing assembly is therefore paramount to avoid costly downtime. Therefore a dependable means of monitoring the oil supply is required, that will work in extremes of temperature, and be as rugged and as reliable as the rest of the machine.

The OVZ flow monitor

Solution: The OVZ flow monitor from Kobold

The OVZ flow monitor from Kobold ticks all the boxes. It has a robust durable aluminium body and PMMA cover, which acts as a sight glass, allowing engineers to see at a glance that all is well with the precious oil flow. Its positive displacement technology means that it is viscosity compensated when subjected to temperature extremes. The electronics have been epoxy encapsulated for full protection from ingress or vibration. They combine a wide voltage supply range, DC-DC convertor with interference filter, for a consistentĀ output signal allowing optimal lubrication control.

The OVZ offers great value insurance and accurate, reliable performance.
