Monitoring critical lubrication points

Sensor from IPF avoids expensive damage due to premature wear

With the SY991185 IPF presents a sensor that can be used to monitor the lubricant flow in lubricant lines.

The robust device in a space-saving, cuboid aluminum housing (IP67) monitors the lubricant supply to bearing points on machines and systems, preventing possible cost-intensive damage due to premature wear of components. The SY991185 clearly recognizes whether the lubricant (e.g. oil or fluid grease) metered by the metering valve has actually been delivered to the lubrication point.

Thanks to its dynamic measuring principle, the sensor detects even the smallest dosing quantities ≥5mm3 for lubricating oils. The integrated contactless position sensing of the measuring piston also enables fast reset times and thus dosing cycle monitoring of up to two lubrications per second. The sensor can optionally be equipped with an additional evaluation unit to provide an instant error signal in the event of insufficient lubrication.

The installation of the SY991185 is very simple: cut the feed line to the lubrication point to be monitored and attach the open ends of the line to the device using M8 union nuts. The electrical connection of the sensor, which is pressure-proof up to 70 bar, is made using a 3-pin M8 connector.
