Water alarm WW 3/ WW 10 series - 1

The ingress of water into fluid power or lubrication systems reduces the life of oil significantly and causes damage to other components used in the systems. The most reliable method of detecting water in oil is to measure the interface level between water and oil when the water is separated. The BUHLER water alarm units have a float which rises in water but sinks in oil. It only takes a build- up of around one litre water in the sight glass to elevate the float and actuate a first contact to signal danger. The secondary contact warns that there is water in the tank. Water alarm units for intank installation are available upon ■ Reliable physical measuring system Buhler Technologies GmbH Internet: www.buehler-technologies.com e-mail: fluidcontrol@buehler-technologies.com
