Type WW3 & WW1O

Perfect for operation between 43.5 and 145 psi, the Bühler water alarm range notifies instantaneously of the presence of water in a hydraulic system.

The entering of water into fluid power or lubrication systems significantly reduces the life of oil and causes damage to other components used in the systems. The most reliable method of detecting water in oil is to measure the interlace level between water and oil when the water is separated.

The Bühler water alarm units have a float which rises in water but sinks in oil. It only takes a build-up of around one litre of 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 in-tank installation are available upon request.
