Maintenance indicators serve the purpose of monitoring filters by indicating the exceedance of a pressure differential and/or a back pressure in the filter. By default, the Rexroth filters are supplied with a mechanical optical maintenance indicator. The electronic switching element is available as accessory and compatible with any mechanical optical maintenance indicator.
