In a machine tool, coolant and lubricants must always be available in sufficient quantity and reserve. Balluff’s BCS capacitive sensors are the ideal limit sensors for these media. Whether in direct contact or with no contact, they provide exact results and detect the minimum and maximum levels through the media container wall or with the use of adapters. They compensate for moisture, foam, and deposits of any kind, even through glass and plastic walls up to 10 mm thick. This enables them to reliably monitor the levels of coolants and lubricants.
