Oil lubrication system

The Streak Sensing Unit is designed to detect oil traces in the air tube, down to 5mm3/min. The product has been designed using a primary/secondary concept. The primary sensor, while monitoring a single tail tube, also incorporates a 4-segment LED display, 3 soft keys for programming and configuring, and an M12 electrical connector for power supply and fault alarm output. The secondary sensors may be piggybacked to the primary sensor, up to a maximum of 3, or may be remotely connected via an interconnecting cable. One secondary sensor can monitor one tail tube. The sensors are designed for either 4mm or 6mm tube. The sensor works by detecting and counting pulses, generated from the oil particles in the air stream passing through optical components of the sensor. The count value is checked periodically and compared with the calibrated value. Should the count value fall below a certain predetermined point, then the unit will initiate an alarm. The calibrated value is the value as determined by a calibration sequence which is initiated by the user, on initial setup, and once a steady-state stream of oil can be clearly seen in the tubes. Various other parameters may be configured through the menu on the primary sensor. The sensors may be sold separately, as a kit, within an IP rated enclosure, or may come incorporated in an Air-Oil spindle lubrication system panel. On such a panel, the sensors have been designed to interface directly with the SureFire Lubricator with a controller.
