The Robertshaw® Mini-Tek Liquid Level Detector is used to detect the levels of liquids in major diesel engines. The Robertshaw Mini-Tek operates on the electrostatic or capacitance sensing principle. The probe portion of the unit, extending into the liquid, produces a change in electrical capacitance when liquid displaces the air immediately surrounding the probe. The Robertshaw Mini-Tek detector will provide warning when liquid levels reach approximately 50% of capacity. This provides time to take action before damage is done to the engine. The Robertshaw Mini-Tek comes in three different models. Model 613 Coolant Level Detector, Model 614 Hydraulic Oil or Fuel Detector, Model 624 Motor or Gear Fuel or Oil Detector.
