Oil Detectors

Gestra offers conductive oil detection alarms for cooling water system monitoring as well as turbidity monitoring systems based on the photoelectric measuring principle. These products are mainly used in industrial boiler and food and beverage applications, where they accurately detect oil and insoluble contaminants that have entered condensate return or other transparent liquids. When selecting a model, pay close attention to the fluid medium, operating temperature, pressure rating, and the explosion protection and installation requirements of the specific monitoring environment.
