La description

Sensors from GEMS Sensors, a US company founded in 1955 in Plainville, CT, are well-known in the industrial world due to their unbeaten technical characteristics and superior response time. They are used to control and measure the levels and flow of various liquids in different industry sectors. The sensors are manufactured at three production sites in North America, Europe and Asia.Externally adjustable for water, oils and gases. These externally adjustable switches are ideal for protecting machine tools from coolant flow failure, for protecting bearings from loss of lubricant or to assure proper air flow. They offer an infinite number of flow settings at pressures up to 1000 PSIG, with low pressure drop and precise repeatability. The adjusting vane is easily field adjustable using an ordinary flat-bladed screwdriver. The adjustment is set-screw-locked for tamper-free operation after field calibration.''
