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.Series 19MR controls are the ideal choice where pump up or pump down service is necessary. This control eliminates the need for contactors because it can directly handle motors up to 1 HP at 120 VAC, or motors up to 2 HP at 240 VAC.''
