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.Intrinsically Safe SAFE-PAK® Relays amplify sensor load-handling capabilities. Costly explosion-proof enclosures with their mounting requirements are unnecessary. No purging is required. Low Sensitivity SAFE-PAK: Sensor closures up to 1000&Omega, resistance control resistive loads to 5A at 120 VAC. 120 VAC, N.O. model.''
