SEA SWITCH IIThe Sea Switch Two was designed and patented for all tank applications. The Sea Switch Two offers a reliable solution for liquid level detection, control for cargo, ballast, and storage tanks, without any moving parts.The Sea Switch Two uses a fully static system that is based on the propagation of an acoustic wave into a metallic rod. A piezo-electric sensing element produces a wave along the rod.As the liquid reaches the sensing element the oscillation stops and the alarm is activated.The Sea Switch Two sensor detects high, high-high, or low level in any liquid with an alarm output given by a dry contact or current loop change 6-18mA.Self-test built-in Fully static system - no moving parts Easy installation No calibration needed The Sea Switch Two can be installed either horizontally or vertically.Options: On deck displays Pump shutdown
