Vibrating level switch / for liquids - max. 45 bar, max. 130 °C | NWS
The product is the KOBOLD Liquid Level Switch and the model is NWS. It works on resonance frequency or the principle of the tuning fork. The excitation and monitoring of the actual oscillation frequency will be achieved by a piezoelectric crystal. The switch can be used in various types of vessels and pipelines because of its two and three wire design. Changes in output signal are detected and represented electronically when the fork is immersed in liquid which operates the switch. With an option to connect the NWS to a PLC through a third terminal, the product operates as a 2 wire switch with the load. The special feature is the LED optical confirmation when the switch is in use in the correct condition.
