CG-1NH CG-2NH CG-1FH CG-2FHEasy programming by push buttonsMultifunctional with microcomputerFirst level switch to have status indicating LCDImproved buildup prevention performanceExtremely reliablePrinciple of OperationSet range is divided into 8 segments, and ON/OFF points are set for the segments. Hysteresis is also programmable.The basic oscillator circuit is of the parallel resonance circuit with L (coil) and C (capacitance between the electrodes).The oscillation frequency (f) of this circuit is : f = 1/2 ? ?LC.The frequency without material around the sensor (f1) is: f1 = 1/2 ? ?LC, where C is the capacitance without material around the sensor (zero point).With material around the sensor, the capacitance increases (C+?C), and the frequency (f2) is: f2 = 1/2 ? ?L(C+?C), where C+?C is the capacitance with material around the sensor (span point).The sensor detects the frequency change from f1 to f2, and actuates the relay. The frequency range is divided into 8 segments (between zero and span), and the set and reset points assigned on a desired segment, which means high limit, low limit and hysteresis can be programmed.
