When the material and sensor rods at contact, vibration signal is becoming smaller, until stop resonance, control circuit output electrical contacts will signal. O single vibrating head firm structure, no need to correct, use simple o can be expected to remain in vibration of the rod material, not wrong in the earthquake drop action o for high viscosity and low density, the float switch, electrostatic capacitive switch, resistance screw vane switch can't the testing of material, the most suitable for use o use power output capacity, 110/220 VAC contact 5 A / 250 VACSPDT o junction box material: aluminum alloy NEMA4/12, IP65; Sensor rods material: SUS304 o king in place of the threaded for 1 1/2 "NPT; into the line for mouth 1/2" PT, PG13.5 o sensor rods material induction density: the lowest 0.03 g/cm? O have cable type, lengthened, separation type, standard four are available. Single fork can widely applied in all kinds of different density, humidity composition
