UZY-100S tuning fork level switch is a new level switch. Instrumentation consists of a transmitter and amplifier components fork, fork root compression in two piezoelectric crystals, a group as the driving Actuator driving fork vibration, the other group as a detector for converting the voltage signal into the prongs. When the prong is blocked, the amplitude of the vibrator is small, the vibration frequency is changed, the relay Output switching signal. In order to achieve level limit measurement. Sensors made of 316 stainless steel, corrosion resistant mild for limit controllers and high / low alarm.
