LZ12 series tuning fork type liquid level switchDetailed product description：

Characteristics of LZ12 series tuning fork type liquid level switch

Can be applied to liquids and lighter solids (including particles and powders).
Relay or FET switch output can be connected to PLC, SCADA or alarm, which is a way to measure the liquid level of more challenging layered, corrosive or suspended liquids.
The plastic structure of PP/Ryton material has anti-corrosion properties
IP68 or NEMA6 probes and cables can be used for underwater operations in tanks or troughs
Optional normal on/off status

Application of LZ12 series tuning fork type liquid level switch
An excellent choice for challenging liquids, including industrial liquids such as sodium hydroxide, saltwater, copper sulfate, etc
Technical Principles
The vibration frequency of the tuning fork switch is 400Hz, and the frequency changes when the switch enters a liquid or suspended medium. When the measured frequency change reaches an appropriate value, the relay change state indicates the condition of the medium.
