LU10 series ultrasonic level switchDetailed product description：

Characteristics of LU10 series ultrasonic level switch

Reliable liquid level measurement can be performed on thin layers, suspensions, and various oils
Installation flexibility of two probe lengths
PP or PTA acid resistant plastic shell with anti-corrosion properties
The probe and cable with a protection level of IP68 can be used for operations below the liquid level in tanks and troughs
Relay or FET output can be conveniently interface with PLC, SCADA or Alarms
Optional normal on/off status

application
The LU10 series ultrasonic level switch can be applied to a wide range of applications, including liquids with mild layering, such as xylene acid and cooking oil
Technical Principles
The fork shaped probe of piezoelectric crystal is separated by air, and a crystal vibration frequency of 1.5MHz transmits ultrasonic signals to the air gap. When the probe is immersed in liquid, the crystal acoustic waves couple and the FET switch changes state.
