OVERVIEW
What it does and why it is built this way
The LV-420 is a vibrating fork level switch. A piezo drive keeps the tines at resonance; when product covers them, the frequency drops and the switch trips.
It needs no calibration, ignores foam and viscosity, and offers a SIL 2 capable (demo) overfill-protection option.
KEY FEATURES
Maintenance-free point-level detection
Proof-test without removing the sensor
Adjustable switching delay
