The 651 single point RF level switch provides basic, single-point switching for use as an alarm or level indication. It’s virtually immune to process coatings on the probe, making it a useful solution for many tough level applications. With no moving parts, the 651 single point switch with self test is well-suited for applications where other technologies struggle with accuracy.
