OMEGA’s ultrasonic sensors deliver
accurate and reliable liquid level
detection with an SPST mechanical
relay output. The technology
provides a high level of ultrasonic
sensitivity, including resistance to
vapor and turbulence. The
ultrasonic sensor utilizes a
fork-shaped sensor which contains
two piezoelectric crystals, one of
which acts as the ultrasonic
transmitter, and the other as a
receiver. If the air gap between the
points of the fork fills with liquid, the
sonic wave passes from one crystal
to the other.
