LVU-150-R Series

Ultrasonic Level Sensors

• Not Sensitive to Changes In Viscosity, Density, or Conductivity

• SPST Relay Standard

• Resists Vapor and Turbulence

• NEMA 6 (IP68) Submersible Sensor and Cable

Description

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 lls with liquid, the sonic wave passes

from one crystal to the other.
