LVU2718-B_G_LVU2732-B_G超声波液位变送器OMEGA
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.
OMEGA’s LVU2700 ultrasonic level transmitter provides continuous level measurement up to 10 m (32.8') with a 4 to 20 mA signal output, and is configured via free software and a USB adaptor. This non-contact liquid level sensor is ideally suited for corrosive, ultrapure, sticky or dirty liquids, and is broadly selected for bulk storage, day tank, lift stations and process tank level applications.
