LFUD102 — remote head and ultrasonic blind zone
LFUD102 is a separated-probe non-contact ultrasonic level transmitter, with manufacturer head ranges up to 30 m and a model-dependent 0.25–0.8 m near-field blind zone. Position the sensor above the highest expected liquid without entering that dead band, considering foam and tank internals that affect echoes. A two-wire 4–20 mA version and an RS485/relay configuration differ in power and signal wiring. Remote probe cable and housing ingress ratings must match the environment.
