LFDS68 — electrical switch versus proportional pressure

LFDS68 combines a digital pressure indication with switching/alarm and transmitter functionality. Commission the analog/digital pressure measurement separately from the adjustable switch thresholds, output contact rating, hysteresis and fault action. A setpoint alarm is not inherently an independently safety-rated shutdown switch. Verify process media, pressure range, panel voltage and selected LED/LCD variant from the actual LEFOO order code, without inferring hazardous-location approval.
