Verified manufacturer model evidence
The original LEFOO LFM52 technical page shows this exact instrument housing. Accuracy and analog/RS485 communication, display, power supply and pressure-range choice depend on the model ordering combination. This HVAC differential-pressure transmitter is designed for measurement in air or neutral gases.
LFM52 — Differential Pressure Transmitter
The regular LFM52 air differential transmitter lists variant pressure spans of ±100, ±1,000 or ±10,000 Pa and approximately ±1% full-scale accuracy. Check actual sensor zero, port reversal and acceptable common-mode pressure before using it for cleanroom or duct flow monitoring. RS485/Modbus and analog selections may differ by ordering suffix. Verify sensor zero, pressure connections and the selected output before installation.
LFM52 — conventional DP transmitter
LFM52’s approximate ±100/1,000/10,000 Pa options and ±1% FS family accuracy must be evaluated at the chosen measurement span. Port routing, field zeroing and tubing moisture protection matter for filter loading or cleanroom monitoring. Check selected analog output or RS485 map before wiring. Select the output, pressure range and wiring that match the actual HVAC application.
