LEFOO / Pressure Switches

LEFOO LFDS62 Digital Pressure Controller with Dry-Pump Protection is a distinct OEM controller/switch variant with its own electrical switching behaviour and pressure envelope. These engineering notes distinguish real buyer selection constraints beyond the manufacturer marketing overview.

Technical and order-code comparison

Device roleIntegrated ceramic-core pressure measurement, three-digit pressure/current display, AC load current monitoring, relay output and pump-protection functions
Range variants0–10 bar (ordering code 1) or 0–16 bar (code 2), ±1% full scale, 1.5× overpressure rating
Power and switching110–220 VAC; output is switched AC at supply voltage; maximum load 10 A — not an isolated 24VDC digital output
ProtectionDry-pump detection, motor overcurrent and rapid-cycling alarms are manufacturer-supported and may require setup
Environment−10…+50°C ambient, IP55; gauge pressure, G1/4 female default or NPT1/4
Original order exampleLFDS62-1-G (0–10 bar, G1/4); confirm wiring/control relay and supported pump current before purchase
Why choose itFor a mains-powered pump controller with configurable alarms. Do not replace with LFDS68 24VDC transmit/switch or a passive pressure sensor.

Application and electrical checks

Compare supply/output topology (mains AC switching versus dry relay), pump/motor starting current and the exact pressure span before ordering. Set upper/lower trip levels to avoid damaging short cycles. Select compatible process port, seal and medium; confirm the controller is never operated beyond its manufacturer proof limit.

LFDS62 — dry-pump protection and restart logic

LFDS62 combines electronic water-pressure control with dry-run protection. Commission the pump restart, low-pressure timeout and sensor fault behavior using its exact manual before installing it as a water-system safeguard. A displayed pressure value and programmable contact are not proof that an uncontrolled motor can be switched directly at any current. Compare load characteristics and power supply to the device relay rating, and test what occurs after mains restoration.
