SENSING TOMORROW Submersible Level Transmitter Piezoresistive silicon pressure sensor Excellent repeatability and long term stability Cable with integrated air tube for atmospheric reference DESCRIPTION LMP633-NLN is designed for continuous level measurement in water and clean or waste uids. It is made by building in high stable and reliable stainless steel sensor and high accurate circuit board into the stainless steel housing.LMP633-NLN is completely sealed for submersion, yet vented through the cable to correct for barometric pressure changes. Nominal pressure: from 0~1mH2O to 0~200mH2O Output signal: 0.5~4.5VDC ( ratiometric output) Small thermal eect Excellent long term stability Ground water level measurement Water treatment plants Irrigation works Water recycling Level measurement in container Fuel storage Depth or level measurement in wells and open waters
