WARNING: Do not exceed specified supply voltage
ratings. Permanent damage not covered by warranty
will result. This device is not designed for 120 or 240
volt AC operations. Use only on 10 to 28 VDC.
Optional Desiccant Filter (LD90‐3000):
o For extra protection against humidity we offer the LD90‐3000 desiccant filter that can be attached to
the vent tube.
Optional Cable Hanger (LD90‐S000):
o Attach the cable hanger to the ½” thread of the LD31 or LD32 series and
connect to the loop a chain to provide a secure method for lowering and
raising the sensor.
o The cable hanger is ideal for sumps or wet wells.
