APPLICATION

The LD33 general purpose anti-corrosion submersible pressure level transmitter provides continuous liquid level measurement up to 34.65’ (10.5m) of water column with a 4-20 mA signal output. Constructed of corrosion-resistant PTFE, the sensor is offered in three level measurement ranges. Select the appropriate model based on your tank height. For convenient installation with junction box termination, package your level sensor with the PVDF pressure sensor mounting kit. Each kit includes a junction box with terminal strip, mounting plug and liquid tight cable connector. The LD33 pressure level sensor is well suited for clean liquids compatible with PTFE and FEP such as acidic and caustic chemicals.

FEATURES

  • Corrosion-resistant PTFE sensor body and FEP cable
  • Rugged sensor designed for complete submergibility
  • Maintenance-free vent tube with filter ensures accuracy
  • Mounting kit for easy tank install and conduit termination
  • Integral surge protection for lightning strikes or power surges
  • Automatic temperature compensation for reliable measurement
