HLC 900 Detachable Plastic Submersible Level Probe For Aggressive Media

The SENSVISION HLC 900 is a 45 mm diameter plastic submersible level probe designed to measure hydrostatic pressure and provide continuous liquid level measurement in wastewater, water recycling systems and compatible acids and alkalis. Its semi flush ceramic diaphragm supports use in more viscous media, including sludge, by helping to reduce the effect of deposits at the measuring point. The PP HT housing, ceramic sensing element and selectable seal and cable materials provide a configurable solution for demanding submerged installations.

The probe features a detachable transmitter head and cable assembly, connected through an M12x1 four pin connector. This arrangement can simplify maintenance and stock management because the transmitter head can be changed without replacing the entire cable assembly. The HLC 900 is available with ranges from 0 to 0.4 mH₂O to 0 to 100 mH₂O, standard 4 to 20 mA two wire output and an optional 0 to 10 V three wire output. IP68 ingress protection, accuracy up to ±0.25% of span and optional cable protection further support reliable use in wastewater and aggressive media level measurement.

HLC 900 Plastic Submersible Level Probe Features

  1. Detachable Probe And Cable Assembly
    The transmitter head connects to the cable assembly using an M12x1 four pin connector. This allows the transmitter head to be changed more easily for maintenance and stock management purposes.

  2. Semi Flush Ceramic Diaphragm For Viscous Media
    The semi flush ceramic diaphragm is suitable for wastewater, sludge and other higher viscosity media where deposits can affect conventional pressure connections.

  3. Materials For Compatible Aggressive Liquids
    The PP HT housing, ceramic diaphragm and FKM or EPDM seal options allow the HLC 900 to be specified for many compatible acids, alkalis and aggressive process liquids.

  4. Wide Hydrostatic Level Range Selection
    Standard level ranges extend from 0 to 0.4 mH₂O up to 0 to 100 mH₂O, supporting shallow tanks, wells, treatment equipment and deeper liquid storage applications.

  5. Reliable Current Or Voltage Signal Options
    The standard 4 to 20 mA two wire output operates from 9 to 32 VDC. An optional 0 to 10 V three wire output is available with a 12.5 to 32 VDC supply.

  6. Stable Accuracy For Continuous Level Monitoring
    Standard accuracy is up to ±0.35% of span, with an optional accuracy of up to ±0.25% of span. Long term stability is up to ±0.1% of span per year.

  7. Submerged Construction With IP68 Protection
    IP68 ingress protection, a shielded cable with integrated atmospheric pressure reference tube and integrated lightning protection on the two wire version support dependable submerged operation.

  8. Flexible Cable And Installation Options
    PVC, PUR and FEP cable variants are available, together with optional cable protection through a PP HT pipe and accessories including assembly flanges and terminal clamps.

HLC 900 Applications For Wastewater And Aggressive Liquid Level Measurement

The HLC 900 is suitable for continuous hydrostatic level measurement where wastewater, sludge and compatible aggressive liquids demand a durable plastic probe with a semi flush ceramic diaphragm. Its detachable construction and flexible material options make it well suited to installations where maintenance access and media compatibility are important.

Suitable applications include:

  • Sewage treatment systems

  • Wastewater treatment plants

  • Water recycling facilities

  • Sludge tanks and sludge handling processes

  • Leachate collection and dumpsite monitoring

  • Industrial effluent tanks

  • Open process tanks

  • Acid storage vessels using compatible materials

  • Alkali storage vessels using compatible materials

  • Chemical process tanks

  • Contaminated water storage tanks

  • Industrial liquid level monitoring systems
