HLC 360H Submersible Level Probe

HLC 360H level Sensor

The HLC 360H combines a capacitive ceramic sensing element with a robust stainless steel 316L housing to deliver stable and dependable hydrostatic level measurement. Its detachable construction allows the sensor section and cable assembly to be separated through a connector, simplifying maintenance and helping reduce downtime when replacement or servicing is required. The probe is designed for use in level measurement duties where durability, water ingress protection and consistent performance are essential.

With HART communication as standard, the HLC 360H enables configuration of offset, measuring span and electronic damping. It is available across nominal ranges from 0 to 0.6 mH₂O up to 0 to 100 mH₂O, with a standard 4 to 20 mA two wire output. The ceramic diaphragm is suitable for demanding wastewater and industrial liquids, while the IP68 protection rating, integrated lightning protection and optional intrinsically safe version support installation in a broad range of process environments.

HLC 360H Hydrostatic Level Probe Features

  1. Detachable Sensor And Cable Assembly
    The detachable probe design allows the transmitter head to be separated from the cable assembly through a connector. This supports easier replacement, servicing and stock management.

  2. Capacitive Ceramic Measuring Element
    A ceramic diaphragm provides reliable hydrostatic pressure measurement for liquid level applications, including wastewater, waste media and liquids with higher viscosity.

  3. HART Communication Capability
    HART communication supports adjustment of electronic damping, offset and measuring span when the appropriate interface, cable and software are used.

  4. Wide Level Measurement Capability
    Standard nominal ranges extend from 0 to 0.6 mH₂O through to 0 to 100 mH₂O. Customer specific ranges can be configured within the stated turndown capability.

  5. Strong Long Term Measurement Stability
    The probe provides long term stability of up to ±(0.1 × turndown)% of span per year under reference conditions.

  6. High Temperature And Environmental Resistance
    The HLC 360H is suitable for medium, electronics, ambient and storage temperatures from minus 20°C to 85°C, subject to the selected cable temperature rating.

  7. Robust Construction For Submerged Installation
    The stainless steel 316L housing, IP68 ingress protection and removable POM C protection cap support reliable use in submerged and exposed environments.

  8. Hazardous Area Option
    An intrinsically safe Ex ia version is available for use in specified gas and dust hazardous zones, subject to the applicable installation requirements and temperature limits.

HLC 360H Submersible Level Measurement Applications

The HLC 360H is suited to continuous liquid level measurement in demanding installations where the sensor may be exposed to wastewater, contaminated liquids, higher viscosity media or outdoor environmental conditions. Its ceramic sensing element, detachable assembly and HART configuration capability make it suitable for both new installations and maintenance focused replacement projects.

Suitable applications include:

  • Groundwater level measurement

  • Rain spillway basins

  • Wastewater treatment plants

  • Water recycling systems

  • Sewage handling processes

  • Open tanks with low filling heights

  • Fuel storage facilities

  • Tank farms

  • Biogas plants

  • Industrial water storage tanks

  • Process vessels containing compatible viscous liquids
