HLC 400H HART Hydrostatic Probe Benefits
HART Enabled Level Configuration
HART communication allows adjustment of electronic damping, measuring offset and span to support efficient setup and optimisation for the installed tank or vessel.Ceramic Sensor For Reliable Hydrostatic Measurement
The capacitive ceramic measuring element delivers stable pressure based level measurement and offers strong resistance to overload in demanding liquid applications.Marine And Offshore Approval Support
The HLC 400H is designed for shipbuilding and offshore applications, with shipping approvals available from Lloyd’s Register, DNV, China Classification Society and American Bureau of Shipping.Wide Level Measurement Range
Standard ranges extend from 0 to 0.6 mH₂O up to 0 to 200 mH₂O, allowing the probe to be matched to shallow tanks, deep storage tanks and marine ballast systems.High Accuracy And Long Term Stability
For nominal pressures from 0.6 bar, the probe achieves accuracy up to ±0.1% of span at turndown ratios up to 5:1. Long term stability is specified at up to ±(0.1 × turndown)% of span per year under reference conditions.Seawater Resistant Housing Option
Stainless steel 316L is supplied as the standard housing material, while CuNi10Fe1Mn is available for improved resistance to seawater exposure.Robust Submerged Installation Design
IP68 protection, a shielded TPE U cable with an integrated atmospheric reference tube and a POM protection cap provide dependable performance in submerged installations.Hazardous Area And Mounting Flexibility
An intrinsic safety version is available for specified gas and dust hazardous areas. Submersible, screw in, flange and stainless steel pipe mounting arrangements can be selected to suit the installation.
HLC 400H Applications For Offshore And Marine Tank Monitoring
The HLC 400H is suited to continuous level measurement in marine and offshore environments where equipment must withstand demanding service conditions, seawater exposure and submerged installation. HART configuration capability, ceramic sensor technology and marine approval support make it a strong choice for vessel, offshore platform and water management applications.
Suitable applications include:
Ballast tank level measurement
Marine service tank monitoring
Ship draught monitoring
Offshore storage tanks
Vessel water tanks
Seawater handling systems
Desalination plants
Drinking water abstraction systems
Freshwater storage tanks
Industrial liquid storage vessels
Tank farm level monitoring
Hazardous area liquid level installations
