HLC 370 Submersible Level Probe Features
Ceramic Hydrostatic Level Sensing
The capacitive ceramic sensor measures hydrostatic pressure to provide dependable liquid level monitoring in water, wastewater and industrial process media.Suitable For Viscous And Pasty Media
The robust diaphragm design is especially suitable for sewage, waste, viscous liquids and paste like products that may be difficult to measure with conventional level instruments.Wide Measuring Range Selection
The HLC 370 is available in level ranges from 0 to 0.4 mH₂O up to 0 to 200 mH₂O, supporting both shallow tanks and deeper liquid storage applications.Reliable Accuracy And Stability
Standard accuracy is ±0.35% of span, with an optional ±0.25% of span version available. Long term stability is specified at ≤ ±0.1% of span per year.Flexible Signal And Supply Options
The standard 4 to 20 mA two wire configuration operates from 9 to 32 VDC. A 0 to 10 V three wire output option is also available for compatible control systems.Durable Stainless Steel Construction
The wetted housing is manufactured from stainless steel 316L, with a ceramic diaphragm and POM nose cone for dependable use in submerged industrial environments.Adaptable Materials And Cable Choices
FKM, FFKM and EPDM seal options are available, along with PVC, PUR, FEP and TPE U cable options to suit the temperature range and media requirements of the installation.Hazardous Area And Mounting Options
Optional intrinsic safety certification supports use in designated hazardous areas. Flange mounting and R1 inch thread preparation for stainless steel pipe installation are also available.
