HLS 310 Stainless Steel Level Probe Features
Compact 27 mm Probe Diameter
The slim 27 mm diameter housing supports installation in wells, boreholes and other space limited locations while maintaining robust stainless steel construction.Continuous Hydrostatic Level Measurement
The stainless steel sensing element measures hydrostatic pressure to provide a continuous output signal for level monitoring in water and compatible liquid applications.Wide Nominal Level Range Coverage
Nominal ranges extend from 0 to 1 mH₂O to 0 to 250 mH₂O, allowing selection for shallow water tanks through to deep wells and larger storage installations.Multiple Output Signal Options
The standard 4 to 20 mA two wire output is complemented by optional 0 to 20 mA, 0 to 10 V and 0 to 5 V three wire outputs for compatibility with a range of control systems.Reliable Accuracy And Long Term Stability
Standard accuracy is up to ±0.35% of span for nominal pressures of 0.4 bar and above, with an optional accuracy of up to ±0.25% of span. Long term stability is up to ±0.1% of span per year.Fast Response For Dynamic Level Changes
The two wire version provides a response time of 10 milliseconds or less, while the three wire version responds in 3 milliseconds or less, supporting responsive level monitoring.Durable Stainless Steel Wetted Parts
The stainless steel 1.4404 housing and stainless steel 1.4435 diaphragm, both equivalent to 316L, support reliable performance in water and compatible fuel storage applications.Hazardous Area And Safety Options
Optional intrinsic safety protection and a SIL version extend the HLS 310 to applications requiring hazardous area compliance or functional safety measures.
HLS 310 Applications For Water And Fuel Level Measurement
The HLS 310 is suited to continuous level measurement in water systems, filtered wastewater and fuel storage applications where a compact, robust stainless steel probe is needed.
