SENSVISION HLC 360 – An Equivalent to the BD Sensors LMK 358
The BD Sensors LMK 358 is a detachable stainless steel submersible level probe with a capacitive ceramic sensing element. Suspended in the medium, it measures level hydrostatically from the pressure of the liquid column above the diaphragm, covering nominal ranges from 0 … 40 cmH₂O up to 0 … 100 mH₂O at a standard accuracy of ≤ ±0.35% FSO.
The SENSVISION HLC 360 is a directly equivalent detachable submersible probe covering the same 0.4 mH₂O to 100 mH₂O level range, corresponding to 0.04 bar to 10 bar, with the same ≤ ±0.35% of span standard accuracy and ≤ ±0.25% optional accuracy. It shares the ceramic measuring principle and output options, making it a straightforward replacement.
The defining feature of both probes is the detachable probe and cable assembly. The transmitter head separates from the suspension cable through a connector, so a damaged cable can be replaced, or a probe swapped for service or recalibration, without lifting and rebuilding the whole installation. In deep wet wells and sludge tanks this turns a major intervention into a routine one, and it lets a single spare cover several installations.
Like the LMK 358, the HLC 360 is specified for the difficult end of level measurement – wastewater, sewage, sludge and viscous or particle-laden liquids. The housing is stainless steel 1.4404 (316L) with a ceramic Al₂O₃ diaphragm in 96% or optional 99.9% purity, FKM or EPDM seals, and a suspension cable available in PVC, PUR, FEP and TPE-U to suit the medium and cable run. The probe is sealed to IP 68 for continuous immersion, with optional Ex ia versions for hazardous areas.
Whether you are replacing an installed BD Sensors LMK 358 or specifying a serviceable submersible probe for a new wastewater, biogas or industrial tank application, the SENSVISION HLC 360 delivers equivalent measurement performance and maintenance flexibility as a dependable, cost-effective alternative.
