LMK 458H Hydrostatic Level Probe

The LMK 458H hydrostatic pressure level sensor is a fully certified sensor with ATEX Zone 0 and 20, Lloyds Register, DNV, CCS, and ABS approvals.

4-20mA and HART outputs with ability to rescale the range and made in 316L Stainless steel with submersible, thread or flange fittings make the LMK 458H ideal for tank level monitoring of a variety of liquids.

Able to be used offshore and certified for use in shipbuilding the LMK 458H provides accurate level monitoring in hazardous conditions. With a ceramic diaphragm allowing ease of cleaning and oil resistant cabling increasing its resistance against oil, gasoline, sea water and heavy oil, the LMK458H monitors levels in medium up to 85degC (185F).
