Stainless Steel Probe LMK 387H
level probe LMK387H

LMK 387 H

ceramic sensor
with HART®-communication

The stainless steel probe LMK 387H was developed for level and gauge measurement in wastewater, sludge or water courses. The mechanical robustness of the flush ceramic diaphragm facilitates an easy disassembly and cleaning of the probe in case of service.

The outer diameter is only 22 mm, whereby the installation or retrofitting can be easily carried out in 1 "pipes or in confined installation conditions. In addition to an intrinsically safe version (zone 0), a version with temperature signal is available.
