Level Sensor

LMK 458 H

BD Sensors LMK 458 H Probe with Hart & Ceramic Sensor, from 0 … 60 cmH2O up to 0 … 200 mH2O, 39.5 mm Diameter

SKU: LMK 458 H Category:

The hydrostatic probe LMK 458H has been developed for measuring level in service and storage tanks and is certificated for shipbuilding and offshore applications. A permissible operating temperature up to 85°C and the possibility to use the device in intrinsic safe areas enable to measure the pressure of various fluids under extreme conditions. The basis for the LMK 458H is a self-developed capacitive ceramic sensor element, which offers a high overload resistance and medium compatibility.
