BD Sensors LMK 458 pressure transmitter with stainless steel sensor Ø 39,5 mm

Description

Applications

Level measurement in sewage water tanks
Level measurement in sludge tanks
Level measurement in fuel and oil tanks
Level measurement in ballast and storage tanks
Drinking water abstraction desalinization plant
And many more customer-specific applications

Short description
The hydrostatic probe LMK 458 has been developed for measuring level in service and storage tanks and is certificated for shipbuilding and offshore applications.
A permissible operating temperature to 125 °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 LMK458 is a capacitive ceramic sensor element designed by BD|SENSORS, which offers a high overload resistance and medium compatibility.

Benefits

High overpressure capability
High long term stability
