Description

The LMK 458 has been developed for measuring level in service and storage tanks and is as a consequence certificated for shipbuilding and offshore applications.

A permissible operating temperature of up 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 LMK 458 is a capacitive ceramic sensor element designed by BD|SENSORS, which offers a high overload resistance and medium compatibility.

- nominal pressure: 0 ... 40 cmH2O up to 0 ... 200 mH2O
- accuracy: 0.1 % / 0.25 % / 0.35 % FSO
- diameter 39.5 mm
- high overpressure capability
- high long term stability
- permissible temperatures up to 125 °C

Optional Features:
- IS-version zone 0
