Description

The LMK 458H 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 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 capacitive ceramic sensor element, which offers a high over-load resistance and medium compatibility.

Features:
- nominal pressure: 0 ... 60 cmH2O up to 0 ... 200 mH2O
