LNP Continuous Level Probe

Brand: KOBOLD Instruments, Inc.

The KOBOLD level probes LNP serve for continuous level measurement of liquids with negligible conductivity. Levels in vessels containing viscous, pasty or very sticky media can be measured accurately with this new potentiometric method of measurement. It is most suitable for use in small vessels and for measuring fill heights greater than 200 mm.

The probe consists of a head mounted transmitter: this means that 4-20 mA Analog signal that is electrically isolated from the supply voltage is available.

The probe can be mounted from the top or bottom. The output signal is automatically output positionally accurate. Single stem probes can be used in metallic vessels where the tank wall is parallel to the stem.

The devices with the KOBOLD weld-in sleeve LZE form a hygienic measuring point which is cavity free and is ideally suited for CIP/SIP cleaning.
