LFH Pressure Sensor

Brand: Sick AG

The LFH level probe is a rugged pressure transmitter for continuous level measurement. 

The liquid column above the probe creates a hydrostatic pressure which is a direct indicator for the liquid level. 

Through its permanently connecting cable, the LFH is submerged into the liquid. 

The precise measurement technology is integrated in a rugged stainless steel housing. 

To meet diverse requirements, the LFH level probe is available in two variants, standard and enhanced. 

For the enhanced variant there are a number of options available that extend the range of applications significantly. 

They include a maximum cable length of 250 m (standard design: 100 m), integrated temperature measurement, surge protection, and a connecting cable with highly resistant FEP sheathing (up to 100 m).
Features
  • Enables level measurement under difficult conditions where other measurement technologies fail
  • Rugged and reliable through robust mechanical design and high-grade materials
  • For cleaning purposes the probe can easily be taken out of the liquid
  • No drillings required in the wall of the vessel
