Description
Overview
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).
- Immersion depth up to 100 m
- Available with various cable lengths
- Measuring ranges from 0.1 bar … 1 bar up to 0 bar … 25 bar
- Stainless steel membrane
- Hermetically sealed stainless-steel housing with PA protective cap
- Cable made from PUR, FEP cable is available as an option for aggressive media
- Optional temperature measurement with integrated Pt100 element
- Optional surge protection
