Level and Temperature Gauges

STAUFF level gauges and temperature indicators from the SNA, SNK and SNKK series are available in different versions and nominal sizes. They are suitable for combined optical and optical/electrical fill level monitoring and temperature measurement in hydraulic tanks with a maximum preload pressure of 2 bar.  

The standard versions are suitable for use with mineral oil-based and petroleum-based hydraulic fluids (HL and HLP). Alternative materials for improved resistance to UV and chemicals, for low temperatures down to -50 °C or for use with other media (e.g. bio oils, diesel, petrol) are available for these components (fluid level sight glass, housing, seals, screws) on request. 

The function principle of the components is either purely optical (SNA series) or optical/electrical with a switching contact (SNK series). The SNKK series features a particularly compact design.  

The elements are attached with corresponding attachment holes on the side wall of the hydraulic tank.
