The KELLER 26X level probe provides highly accurate measurement results and is characterised by its excellent long-term stability. By means of mathematical modelling, temperature dependencies and non-linearity are precisely compensated for by the microcontroller. The level probe can be operated with an analogue interface in addition to the RS485 interface. Thanks to the robust stainless-steel housing and a high-quality cable gland, the probe offers many years of maintenance-free operation. Extended lightning protection is available as an option. 

The 26X is typically used for hydrostatic pressure measurements, such as groundwater, surface water, water tank and fuel tank measurements.
