The KELLER 232645.0246 level probe from the 26X series is a piezoresistive pressure transmitter for precise hydrostatic level measurement, designed for a pressure range of 0 to 10 mH₂O. An integrated microcontroller mathematically compensates for temperature-related variations and nonlinearity, enabling an accuracy of 0.1% FS at room temperature and a total error band of only 0.25% FS for both analog and digital outputs. In addition to the 4...20 mA analog output, an RS485 interface is available for digital evaluation; the probe is powered by 8...32 VDC. With an IP68 protection rating and a 15 m connection cable, it is suitable for continuous use in wells, tanks, level gauges, and shafts at compensated temperatures ranging from 0 to 50 °C. Calibration certificate included.
The 26X series is available in numerous other pressure ranges (relative and absolute pressure from 0–0.1 to 0–25 bar) as well as with different cable lengths and output signals. Other variants are available upon request.
