The high-precision level sensors of the 36XiW series measure with ultra-high accuracy and resolution. Temperature dependence and nonlinearity are precisely compensated for in the microprocessor by means of a mathematical model. They can be supplied with either an RS485 or SDI-12 interface. In addition to the pressure sensor for the level measurement, it is also possible to integrate a Pt1000 that is calibrated to ±0,1 °C from 0…50 °C. Extended lightning protection comes as standard with the SDI-12 interface and is available as an option for the RS485 interface.
