Keller Company High Precision/With Digital Output Submersible Level Sensor 26X
Achieves ±0.1% FS accuracy with RS485 output.
The high-precision water level gauge series 26X mathematically corrects temperature influences and non-linearity accurately on a microcontroller. There are types for absolute pressure or gauge pressure (using an open atmospheric pipe). In addition to the RS485 interface, measurement results can also be output as an analog signal via a built-in D/A converter, and scaling settings (range changes) can be made through digital signals. An option with built-in lightning protection devices is also available, allowing use in various harsh environments such as rivers, wells, and boreholes. It has excellent temperature characteristics due to digital correction of output errors caused by temperature changes. 【Features】 - Standard dual outputs of digital RS485 and analog output - Analog output can be range-changed via digital RS485 - Achieves excellent long-term stability - Maintenance-free 【Technology】 - Piezo-resistive pressure sensor - Correction technology using a mathematical model to produce accurate pressure values - Robust stainless steel housing
