Achieves accuracy of ±0.05% / Digital correction / Range changeable / Digital + Analog dual output
The high-precision water level gauge series 36XW accurately mathematically compensates for temperature effects and non-linearity using a microcontroller, achieving an accuracy of ±0.05% FS. There are types available 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 can be made using the digital signal. 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 compensation for output errors caused by temperature changes. 【Features】 〇 High precision: ±0.05% FS 〇 Standard dual output of digital RS485 and analog 〇 Analog output can be range-changed via digital RS485 〇 Excellent long-term stability 〇 Maintenance-free for long periods 〇 Robust stainless steel housing ■ Gauge pressure: Measurement mode with atmospheric pressure set to zero at the time of measurement Comes with a sturdy cable that includes a vent tube to the atmosphere ■ Absolute pressure: Measurement mode with vacuum set to zero Water level is calculated as the difference between absolute pressure and atmospheric pressure using a separately prepared atmospheric pressure sensor.
