AquaWave 138 W51

The 138-W51 Radar Level Transmitter is a highly reliable and intuitive non-contact sensor designed for precise level measurement of both liquids and solids. Featuring advanced 80 GHz radar technology, it delivers consistent and accurate performance regardless of the material being measured or the surrounding environmental conditions. With a remarkable accuracy of ±5mm and an 8° beam angle, the 138-W51 operates efficiently across a temperature range of 0°C to 60°C. This two-wire transmitter provides a 4-20mA output with HART communication, ensuring seamless integration and reliable data transmission for your process control systems.
