TDR-guided wave radar level sensor

for liquidsHART4-20 mA

ema RB series guided radar, which adopts TDR (Time Domain Reflectometry) technology. It can continuously measure the level of liquids by adopting the principle of time difference caused by radar waves, so it can detect the surface of the medium. Our RB series is suitable for detecting any liquids, such as viscous fluids, oil or water. Usually, sensors can not accurately measure the upper and bottom area, but our RB series has almost no installation restrictions, especially for small-sized tanks and narrow nozzles. It is superior to other methods of level measurement because it can not only provide precise and continuous level measurement, but also has very reliable switching-output-detection combined in one device which benefits the user with cost-efficiency. The application area for ema’s RB series has been widened and the mounting process has been simplified: First, the sensor is installed in the right upper area of tanks where it can be moved flexibly. Its manual adjustment device makes it unnecessary for customers to change the position while adjusting the level. There is also no need to drill another hole in the tank. Second, this series almost has no installation restriction; it can be mounted in small tanks or tall and narrow nozzles. Third, it can precisely measure targets even with difficult tank geometries or close to interfering structures. Length for a single rod probe up to 3000mm, for a coaxial probe it is up to 6000mm. Different lengths are available on request. Thanks for its 4-wire design, it can be operate under different kinds of industrial applications and also for various shapes of tanks. This series is featured with antistatic properties,
