INTRODUCTION
YHDAR-6x series adopts non-contact measuring method, the output (4-20) mA/RS485 signal, max measuring range is 70m. The antenna structure is further optimized, and the new microprocessor can perform higher-speed signal analysis and processing. The instrument can be used in more complicated working conditions such as reactors or solid silos.
WORKING PRINCIPLE
The antenna of YHDAR-6x launches a narrow pulse electromagnetic wave, and electro magnetic wave is reflected back when reach the medium surface and received by the same antenna. According to the two pulse interval, the microprocessor calculates the distance from the antenna to the surface of the measured medium, and convert it into material level signal.
FEATURE
YHDAR-6x series has small beam angles, and strong anti-interference ability, which improves measurement accuracy and reliability. The antenna size is smaller, easy to install. It has small measuring blind zone and shorter wavelength. HCDAR-6X has a good measurement effect for small tanks and small particles. Non-contact measurement, no YHDAR wear, no pollution. Output option: 2-wire (4-20 )mA HART and 4-wire RS485 Modbus.
