HKD901 Anti-Corrosion RS485 Water Liquid IP67 Radar Level Transmitter
There are two types of HBRD901 rod radar antennas: 100mm and 200mm. When the takeover is longer, it will not seriously affect the measurement and will increase some blind spots.
HKD901 Radar level
Resistance to slight condensation, suitable for corrosive environments with small flanges (minimum DN50) within 10m, small acid gas or steam in the tank
|HKD901 radar is not suitable when the temperature in the tank is high, sour gas or steam is large. The dead zone of HKD901 radar is generally less than 0.3m. It can only measure the environment of normal pressure, and can not add high temperature heat sink.|

Sichuan VACORDA Instruments Manufacturing Co., Ltd. is a professional production-manufacturing enterprise specialized in designing, producing and marketing of instruments and apparatuses. Our company has been established for 21 years since 1997 to grow up to be a team of high-quality, united, hard-working and truth-seeking characters. Solid foundation has been established.
According to different measurement principles, radar level gauges can be divided into two types. It is a radar level gauge that controls the liquid level, and its accuracy is generally about 10mm; the other is a radar level gauge, which is used for precise measurement and settlement, with an accuracy of 1mm. Structurally, it is divided into rod antenna, horn antenna and cable antenna, debugging, installing and using the analog signal output by the radar level gauge. The digital signal is superimposed on it by 4~20mADC to realize the compatibility of analog signal and digital signal, conforming to HART protocol. It can provide users with more attractive solutions, especially suitable for large fluctuations, condensation, suspension, viscous slurries, dirty media, and corrosive liquid level measurement. It has a continuous frequency self-calibration function to ensure stable measurement accuracy; it uses HART protocol for digital communication, and uses communication equipment or portable handheld devices to process liquid level variables; the output signal is an analog signal and a HART digital signal superimposed. Using the 4-20mAhar manual operator, the output signal can be divided into liquid level, calculated volume or standard volume; all configuration information and programs are stored in non-erasable memory. When the power is interrupted, all data can be restored; the frequency is continuously self-calibrated to ensure the accuracy of the level gauge.
