Excellent radar level transmitter supplier
Radar level sensor manufacturer from China? What are the characteristics of radar water level meter? All measuring components are designed in an integrated manner, and there is no mechanical wear during measurement. Because the measurement is a non-contact measurement, it is not affected by the physical properties such as the density and concentration of the water body, it is not easy to be washed away by floods, has a long service life and is easy to maintain. The advantages of the radar level transmitter are obvious. The editor warmly reminds that to choose the right one, it is still necessary to meet your own situation.

Working principle: Working principle of radar level gauge: UHF electromagnetic waves are transmitted to the liquid level of the container under test through the cable or antenna. When the electromagnetic wave touches the liquid level and is reflected back, the instrument detects the time difference between the initial wave and the echo, thereby calculating the liquid level height. Select guided wave radar or airborne radar according to the dielectric constant and measurement length of the measured medium.
So what can be done about these difficulties? Under the condition of strong dust, on the one hand, the radar with high transmitting energy can be selected, on the other hand, the measurement software with continuous measurement algorithm of wave-loss waiting can be selected. When the radar encounters strong dust, it will not misjudge the measurement result even if the radar loses wave for a short time. After entering the state of continuous measurement algorithm, if the reflection wave of real material surface can be recognized within the set waiting time, the correct measurement value of material surface can be obtained. In the past, only a few foreign radars have this function. At present, there are also domestic radars with this function, and the practical application effect is very good.
Measurement accuracy, the accuracy of ordinary radar is generally ±10mm, and the accuracy of precision radar is ±3mm. Selection according to the actual needs of production. Range, according to actual needs, choose the antenna size. Note that the actual range is reduced in complex environments. Antenna type and antenna size, the larger the antenna size, the larger the measured range and the stronger the anti-interference ability. The antenna types of radar level gauge are rod type, bell mouth type, paraboloid and so on.
Humidity interference, when the humidity increases, it will cause the insulator resistance to decrease, the dielectric constant to increase, the skeleton to be fluffy, and the resistance to increase, resulting in an increase in leakage current and changes in capacitance and inductance. Also, it softens the colloid and reduces measurement accuracy. Chemical interference, chemical interference usually refers to some corrosive gases, such as acids and alkalis. The long-term action of these gases will not only damage the instrument and internal components, but also conduct electricity with the metal, affecting the normal operation of the radar level transmitter.

See extra details at kaidi86.com. The Magnetic Level Gauge all use vacuum tube technology, with a lifespan of 3-5 years, and protection grade is up to IP68, not easy to fade.
There is AC interference and the voltage is high. For example, for the radar level meter used in the production line, the power supply requirement is 24VDC (typical value), but in the on-site measurement, it is found that the power supply is displayed as 27.2V, which is significantly higher than 24VDC, resulting in a large measurement result and even a radar level meter. crash phenomenon. The installation position of the radar level meter is incorrect, which leads to deviations in the measurement. For example, the accumulation of aggregates in the transfer bin is a “mountain”-shaped cone, but only one radar level meter is installed near the discharge port of the return belt. , the installation position is too close to the discharge opening of the return belt, and at the same time, it is too far from the discharge opening of the feeding belt on both sides. Just below the radar level meter is the drop point of the return belt. If the distance is too close, the aggregate in the falling process will interfere with the radar level meter and form false reflections.
