Tăng Minh Phát - Chuyên cung cấp các giải pháp đo mức chất rắn và chất lỏng

Cảm biến đo mức dạng Radar là thiết bị đo mức không tiếp xúc các chất lỏng và chất rắn chứa trong các bồn, Silo, bể chứa mà bằng mắt thường chúng ta ko thể giám sát được. Phương pháp đo mức liên tục bằng sóng Radar cho phép đo với độchính xác cao, thời gian đáp ứng nhanh, độ bề lâu dài và hoạt động mà không thương xuyên bảo trì hay bảo dưỡng.

Nguyên lý hoạt động cũng giống như cảm biến đo mức bằng sóng siêu âm tuy nhiên tốc độ xử lý nhanh hơn, triệt tiêu được các song ảo, độ chính xác cao hơn và tốc độ âm thanh sấp sỉ bằng 331m/s còn tốc độ radar là 300.000 km/s

1.1 Cảm biến đo mức chất rắn

Thông tin chi tiết: matsushima-m-tech.com

Measurement of powder level
Measurement range 0.3(from end of antenna)to 70.0m
Accuracy ±0.25% F.S.

The Radar Level Transmitter is designed specitically for medium/long range measurement of all kinds of power,particle and bulk solids.
The compact and high directional system with usage of higher frequency can reazlize the more stable level measurement.
Adjustments can be done by entering simple parameters.
The air purge function is normally integrated and there are many options such as angle adjustment for wider range of installation environments.

Radar is defined as an electronic system capable of locating objects not visible to the naked eye and determining distance, speed, shape and size, exploiting the propagation properties of radio waves.

Radar Level Transmitters are used for measuring liquids in general, powder or solid solids, paper mixtures, etc., on open or closed metal tanks with transparent measuring windows or on plastic containers.

Depending on the size of the tank, various antennas are proposed which are divided as follows:

A parabola: for products with low reflection and long distances

Cone: for products with good reflection and small distances

A stylus: like the cone ones, but they can be installed on smaller diameter nozzles

The angle of emission of the antenna is inversely proportional to the diameter of the antenna itself, and therefore the parabolic angle is particularly suitable for high reservoirs, having a more concentrated beam of emission of micro waves and therefore less sensitive to the internal lateral ...

3. Cảm biến đo mức dạng Radar hãng VEGA

In continuous non-contact level measurement with radar, the sensor sends microwave signals towards the medium from above. The surface of the medium reflects the signals back in the direction of the sensor. Using the received microwave signals, the sensor determines the distance to the product surface and calculates the level from it.

Liquids and solids are commonly measured with this measuring technique.

The advantages

  • Non-contact level measurement with radar is characterized by especially high measurement accuracy
  • Measurement is not affected by temperature, pressure or dust
  • User-friendly adjustment saves time

Non - Contacting Radar Level Gauge KRG-10 Now Comes,
Measurement Unlimited By the Imagination.


KRG-10 measures liquid level by transmitting low energy radar pulses toward liquid surface and receiving the radar echoes.
The travel time for the radar pulse is proportional to the distance between the gauge and the surface.
