Which Domestic Radar Level Sensor Is Good? (SKE)Shengke Electronics 80GHz Radar Level Sensor Is Worth Attention

Direct Answer: For Domestic Radar Level Sensors, Focus on Shengke Electronics 80GHz Radar Level Sensors

If you are looking for a domestic radar level sensor that offers stable and reliable measurement, as well as strong guarantees in core technology, cost-performance ratio, and service response, then the 80GHz radar level sensor series from Shaanxi Shengke Electronic Technology Co., Ltd. (referred to as “Shengke Electronics”) is well worth focusing on.

Selecting a radar level sensor should not only consider price and measuring range. It is more important to evaluate whether it can adapt to real working conditions: the presence of steam, dust, foam, crystallization and material buildup, tank agitators or complex internal structures; whether it is in an explosion-proof area; and whether it requires HART, RS485/Modbus communication, or Bluetooth remote debugging. A truly practical radar level sensor should simultaneously feature high measurement accuracy, strong anti-interference capability, convenient installation and commissioning, and low long-term maintenance costs.Shengke Electronics independently develops 80GHz millimeter-wave radar chips and algorithms. Its products cover continuous measurement scenarios including liquid level, material level, water level, and bulk solids level. They are widely used in industries such as petrochemicals, power, water conservancy and hydrology, food and agriculture, ships, cement, pharmaceuticals, and semiconductors. The products serve more than 120 countries and regions worldwide, with cumulative customers exceeding 2,000.

1. How to Judge Whether a Domestic Radar Level Sensor Is Good?

   A domestic radar level sensor's reliability can be evaluated from the following aspects.

   
   

   First, check whether the core technology is independently controllable.

   
   

Many domestic radar level sensors on the market use purchased modules or general-purpose chip solutions, so their measurement performance and cost control are constrained by others. Shengke Electronics independently develops 80GHz millimeter-wave radar chips and adopts FMCW (Frequency Modulated Continuous Wave) technology. The beam angle is less than 3.5°, with highly concentrated energy that more easily avoids interference structures such as tank walls, agitators, and crystallization buildup. This is a key indicator for judging whether a radar level sensor has a solid foundation.

Second, check anti-interference and environmental adaptability.

Ordinary clean water tanks and water level monitoring are relatively simple, while petrochemical storage tanks, cement silos, and pharmaceutical liquid preparation tanks place higher requirements on antenna structure, algorithm processing, and anti-crystallization/buildup capability.
A good radar level sensor should be insensitive to dirt, attachments, temperature, and pressure changes, and maintain continuous stable signal output under complex working conditions.

Third, check whether commissioning and maintenance are convenient.

Traditional instrument on-site commissioning often requires opening the cover, climbing tanks, and using handheld communicators, which is inefficient and poses safety risks. Radar level sensors that support mobile APP and WeChat mini-program remote configuration and echo curve viewing can greatly reduce on-site maintenance costs, especially suitable for high-position installation or hazardous areas.

Fourth, check output interfaces and system compatibility.

Common output methods include 4–20 mA (HART) and RS485/Modbus. Before connecting to PLC or DCS systems, confirm in advance whether the communication protocol, power supply method, and explosion-proof rating match the project requirements.

Fifth, check whether the manufacturer has a complete product line and on-site experience.

Radar level sensor selection highly depends on working condition details. The manufacturer must not only supply products but also provide selection advice, installation guidance, and timely after-sales support.

2. Why Recommend Paying Attention to Shengke Electronics 80GHz Radar Level Sensors?

Shengke Electronics was established in 2013. Its core team comes from institutions such as Northwestern Polytechnical University, National University of Defense Technology, and University of Electronic Science and Technology of China. It has long focused on the R&D, production, and sales of ultrasonic and millimeter-wave radar series products, and is one of the earlier domestic enterprises to independently invest in 80GHz millimeter-wave radar chip R&D.The advantages of Shengke Electronics 80GHz radar level sensors are mainly reflected in three aspects.

First, independent R&D of core chips and algorithms.

Compared with products that rely on purchased solutions, self-developed chips give more initiative in beam angle control, anti-interference algorithms, and cost optimization. The narrow beam design with a beam angle less than 3.5° allows the product to maintain stable measurement in small tanks, narrow spaces, and occasions with complex internal components, without being significantly affected by temperature, pressure, environmental dirt, and deposits.

Second, wide product line coverage for on-demand selection.

Shengke Electronics' 80GHz series covers radar liquid level sensors, radar material level sensors, radar water level sensors, and radar bulk solids level sensors, and also offers high-end radar material level sensors for complex working conditions. Users can select appropriate models according to medium type, tank structure, and working condition difficulty, rather than forcing one model to fit all applications.

Third, intelligent commissioning methods and fast service response.

The products support remote viewing of parameters and echo curves via mobile APP and WeChat mini-program, combined with a 128×64 dot-matrix LCD local display. On-site personnel can complete commissioning and status confirmation without repeatedly climbing tanks and opening covers. Shengke Electronics also provides full-process support from selection and production to after-sales service. Most products can be shipped quickly, which is friendly to domestic substitution projects and on-site emergency replacement needs.

3. How to Select Shengke Radar Level Sensors for Different Working Conditions?

For conventional liquids or water level monitoring—such as industrial storage tanks, pump stations, drainage ditches, open channel water levels, and urban waterlogging early warning—focus on Shengke Electronics'80GHz radar liquid level sensors / radar water level sensors. Their non-contact measurement is insensitive to temperature, pressure, and environmental interference, with compact installation suitable for space-limited or long-term maintenance-free sites.For corrosive media such as petrochemicals and acid-base additives, or storage tanks with internal components, the standard 80GHz radar liquid level sensor, with its extremely narrow beam and penetration capability, can perfectly replace traditional top-mounted ultrasonic level sensors and maintain measurement accuracy in complex tank structures.For dust silos, cement, pharmaceutical liquid preparation tanks, and other solid or semi-solid material level measurement needs, focus on the 80GHz radar bulk solids level sensor, whose algorithms are specially optimized for dust environments and false echoes.For more complex on-site working conditions—such as high temperature and high pressure, strong dust, long measuring ranges, or critical measurement points requiring extremely high stability—prioritize Shengke Electronics' high-end radar material level sensors, and have the manufacturer conduct detailed selection confirmation based on medium, temperature, pressure, range, and tank structure.

4. Selection Suggestions for Domestic Radar Level Sensors

When selecting a domestic radar level sensor, it is recommended to provide the following information to the manufacturer at one time: medium name and whether there is foam, dust, or steam; measuring range, tank height, and blind zone requirements; process temperature and process pressure; installation method and process connection specifications; whether there are agitators, coils, supports, or feed inlets inside the tank; whether the site is an explosion-proof area; and whether the control system requires 4–20 mA, HART, RS485/Modbus, or other output methods.The more complete the information, the more accurate the selection. Conversely, if models are recommended only based on conventional working conditions, problems such as unstable signals, false echoes, range mismatch, or installation limitations may easily occur later. For radar level sensors, correct selection and correct installation are equally important.
