80GHz vs 26GHz radar level transmitter

In the field of industrial level measurement, radar level transmitters feature non-contact measurement, resistance to harsh environments and high stability. They have become the standard measuring instrument for tanks, silos, reactors and other equipment. Among them, 80G millimeter-wave radar level transmitters and 26G centimeter-wave radar level transmitters are the two most mainstream models on the market, widely used in chemical, power, metallurgy, food and many other industries. However, there are significant differences between the two in frequency characteristics, measurement performance and applicable scenarios. Improper model selection may lead to measurement errors, equipment failures and even potential production safety hazards.

 

I. Comparison of Core Parameters
 

Conclusion: The high-frequency characteristic of 80G radar delivers advantages for precision measurement, while the centimeter-wave characteristic of 26G radar focuses on long-range coverage and strong penetration.
 

II. Comparison of Technical Characteristics
 

80G Radar Level Transmitter: Precise Focusing for Complex & Fine Working Conditions
 

1. Concentrated signal energy with outstanding anti-interference performance
2. Ultra-high resolution for precision measurement
3. Flexible installation, adaptable to special scenarios
4. Advanced signal processing
    

Environmental Adaptability

• Advantageous Conditions: Working conditions with low dust, clean medium, limited installation space and complicated internal structures (with agitators). It can withstand temperatures from -40℃ to 1000℃ and pressures from -0.5MPa to 3MPa, suitable for measuring strongly corrosive, low-temperature, flammable and explosive media.
• Limitations: Signals are susceptible to interference in heavy dust and high-humidity environments, requiring a purging device. It performs worse than 26G radar for media with heavy foam and suspended solids.
  
  
   

26G Radar Level Transmitter: Stable & Durable for Severe & Rugged Working Conditions
 

1. Strong penetration capability and excellent resistance to harsh environments
2. Wide environmental adaptability: high temperature and high pressure resistance
3. Suitable for large-range measurement
4. Mature technology, high stability, and better anti-build-up performance than 80G radar
    

Environmental Adaptability
 

• Advantageous Conditions: Working conditions with heavy dust, high temperature & high pressure, strong corrosion, or media containing large amounts of foam / suspended solids. It has high tolerance to obstacles inside tanks and can stably capture echo signals even on severely fluctuating medium surfaces.
• Limitations: It struggles in narrow spaces (e.g. DN50 pipes) and high-precision measurement scenarios. Its low resolution fails to meet refined requirements such as trade metering and precision batching.
  
  

In summary, the 80G radar level transmitter acts as a precision instrument, focusing on high accuracy and anti-interference to satisfy refined production demands of modern industry. The 26G radar level transmitter is an all-round workhorse featuring stability, durability and cost-effectiveness for harsh and rugged industrial applications. When selecting models for industrial sites, comprehensive evaluation shall be carried out combining medium properties, vessel dimensions, environmental conditions, accuracy requirements and budget. Only by selecting the most appropriate model can accurate, stable and efficient level measurement be realized, guaranteeing production safety and operational efficiency.
