In the field of industrial automation, level measurement products such as level sensors and level transmitters play a crucial role. These devices not only need to be highly accurate and reliable, but also must be able to adapt to a variety of harsh operating environments.

As a result, IP Protection Rating (IPR) has become an important indicator to assess the reliability of these products in practical applications. In this article, we will analyze the IP protection rating of level measurement products to help industry players better understand this standard and its impact on product applications.

IP Protection Rating Overview

IP protection ratings are established by the International Electrotechnical Commission (IEC) to measure the ability of electrical equipment enclosures to protect against ingress of solid substances and liquids.The IP rating consists of two numbers, the first denoting the degree of protection against solids (e.g., dust, particles) and the second denoting the ability to protect against liquids (e.g., water). Ratings range from 0 (no protection) to 6 (full dust protection) and from 0 (no protection) to 9K (high pressure, high temperature water jet protection).

IP65: Dust and waterproof IP65 rated liquid level measurement products are completely protected against dust ingress and can withstand water flow from any direction. Devices with this rating are typically used in outdoor or semi-outdoor environments such as factory floors or open storage areas. In these environments, where equipment is often exposed to dust, moisture and even short periods of rain, the IP65 rating ensures proper operation and long life.

IP67: waterproof and dustproof IP67 rated equipment is capable of withstanding short periods of immersion in water (typically 1 meter depth for 30 minutes) and offers complete protection against dust. This type of equipment is suitable for environments where deep water immersion or frequent cleaning may be encountered, such as food processing plants or chemical factories. It maintains stable performance in more hostile environments, guaranteeing measurement accuracy and equipment durability.

IP68: Waterproof for long time IP68 rated level measurement products can be immersed in water for extended periods of time under specified conditions and are typically used in extreme humidity environments such as underwater detection or deep well measurement applications. This rating ensures that the device will not be affected by prolonged immersion and is widely used in special applications where waterproofing is required for extended periods of time.


IP69K: High pressure, high temperature and waterproof The IP69K rating means that the equipment can withstand the impact of high pressure, high temperature water jets and is typically used in demanding cleaning environments, such as equipment in food production lines. The ability of this type of equipment to withstand high-pressure water jets ensures that the equipment remains in stable working condition under high-pressure rinsing and prevents moisture or damage to internal components.

Impact of IP Protection Levels on Level Measurement Products 

Choosing the right IP protection class is critical to the long-term stability and reliability of liquid level measurement products. In practical applications, the correct IP rating can effectively prevent dust and liquid from infringing on the equipment, prolong the service life of the product and reduce maintenance costs. Therefore, when selecting level measurement products, you should choose the right IP rating according to the requirements of the actual working environment.

In addition, different IP ratings have different price and performance characteristics, and higher levels of protection usually mean higher costs. Protection levels, environmental conditions and budget need to be considered during the design and procurement phase to ensure the best return on investment!

reach a verdict

IP ratings play an important role in the selection and application of level measurement instruments products. Understanding the meaning of different IP ratings and applicable environments can help engineers and purchasers make more accurate choices to ensure the reliability and stability of the equipment in a variety of complex environments. In the industrial automation system, the reasonable selection of IP rating of level measurement products will directly affect the production efficiency and equipment maintenance costs.
