Protective sleeves are a key component in the world of measurement technologies, especially in temperature sensors used in various industrial and construction applications. Andivi, a company known for its wide range of products for building automation and industry, offers a variety of protective sleeves that meet the specific needs of clients. On the product page for protective sleeves, you can find a detailed overview of these products. In this blog post, we will explore the different types of protective sleeves Andivi offers, customization options to meet individual requirements, and the most common industrial applications of these products.
Overview of the different types of protective sleeves in Andivi’s offer
Andivi offers protective sleeves designed for the installation of temperature sensors in pipe or duct systems, ensuring precise temperature measurement in various media, most commonly liquids. These sleeves come in multiple variants depending on the intended use and the conditions in which they are employed. The main types include sleeves for duct sensors, such as immersion duct sensors, and sleeves for cable sensors, for example, cable-mounted temperature sensors.
One of the key features of Andivi’s sleeves is their availability in different installation lengths. Standard lengths include 50, 100, 150, 200, 250, 300, 350, and 400 mm, but they can also be custom-made to meet the specific needs of a project. In addition to length, the sleeves also vary in the temperature range they can withstand. Basic models are suitable for temperatures up to +160°C, while special designs can withstand temperatures up to +400°C, and even up to +700°C, making them ideal for extreme conditions.
Pressure is another parameter by which the sleeves differ. Basic versions can withstand static pressures up to 16 bar, while more advanced models are designed for pressures up to 40 bar. Additionally, Andivi offers the option of installing a pressure screw, which enhances the safety and stability of the sensor during operation under high pressure. All these variants allow clients to choose a sleeve that best meets their specific requirements.
Customization options for protective sleeves
One of the biggest advantages of Andivi’s protective sleeves is the ability to customize them to meet the individual needs of customers. In addition to standard installation lengths, Andivi offers custom-made sleeves, which is especially useful for projects with non-standard dimensions or specific operating conditions. For example, if a project requires a sleeve longer than 400 mm or shorter than 50 mm, Andivi can tailor the product to meet these parameters.
The temperature range can also be customized. While standard sleeves can withstand temperatures up to +160°C, customers working in high-temperature environments, such as thermal power plants or the chemical industry, can request special versions that can endure temperatures up to +700°C. This flexibility ensures that the sleeves can operate in the most demanding conditions without performance loss.
Pressure is another area where customization is possible. If the standard 16-bar pressure is insufficient, Andivi can create sleeves that withstand up to 40 bar, with the optional installation of a pressure screw for added safety. This option is especially useful in systems with high pressures, such as hydraulic installations or steam systems.
The material of the sleeves can also be customized based on specific usage. While standard sleeves are made from stainless steel due to their corrosion resistance and long lifespan, Andivi can offer alternative materials depending on the medium in which the sensor will operate. For example, in aggressive chemical environments, a material with higher chemical resistance can be used. Additionally, for larger orders, an OEM version can be provided, where the sleeves can be branded with the customer’s logo or trademark, making it ideal for companies that integrate them into their products.

Most Common Industrial Applications of Protective Sleeves
Protective sleeves have a wide range of applications in industry, and Andivi’s products are designed to meet the needs of various sectors. One of the most common uses is in HVAC systems (heating, ventilation, and air conditioning). In these systems, sleeves are used to protect temperature sensors that measure the temperature of air or liquids in pipes and ducts. For example, immersion sleeves are often installed in pipelines to measure water temperature in heating or cooling systems, ensuring accurate data for optimizing energy efficiency.
In the chemical industry, protective sleeves are indispensable for measuring temperature in reactors, tanks, and piping systems where aggressive media or high pressures are present. Special designs for temperatures up to +700°C and pressures up to 40 bar enable safe and reliable process monitoring in extreme conditions, such as chemical production or oil refining.
The energy sector also frequently uses these products, especially in thermal plants and steam systems. Sleeves allow sensors to withstand high temperatures and pressures, which is crucial for monitoring the performance of turbines or boilers. In these applications, customized lengths and materials often play a key role in ensuring compatibility with existing infrastructure.
The manufacturing industry, including the food sector, uses protective sleeves for temperature control in processes such as pasteurization or cooling. Stainless steel as a material ensures hygienic conditions and corrosion resistance, which is particularly important in the food industry where standards are strict.
Finally, building automation is another area where Andivi sleeves are applied. In modern smart buildings, temperature sensors protected by sleeves are used to monitor and regulate the indoor climate, increasing user comfort and reducing energy consumption. Shorter sleeves for duct sensors are often used here, as they can be easily integrated into ventilation systems.
