Sight glass for better process inspection

Today, high demands are placed on the technical capability and functionality of the modern process plant. In practice, it must be possible and safe to manage and monitor a process from A to Z. Sight glass, also known as inspection glass, is the answer and with it you can ensure whether gases, volume, temperature, color or process behave as desired from an outside view. At Alfotech you will find sight glasses for the process industry. They cover every need for inspection and monitoring of a process.

If you want more control over the flow of your media and to increase the reliability of your process equipment, you do not have to compromise on quality and design. At Alfotech, we supply the highest quality drawer glass for media flow, so you can keep your production equipment running without disrupting important processes.

Typically, sight glasses are used to inspect or monitor the flow of various media such as liquids and solids. Through the transparent glass it is possible to observe the medium without removing the contents from the container. In other words, you can potentially save several maintenance days by using sight glass, as the flow, color or presence of particles in the liquid etc. can be seen directly from the outside, while remaining safely inside a closed container.

There are also a variety of connection options, shapes and coupling sizes, so the drawer glass can be fitted to your needs. In addition, several sections can be put together to tailor the drawer glass solution to selected customer specifications.

Safety should undoubtedly be given high priority in the transport of foodstuffs and pharmaceuticals in the respective industries. Therefore, it is a vital part of the manufacture of drawer glass that the materials and construction are shatterproof in accordance with current legislation. In situations where glass is not permitted in the food and pharmaceutical industries, among others, we use shatterproof FEP. In addition to being shatterproof, our sight glass with protective net and FEP is suitable for transporting foodstuffs, as we comply with all European foodstuff requirements. In addition to being shatterproof and suitable for foodstuffs, our FEP tube and safety net sliding glass has the following properties:

• High chemical resistance
• Good antistick properties
• Non-flammable
• Extremely durable and UV-stable
• Low coefficient of friction
• Temperature coverage from -40°C to +150°C

There are several types of sight glasses that can withstand different temperatures, ranging from as low as -40°C all the way up to +280°C depending on the specific standard. For example, if you choose our DIN union sight glass, it covers temperatures up to +280°C with glass constructed from borosilicate for excellent strength and stability. Working at high pressure has an impact on the temperature resistance of the glass.

Whether you need sight glass that can withstand high temperatures, fit a specific standard or be chemically resistant, our knowledgeable sales consultants are ready to provide expert guidance.
