In modern industrial production processes such as chemical, food, pharmaceutical, and environmental protection, enclosed tanks, reaction vessels, and storage tanks are enclosed spaces, and operators cannot intuitively grasp the internal medium status. Long strip plate type sight glass, also commonly known as rectangular clamp sight glass or frame type liquid level observation window, is a core accessory designed specifically for visual monitoring of enclosed equipment.
一、 Product Structure and Materials
The strip mirror adopts a split fastening structure as a whole, mainly composed of four parts: metal pressure plate, high temperature and pressure resistant glass window, sealing gasket, and high-strength fastening bolt.
The mainstream materials for the shell are carbon steel and stainless steel (304/316L): the carbon steel version has a high cost performance ratio and is suitable for conventional non corrosive working conditions; Stainless steel material is corrosion-resistant and suitable for food, medicine, and highly corrosive chemical media. The middle observation window is made of tempered borosilicate glass/high borosilicate glass, which is resistant to high temperature and pressure impact; Paired with PTFE, silicone and other sealing gaskets, it ensures long-term pressure resistance without leakage. It relies on multiple sets of bolts to evenly lock and fix, making disassembly and maintenance convenient. It supports customized non-standard sizes.
二、 Core functional advantages
Unlike circular small mirrors used for single point observation, the biggest highlight of a long strip mirror is the continuous rectangular visible area. A single window allows for a complete observation of the liquid level rise and fall, material flow status, liquid color changes, and the entire process of material mixing and reaction within a certain range. The screen is coherent and seamless, without the need for multiple small circular mirrors to be spliced together for observation, making data judgment more intuitive and accurate.
1. Real time visual monitoring: No need to open the tank, observe the medium liquid level, flow rate, foaming, sedimentation and other working conditions in a closed manner throughout the process;
2. Safe and controllable production: avoid the safety risks of medium leakage, high temperature burns, and material contamination caused by opening the cover;
3. Suitable for complex working conditions: able to withstand certain pressure and temperature, resistant to acid and alkali corrosion, and meet various production environments such as low temperature, high temperature, and hygiene level;
4. Flexible customization: The length, width, and material can be customized according to the customer's tank opening size, with strong universality.
三、 Widely applicable scenarios
The long strip plate mirror is widely used in various storage tanks, reaction vessels, fermentation tanks, heat exchange equipment, and mixing containers, covering many industries:
Chemical industry: reaction of reactor materials, monitoring of acid and alkali storage tank liquid levels;
Food and beverage, brewing industry: observation of hygienic liquid levels in fermentation tanks and blending tanks;
Medical and Biological: Internal Production Process Monitoring of Aseptic Tanks;
Environmentally friendly fluid production equipment for water treatment, petroleum energy, coatings and inks.
