Description
Precision in Solids: The OPTISWITCH 3300
The OPTISWITCH 3300 is a premier vibration level switch engineered for the rigorous demands of solid applications. Unlike its flexible-cable counterparts, this device features a robust tube extension, a design choice that enhances its durability and precision. It is the ideal instrument for detecting minimum or maximum levels of bulk solids and powders, even in the most challenging environments. The rigid extension makes it uniquely suited for applications where the sensor needs to reach through thick silo walls or where a specific and stable switching point is required. Its ability to operate reliably with materials of extremely low density, such as certain aerosols or lightweight powders, further solidifies its position as a versatile and indispensable tool for industrial level detection.
Robustness and Adaptability in Action
The key to the OPTISWITCH 3300’s performance lies in its unwavering robustness. The rigid tube extension provides a stable measuring point, preventing the sensor from being influenced by the movements or dynamics of the bulk material. This makes it an excellent choice for abrasive media that might cause damage to other sensor types. The device’s highly resilient and abrasion-resistant tuning fork ensures long-term reliability and accuracy. A standout feature is its maintenance-free operation, as it remains unaffected by changes in the measured product’s properties, such as humidity or particle size. This simple “set it and forget it” functionality significantly reduces operational costs and minimizes downtime, making it a highly efficient solution for continuous processes. The straightforward setup, which requires no product calibration, ensures quick and easy installation.
Exclusive Applications: Where The 3300 Shines
The OPTISWITCH 3300’s rigid design and high-temperature capabilities open the door to a host of specialized applications. In the cement and construction industry, it is perfectly suited for high-level detection in cement or aggregate silos, where the abrasive nature of the media demands a durable sensor. In the food and feed industry, it is used for level control of grains, flour, and animal feed pellets, where its hygienic connection options, like Tri-Clamp®, are essential. The device’s wide process temperature range, from -50°C to +250°C (-58°F to +482°F), makes it invaluable in chemical and pharmaceutical production, where extreme temperatures are common. Furthermore, its ability to detect solids in water provides a niche but critical function in mining and mineral processing for monitoring settled tailings in ponds or slurry tanks. The flexibility to adjust the switching point with its rigid extension makes it ideal for managing conical material piles.
Uncompromising Quality and Certified Safety
When you choose the OPTISWITCH 3300, you are choosing a product that meets the highest standards of quality and safety. The wetted parts are meticulously crafted from austenitic stainless steel (1.4404/316L), providing exceptional corrosion resistance and durability. This ensures the device’s longevity even in harsh chemical environments. The extensive list of certifications and approvals, including ATEX, EAC Ex, FM, and CSA, validates its suitability for use in hazardous (Ex) areas. Furthermore, its SIL 2 safety integrity level rating confirms its reliability in safety-critical applications, giving you complete confidence in its performance. With an ingress protection rating of IP66/67 and NEMA4/4X/6, the OPTISWITCH 3300 is built to withstand dusty, dirty, and wet conditions, ensuring uninterrupted operation.
