Advantages & Benefits
Advantages & Benefits
ADVANTAGES OF KAYDEN'S THERMAL FLOW, LEVEL & INTERFACE SWITCHES
Kayden's thermal dispersion flow, level, and interface switches and transmitters offer many distinct advantages that make them highly valuable for monitoring and controlling the flow or level of liquids, gases, and slurries in various industrial applications, making them highly effective and dependable for critical applications in industries such as chemical processing, oil and gas, water and wastewater management, and pharmaceuticals, where precise monitoring of flow or level is essential for operational safety and efficiency.
NO MOVING PARTS
Reliability & Simplicity
Thermal dispersion, or calorimetric, switches do not have any moving parts, which significantly reduces the potential for mechanical wear and tear. This absence of moving parts leads to increased durability and reliability, minimizing maintenance requirements and prolonging the lifespan of the device, while providing simpler design and operation, reducing the risk of operational failures and simplifying maintenance procedures.
VIRTUALLY NO PRESSURE LOSS
Flow Path Design
The design of thermal dispersion flow sensors ensures that they introduce very little resistance to the flow. This characteristic is crucial in applications where maintaining the existing pressure level is critical.
Minimal Intrusion & Obstruction
Thermal dispersion flow sensors, having no moving parts and providing minimal intrusion into the flow, ensures that they do not significantly disrupt the fluid's path or create turbulence, thereby causing minimal obstruction to the flow of the medium, and reducing the potential for pressure drops.
Energy Efficiency
By minimizing pressure loss, these sensors help maintain energy efficiency in the system, reducing the need for additional energy to compensate for pressure drops.
Ideal for Sensitive Systems
This feature makes them ideal for use in systems where pressure stability is crucial, such as in certain chemical processing or HVAC applications.
Kayden's Classic 800 Series of thermal dispersion flow switches and transmitters are particularly advantageous in applications where maintaining the original pressure of the system is crucial. Their design minimizes pressure drop, ensures high accuracy and reliability, and offers a versatile solution for a wide range of industrial applications. These benefits make them an excellent choice when pressure loss is a critical consideration.
EXAMPLE APPLICATIONS
Chemical Processing
Accurate flow measurement without pressure drop helps in precise mixing and reaction control.
Water and Wastewater Treatment
Ensures efficient flow measurement without adding to the system’s pressure load.
HIGH ACCURACY AND SENSITIVITY
Precision & Consistency
Thermal dispersion switches are known for their high accuracy in measuring flow or detecting fluid levels. They can detect low flows and small changes in the flow rate or level, making them suitable for applications requiring precise control. These devices provide consistent and repeatable measurements, which is critical for maintaining the efficiency and quality of industrial processes.
Direct Measurement
Kayden thermal flow sensors measure the flow based on the cooling effect of the fluid or gas on a heated sensor, providing accurate and direct flow rate measurements without significantly affecting the fluid dynamics.
WIDE RANGE OF MEDIA COMPATIBILITY
Versatility
Thermal dispersion switches can be used with a wide range of fluids, including corrosive and dirty media, further broadening their range of suitable applications. They are effective in both liquid and gas applications, which makes them versatile tools for diverse industrial environments.
Customization
Thermal dispersion switches can be customized with various materials and coatings to handle different types of fluids and operating conditions, enhancing their utility in specialized applications.
EASY INSTALLATION AND INTEGRATION
Flexibility
These switches are fairly compact and easy to install. They can be mounted in various orientations and configurations to suit different system designs. Kayden's thermal dispersion flow sensors are designed for easy insertion into the flow stream, allowing for straightforward installation without major modifications to the system. They can easily be integrated into most process control systems, offering outputs that are compatible with digital control systems, which facilitates easier monitoring and automation.
LOW MAINTENANCE
Cost-Effectiveness
The minimal maintenance requirements reduce ongoing operational costs. Since they are durable and very reliable, Kayden's thermal dispersion switches and transmitters decrease the need for frequent replacements or extensive and expensive system downtime for repairs. The no-moving parts' construction results in low maintenance requirements and reduced operational downtime.
Safety
Their robust design means fewer failures, which enhances the safety of the operations, especially in critical processes involving hazardous materials.
OPERATIONAL IN CHALLENGING CONDITIONS
Environmentally Robust
Thermal dispersion technology performs well in extreme environments, including high temperature and high pressure, as well as in hazardous areas where explosive gases or liquids are present.
Insensitive to Pressure and Temperature Changes
Unlike some other flow or level sensing technologies, thermal dispersion switches are less sensitive to variations in pressure and temperature, which can affect the accuracy and reliability of flow measurements in other sensor types.
NO CALIBRATION REQUIRED
Set and Forget
Once installed and configured, thermal dispersion switches generally do not require recalibration. They maintain their accuracy over time.
Consistent Performance
They offer stable and precise readings, which is essential for maintaining process control without introducing pressure variability.
Operating Principle
Operating Principle
Kayden's thermal switches are highly versatile and can be used in various applications, including cooling circuits, pump protection (to ensure there is flow in a system and prevent dry running), and process control in industries such as chemical manufacturing, pharmaceuticals, and food and beverage production.
