Kayden CLASSIC 810 Thermal Flow, Level, Interface Switch & Transmitter

Brand: Kayden Instruments
The Kayden CLASSIC 810 Flow, Level, Interface Switch & Transmitter features a precision-welded, highly accurate stainless steel sensor. Alarms and trip-points are field-configurable for flow, temperature, high or low, hysteresis, time delay, and more.

Ideal for liquids, gases, and slurries in a clean or dirty process, the CLASSIC 810 is available in a wide range of thread sizes and insertion lengths. Kayden's electronic thermal dispersion flow and level switches have no moving parts to foul, clog, or stick, resulting in exceptional reliability and requiring little to no maintenance.

With no moving parts and minimal invasiveness, Kayden's thermal flow and level switches provide a highly repeatable, accurate, low cost of ownership, long life, and easy-to-install solution for demanding air, gas, liquid, and slurry applications.

All Kayden® CLASSIC® models feature a rugged flameproof enclosure with blind or glass lens covers. Kayden’s advanced digital electronics will streamline the way you monitor and control your process.

    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.

    Operating Principle

    Kayden's CLASSIC 800 Series thermal flow, level, and interface switches and transmitters detect and monitor the flow rate or level/interface of a liquid or gas in a system based on the principle of thermal dispersion or thermal differential.

    The CLASSIC 800 Series operates by measuring the amount of heat carried away by the process media as it moves past a heated temperature sensor, compared to a reference sensor that measures the ambient temperature of the process media. The difference in temperature between these two sensors is used to determine the flow rate, interface, or point-level condition.
    Kayden calorimetric flow and level switches, also referred to as thermal flow monitors or level monitors function as follows:

    Heating Element
    The thermal switch has a heating element (or sensor) that is warmed to a certain temperature above the process media's temperature.

    Temperature Sensors 
    Alongside the heating element, the device includes temperature sensors. One sensor measures the temperature of the heated element, while another measures the ambient temperature of the process media.

    Flow Detection 
    When there is no flow or the flow is below a certain threshold, the temperature differential between the heated sensor and the ambient process media is more significant. As the flow rate increases, the process media carries away more heat from the heated sensor, reducing the temperature difference between the heated element and the reference element.

    Level Detection 
    If the level of the process media rises and comes into contact with the heated probe, the probe cools down due to the increased heat dissipation caused by the cooler process media. Conversely, if the level drops and the probe is exposed to air, the probe's temperature rises because air's thermal conductivity is lower, and it dissipates less heat.

    Signal Output 
    The switch translates the temperature difference into an electrical signal that can trigger an alarm, activate a relay, or send a signal to a control system, indicating whether the flow rate is above or below a preset threshold.

    Thermal flow and level switches are known for their simplicity, reliability, and the ability to work without moving parts, which minimizes maintenance and the risk of mechanical failure.

    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.

    Thermal level switches can be used for level detection in a wide range of applications, including overfill protection, and ensuring proper filling or emptying of tanks and containers. These monitors are suitable for use with various materials, including liquids and slurries, and can operate in challenging conditions, such as high pressure and temperature environments.

    Kayden's thermal dispersion flow, level, and interface sensing technology provides accurate results to achieve highly reliable and repeatable setpoint detection in a wide range of demanding applications, all while providing a long service life.
