Kayden News

Kayden Instruments manufactures an innovative line of Thermal Switches for use in flow, level and interface applications. We provide thermal flow switches, level switches and interface switches to many industries around the world. Our thermal products are operating in Oil and Gas, Water and Wastewater, and Chemical. Several companies who use our thermal switches can be found in the Customer Reference List section of our website.

Kayden switches are unique. Kayden switches use state-of-the-art microprocessor-controlled electronics. Highly accurate and reliable, Kayden switches include built-in diagnostics and Modbus communications capabilities. From simple on/off applications to complex control strategies, Kayden products provide solutions.

Kayden Instruments - Flow sensors & Level sensors Both our Classic and BASIC⁺ models can be used as either a flow switch, level switch or interface switch. There is no need to specify the switch function at time of order. The Classic or BASIC⁺ can be installed as a flow switch today and configured by the customer to be a level controller tomorrow. The Classic and BASIC⁺ models can be used in air, gases, liquids or slurries. With an array of sensor sizes, materials and configurations available including insertion and in-line, threaded or flanged and retractable packing gland styles, a Classic or BASIC⁺ model will fit your application.

The Kayden line of products is based on the thermal dispersion principle of operation. Though often referred to as a thermal dispersion flow switch, thermal flow switch, liquid flow switch or Modbus flow switch our products can also be used in level and interface applications. Some level applications are: level controller, tank level, high level alarm, low level alarm, wet/dry alarm and various other applications involving flow alarms. Another common application is interface control, especially those requiring an oil water interface switch. Kayden switches are also commonly used in pump protection, seal leak detection, and flow/no flow applications.
