Kayden Instruments manufactures an innovative line of Thermal Switches for use in flow, level and interface applications. They provide thermal flow switches, level switches and interface switches to many industrial process customers worldwide. Our thermal products are operating in Oil and Gas, Water and Wastewater, and Chemical.

Kayden switches are unique using 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.

Both the 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 800 Series is the only thermal switch on the market that is capable of operating as a flow switch, level switch or interface switch while simultaneously offering temperature switch capability. The microprocessor design allows for easy setup via the Display Panel or remotely with Kayden's RCM software.

The CLASSIC 800 is Kayden's premier thermal dispersion series, suitable for use in Air, Gases, Water, Hydrocarbon-based Liquids and Slurries.

The CLASSIC 800 has several unique features which make it the world's most advanced Thermal Flow/Level Switch including: temperature mode, 4-20 mA outputs, Modbus, digital temperature compensation, automated self-test diagnostics, and a simple intuitive user interface.

For maximum versatility the CLASSIC 800 features "universal power", 12-24 VDC and 115-230 VAC, 50-60 Hz. With 4-20 mA current loop and two SPDT sealed relay contacts rated @ 5 amps and 230 VAC or 30 VDC max, these switches can be used in most applications. For maximum communications flexibility, Kayden offers these switches with Modbus via RS-485.

The BASIC+ 400 Series thermal switch is the most competitively priced offering in its category. With more advanced features standard than other similar switches, you get very good value with the BASIC+. The BASIC+ thermal switch can also be used as a flow switch, level switch or interface switch.

Features include: universal power input (12-24 VDC and 115-230 VAC), start-up bypass timer for pump start-up, adjustable heater power, and RS-485 remote communications providing for integration with centralized control systems. Each switch includes the free Kayden Remote Control and Monitoring (RCM) Software.

All switches feature CSA and FM approvals and CRN.

Designed solely to detect flow/no flow or wet/dry, this level or flow sensor is a good low cost alternative for non-hazardous applications. The CMP can be used as a flow switch or a level switch in liquids or gases (non-flammable).
