KCF Technologies’ Thermal Energy Harvester (TH-1) eliminates the need to change batteries by harvesting electrical energy from the temperature differential between a surface and the surrounding air.
Why Use Thermal Harvesters?
Wireless sensors offer great promise for cost savings and downtime avoidance, but battery replacement can affect the value proposition in locations that are inaccessible or where batteries are precluded. KCF Technologies’ Thermal Energy Harvester (TH-1) provides a reliable solution for these cases. TH-1 eliminates the need to change batteries by harvesting electrical energy from the temperature differential between a surface and the surrounding air. The Thermal Energy Harvester uses a Bismuth Telluride (Bi2Te3) thermoelectric generator and a proprietary heat sink to tolerate harsh industrial environments and reliably harvest energy from temperature differentials as small as 15°F.

Harvester Power Generation
Thermal Harvester generates power based on the difference in temperature between the surface that the unit is mounted on and the ambient air temperature. The harvester will generate sufficient energy to power the SmartDiagnostics® sensor nodes with as little as a 15°F temperature gradient. The amount of energy harvested increases with larger temperature differences as shown in the chart below.
Federal Communications Commission Compliance ‒ FCC Class B Device Statement The radio equipment in the SmartDiagnostics Receiver Nodes and SmartDiagnostics Sensor Nodes has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. Hazardous Location Information ‒ The SmartDiagnostics Vibration Sensor Node model SD-VSN-2N is certified to be suitable for use in Class I, Division 2, Groups A,B,C,D or non-hazardous locations only.
