KELK List of Products and Services

The "KELGEN SD" is a thermoelectric EH wireless sensor device that operates on self-generated power simply by being placed on equipment that generates heat due to minor waste heat from piping or motors, and it wirelessly transmits sensing data. It is equipped with the high-performance, high-quality KELGEN thermoelectric power generation module and operates from a minimum temperature difference of 10°C (in still air). It has robust power generation performance against environmental changes. 【Product Lineup】 ■ Thermocouple Sensor Devices ・KSGD-STK-A00: K-type thermocouple, 0 to +1350°C ・KSGD-STB-A00: B-type thermocouple, +200 to +1800°C ・KSGD-STR-A00: R-type thermocouple, 0 to +1600°C ■ Analog Input Devices ・KSGD-SAC-A00: Current input type, 4-20mA ・KSGD-SAV-A00: Voltage input type, 1-5V *For more details, please download the PDF or feel free to contact us.

The "KELGEN SD/LT20-SSV" is a starter kit designed to evaluate the performance of the thermoelectric EH vibration sensor device and the communication network. In addition to one thermoelectric EH vibration sensor device, it includes equipment for a small-scale network (one master unit and three repeaters), as well as KELGEN SDM (data management software) and SD-Net signal strength verification software. This series allows for quick and easy setup from sensor installation to data collection, enabling straightforward evaluation and implementation of equipment monitoring with sensors. [Product Lineup] ■ With FFT: LT20-SSV2-A01 ■ Without FFT: LT20-SSV3-A00 *For more details, please download the PDF or feel free to contact us.

The "KELGEN SD/KSGD-SV" is a thermoelectric EH vibration sensor device equipped with the high-performance thermoelectric power generation module KELGEN. It operates from a minimum temperature difference of 10°C (in still air). By simply placing it on rotating equipment such as motors, it generates power from the equipment's waste heat, senses vibration and temperature, and transmits data wirelessly. 【Product Overview】 ■ Vibration acceleration sensor: ±16G 6kHz ■ Temperature sensor (vibration sensor section): -20°C to 80°C *For more details, please download the PDF or feel free to contact us.

The "KELGEN SD-Net" is a wireless communication network that connects data sensed by "KELGEN SD," which operates on energy harvesting. The standard network can connect up to 200 "KELGEN SD" units with one master unit, and by installing multiple repeaters, it can transmit sensing data over distances of more than 1 km. On the other hand, the small-scale network can connect about 20 to 30 "KELGEN SD" units and is a compact communication network that allows the sensed data to hop up to 5 stages via repeaters. 【Lineup】 ■ Small-scale network: For small start-ups ■ Standard network: Connects 200 units with one master unit *For more details, please download the PDF or feel free to contact us.
