Korte, E. Sankey Document Published IoT HUB Product Guide v.1.0 Lasted Edited: 05/04/2020 4 | Page 1 Product Overview 1.1 Introduction The HUB is the central part of a product system that is designed to meet the following needs in the industries we serve: • Fill the gap where deploying KCF’s wireless vibration sensors is not feasible due to access, size, environment, etc. • Update the KCF’s General Input Nodes’ capability to ingest standard, 3 rd -party transducer data into SMARTdiagnostics ® • Extend our monitoring capability with the ability to collect data at the same time across multiple sensors • Extend our monitoring capability with the ability to “trigger” data collection so that we can collect data when it matters- when a machine is running or at specific times during a machine’s cycle 1.2 How It Works The HUB controls up to seven (7) sensors that are connected to the HUB with a cable. In this way, the HUB can both power the sensors and control how and when those sensors collect data. When data is collected, it is transferred from the sensor to the HUB over-the-wire. The HUB subsequently transmits that data wirelessly to a base station or repeater (using DARTwireless™) which then sends it to SMARTdiagnostics ® software for analysis. While the sensors can be installed on multiple or single assets, the ability of the HUB to coordinate/synchronize data collection across multiple sensors on a single asset allows for fully understanding of the asset’s overall health. 1.3 Applications The HUB was designed to address several unique challenges. A few of these are discussed here. KCF’s Wireless Vibration Sensor has a wide operating temperature range that…
