Dhowa Technos and Japan Microsystems offer a battery-free, wireless vibration and temperature sensor with EnOcean radio. The device uses a solar cell as energy harvester, which means it doesn\u2019t require an external power supply. It regularly transmits the vibration and temperature data measured via EnOcean\u2019s wireless radio standard.<\/p>\n\n\n\n

Two probes with integrated vibration and temperature sensors can be connected to one vibration sensor, making it possible to measure vibration and temperature at two locations with a single unit.<\/p>\n\n\n

Rather than capturing the momentary value, the vibration sensor measures several hundred times within a certain time frame. These values provide information on total vibration, including positive\/negative peaks in both directions. They can be used, for example, to diagnose failures and age deterioration.<\/p>\n\n\n\n

Measuring vibration at predetermined intervals and enabling all-day measurement<\/h2>\n\n\n\n

The vibration sensor wakes up at specified intervals and continuously measures hundreds of acceleration points in one measurement. This means that the values of the three axes x\/y\/z are measured at the same time and two channels are measured sequentially in one measurement.<\/p>\n\n\n\n

The measurement result is sent via EnOcean radio and then the sensor sleeps until the next measurement. If the appropriate interval is set, continuous measurement (24 hours a day, 365 days a year) is possible even in places where lights are turned off at night, thanks to the power stored in the solar panel.<\/p>\n\n\n\n

Wireless, dust-proof and waterproof \u2013 making it easy to install in various environments<\/h2>\n\n\n\n

The main body provides IP65 protection, meaning it is dust-proof and drip-proof. The pickup part is sealed with silicone resin and is also dust-proof and waterproof. The sensor data is transmitted wirelessly via EnOcean radio. It\u2019s powered by a solar panel with an internal capacitor that stores energy. Sealing the device completely is no problem. Because of this setup, it can be positioned in a variety of environments.<\/p>\n\n\n\n
