Fluke vibration sensors operate without batteries

Dec. 2, 2021
Sensors can harness heat or light to offer constant monitoring of non-vital assets.

3562 vibration sensor Fluke’s range of vibration sensors monitor the vibrations made by various kinds of industrial equipment and alert users when inspection of the equipment is warranted to head off costly downtime.

What’s new? Batteryless operation. The new 3562 vibration sensor depends on energy harvesters — either a thermoelectric generator (TEG) or photovoltaic (PV) harvester — or both. The TEG is placed on the warmest part of the machine, and generates current from a temperature differential between two sides of its bimetallic device. The PV harvester gets sufficient current from even dimly lit facilities to power the 3562, and in outdoor settings, gets more than enough energy to power it through daylight hours. The sensors and harvesters can be attached to an asset with magnets, screws, or epoxy.

Benefits “Set it and forget it” functionality. Non-vital, Tier II and Tier III assets can be economically monitored with these sensors, which provide continuous monitoring without the need for battery changes. A long-range sub-gigahertz radio signal allows signals to reach the sensors’ gateway over large distances within a facility. The gateway sends that data to Fluke’s Live-Asset Portal through Wi-Fi, Ethernet or LTE connection, and users can view the data and receive alerts via the Live-Asset Portal web app.
