Product of the Month

Fluke Corp., Everett, WA, introduced the Fluke 3560 FC Vibration Sensors and Fluke 3502 FC Gateway for equipment vibration analysis. The sensors enable remote capture of vibration data, and real-time alarms are sent through Fluke Connect Condition Monitoring software to a desktop or smartphone. The Gateway enables remote monitoring of equipment health when paired with Fluke Connect Cloud. The sensors enable measurement in tight or inaccessible locations, and identify potential equipment degradation or events by comparing sequential vibration measurements taken over time. Measurements can be saved directly from the tool and associated with a report or asset record. The sensors provide a range of 2 g, frequency range of 10 to 300 Hz, sampling rate of 800 Hz, and an operating temperature range from -10 to +68 °C. They are powered by 3.6-V, 2400 mAh lithium batteries, and are IP67 rated. The Gateway is powered by AC input and features a WiFi interface.
