The Vibration Mote Model 3 (VM3) sensor combines speed detection with vibration and temperature, enabling continuous monitoring of variable speed assets. Variable speed, intermittently operating, and spared assets are difficult to monitor with predictive maintenance programs, says the company, since equipment operates under different conditions when measurements are taken, while with VM3, users can trend readings under consistent operating conditions.
VM3 offers sophisticated event-based measurement, such as taking readings only when the asset is operating or running at a specific speed. The smart measurements provide more consistent readings and allow for less frequent transmission and extended (five-year) battery life.
"VM3 is truly a step change in wireless sensors," says Kuldeep Amarnath, CTO at Petasense. "The smart measurement features are unique in the industry. We leverage edge computing to collect sensor readings at the perfect time, taking synchronous measurements and more comprehensive readings based on the condition of the prior reading. It allows you to monitor speed and operating state, taking readings only when assets are running."
Data from VM3 is transmitted over standard Wi-Fi to the ARO Cloud, where users can see at a glance what is happening with their assets and drill down for diagnostics with detailed analyst tools. VM3 also offers Bluetooth connectivity for greater deployment flexibility, providing a way for companies to get started without wireless infrastructure, using instant measurements with an iPhone or iPad.
Onboard storage minimizes data loss during connectivity interruptions. VM3 stores up to 50 high-resolution readings and transmits automatically when wireless connection is re-established.
Petasense CEO, Dan Bradley says, "Petasense is on a mission to eliminate unnecessary maintenance by simplifying the industrial internet of things. All digital plant initiatives start with good data. By adding speed detection and smart measurements, we help to address some of the key challenges and accelerate IIoT deployment."
