The system of Machine Health Monitoring represents a sensor-based device that converts vibration and temperature variations into measurable digital signals for predictive maintenance in industrial contexts.
TECHNICAL ANALYSIS OF THE SYSTEM
● The brand Machine Health Monitoring stands as a reference in the integration of vibration and temperature sensors with industrial connectivity.
● The device is defined by a triaxial accelerometer with ±64 g capacity, 16-bit resolution, and a maximum sampling frequency of 25.6 kHz.
● The measurement chain includes mechanical frequency responses of 8.2 kHz on the X axis, 8.5 kHz on the Y axis, and 5.6 kHz on the Z axis.
● Sampling sizes are configurable across 256 Hz, 512 Hz, 1024 Hz, 2048 Hz, 4096 Hz, and 8192 Hz, with 8192 samples per vibration point. 📊
● The device includes temperature sensing across a range of -40 °C to +70 °C and maintains environmental protection at IP67.
● The hub ensures communication through Wi-Fi 802.11 b/g/n at 2.4 GHz and 5.8 GHz, with WPA2-AES encryption. 🔐
● The hub and sensor are linked by Bluetooth Low Energy, with support for both manual readings and multiple daily acquisitions.
● Mechanical resilience is guaranteed by a drop test of 1 m and mounting options with nickel-plated base through magnet, epoxy, or threaded stud. ⚙️
● Physical dimensions reach 2.4 inches in height with 1.6 inches in diameter for the sensor and 1.2 inches × 3.3 inches × 3.3 inches for the hub.
● Weight is specified as 3.8 oz for the sensor and 3.2 oz for the hub, with a standardized ¼-28 UNF threaded connection. 📐
● The dashboard integrates time waveform visualization, Fast Fourier Transform analysis, and global velocity metrics across X, Y, and Z axes.
● Notification functions include SMS and email alerts with escalation structures and group allocation to reduce alarm fatigue. 📣
● Equipment mapping permits institutional nomenclature adaptation, enhancing identification within industrial inventories.
● The sensor and hub hold expected certifications under UN DOT 38.3, UL61010, Class I Division 2, ATEX Zone 2 (Directive 94/9/EC), FCC Part 15, CE, UKCA, and RoHS.
INSTITUTIONAL AND TERMINOLOGICAL FRAMEWORK
● The brand Machine Health Monitoring also denotes the institutional framework that positions the device in compliance with global directives and technical standards.
● The term “accelerometer” derives from Latin celer meaning swift and the suffix -meter from Greek metron meaning measure, denoting an instrument that quantifies acceleration.
● The term “sampling frequency” originates from the English root sample meaning a taken portion and the Latin frequentia indicating repeated occurrence, defining the rate of digital acquisition per second.
● The concept “Fast Fourier Transform” is named after Jean-Baptiste Joseph Fourier, with “transform” from Latin transformare, describing the conversion of a time-domain signal into a frequency-domain representation. 📚
● The technical designation “IP67” comes from International Protection with Ingress Protection as etymology, where “6” denotes full dust resistance and “7” indicates water immersion tolerance up to 1 m.
● The security protocol “WPA2-AES” combines “Wi-Fi Protected Access” with “Advanced Encryption Standard”, where encryptio from Latin means concealment, ensuring confidentiality in wireless communication. 🔒
● The directive “ATEX Zone 2” refers to ATmosphères EXplosibles, established under Directive 94/9/EC of the European Union, describing areas with rare occurrence of explosive atmospheres.
● The certification “Class I Division 2” is part of the National Electrical Code in the United States, designating hazardous locations with intermittent explosive gas presence. ⚠️
● The regulatory framework “FCC Part 15” originates from the Federal Communications Commission, with “part” derived from Latin pars meaning portion, specifying radio frequency device limits.
● The conformity marks “CE” and “UKCA” derive from French Conformité Européenne and English UK Conformity Assessed, affirming regional compliance with safety and electromagnetic compatibility.
● The environmental restriction “RoHS” stands for Restriction of Hazardous Substances, where substantia in Latin denotes material, prohibiting specific toxic elements in electronics. 🌱
● The mechanical connection “¼-28 UNF” identifies a unified national fine thread standard, where “thread” derives from Old English thraed meaning filament, denoting a helical fastening geometry.
● The notification term “escalation” comes from Latin scala meaning ladder, designating hierarchical progression in alarm routing.
● The concept “global velocity” in vibration analysis arises from Latin velocitas, expressing the root mean square velocity across the whole spectrum as a diagnostic index. 📈
