From Data Acquisition to Fault Diagnosis: Nexisense Temperature & Vibration Transmitter Empowering Smart Factory Upgrades

In modern industrial production, stable equipment operation is the cornerstone of efficiency and safety. Temperature and vibration are two critical indicators that can reveal potential faults at an early stage, such as bearing wear or rotor imbalance. Traditional monitoring approaches are often fragmented and fail to provide comprehensive insights. By integrating innovative technologies, the Nexisense temperature and vibration transmitter combines multidimensional data acquisition and intelligent analysis, enabling factories to transition from reactive maintenance to predictive and intelligent operation. This article provides an in-depth analysis of the system and highlights its real-world value in modern factories.

System Definition and Importance

The Nexisense temperature and vibration transmitter is a composite sensor designed specifically for rotating machinery. It simultaneously collects temperature data and three-axis vibration data, including vibration velocity, displacement, acceleration peak values, kurtosis coefficients, and frequency spectrum information. More than a data acquisition device, it serves as a foundational component for fault diagnosis, helping identify equipment anomalies such as imbalance, looseness, and overheating.

In factory environments, such monitoring is essential. Failures in motors, fans, air compressors, and similar equipment often originate from abnormal vibration or rising temperature. Without timely intervention, these issues can lead to costly downtime. Traditional solutions rely on single-parameter monitoring and are prone to misjudgment. By fusing temperature and vibration parameters, the Nexisense transmitter provides cross-validation of data, significantly improving diagnostic accuracy, enabling predictive maintenance, and reducing unplanned downtime.

Nexisense Temperature & Vibration Transmitter Working Principle Analysis

The core of the transmitter adopts high-performance MEMS chips. Through micro-electromechanical systems, vibration signals are precisely captured. Built-in digital filtering algorithms effectively eliminate electromagnetic noise, ensuring stable operation even near variable-frequency drives or high-power motors. Vibration measurement is based on a three-axis accelerometer that calculates velocity and displacement in the X, Y, and Z directions. The temperature module uses surface-sensing elements to track thermal changes in real time.

Spectrum-analysis versions further process time-domain features such as RMS values and peak values, along with frequency spectrum data. By combining these with temperature thresholds, the system identifies fault patterns. For example, during early-stage bearing failure, vibration may increase slightly while temperature rises sharply by 8–12°C; the algorithm cross-validates these indicators to confirm the fault. Wireless versions integrate LoRa technology, enabling low-power data transmission to the monitoring platform with sampling intervals as short as two seconds. This working principle ensures data accuracy and avoids sensitivity drift caused by temperature variations.

Structural Design

The Nexisense temperature and vibration transmitter features a compact and durable structure. The enclosure offers a high protection rating, suitable for harsh environments such as coal mines and chemical plants. The core MEMS module integrates a three-axis vibration sensor and a temperature probe in a compact form, allowing easy installation on equipment surfaces.

Wireless models incorporate a LoRa communication module for long-distance data transmission, while wired versions use an RS485 interface. On the platform side, a cloud-based monitoring system stores historical data and supports weekly and monthly report generation. The modular design allows easy expansion, such as integrating water leakage or CO₂ sensors to form a comprehensive monitoring network.

Key Advantages

Compared with conventional devices that suffer from limited data dimensions, complex deployment, and fragmented analysis, the Nexisense transmitter stands out. Its multi-parameter fusion capability, combining three-axis vibration with temperature measurement, reduces false alarms caused by single-parameter reliance and improves diagnostic accuracy by more than 30%. The low-power design enables wireless LoRa transmission, eliminating extensive cabling and reducing maintenance frequency through long battery life.

Strong anti-interference performance is achieved through MEMS chip filtering algorithms, making the device suitable for high-interference industrial environments. The platform supports big-data analysis, visual reports, and electronic maps for hierarchical management. Compared with traditional piezoelectric sensors, it offers a smaller footprint, stable sensitivity, fewer false alarms, and significantly improved maintenance efficiency.

Nexisense Temperature & Vibration Transmitter Application Scenarios

The Nexisense temperature and vibration transmitter is widely used in industries such as coal mining, chemical processing, metallurgy, and power generation. In motor and gearbox monitoring, it captures imbalance vibrations and prevents bearing wear. In fans and generators, temperature data combined with vibration analysis helps diagnose misalignment and overheating.

In automated factories, wireless versions enable flexible multi-point deployment on equipment clusters such as air compressors and centrifugal machines, achieving plant-wide coverage. Platform-based alarms allow managers to respond promptly to equipment aging or component loosening. In large-scale projects, the transmitter integrates into industrial IoT systems, supporting remote inspection in high-noise or moving environments and enhancing overall operational safety.

Measurement Methods

The measurement process is highly automated and efficient. Sensors are mounted on equipment surfaces with proper alignment of the X, Y, and Z axes. Vibration velocity, displacement, acceleration, and temperature are collected in real time, with data updates every two seconds.

Spectrum analysis calculates kurtosis coefficients and peak-to-peak values. Platform algorithms process the data to generate fault diagnosis results. Wireless transmission simplifies installation, while cloud-based uploads support threshold settings such as vibration limit alarms highlighted in red. Users can customize alarm ranges, with notifications delivered via SMS, email, or voice alerts to ensure rapid response.

Installation Guidelines

Installation is flexible and straightforward. Sensors should be mounted at critical equipment points, such as near bearings, with secure surface fixation. Wireless models require only LoRa gateway configuration, while wired models connect to an RS485 bus.

After power-up, data output is verified and devices are bound to the platform using unique IDs. For multi-point deployments, consistent axial orientation and avoidance of strong interference sources ensure stable and reliable monitoring.

Maintenance and Care

Low maintenance requirements are a key advantage. Routine checks include verifying secure mounting and cleaning surface dust. The low-power design minimizes battery replacement frequency, and the platform continuously monitors device status with automatic alerts for anomalies.

During maintenance, avoid strong impacts or exposure to corrosive substances. Historical data analysis supports predictive maintenance planning, extending sensor lifespan and ensuring long-term operational reliability.
