How multi-sensor asset monitoring can improve performance in industry 4.0 factories and logistics and in datacenters
system designers can turn to the QM30VT2 sensor in an aluminum housing or the QM30VT2-SS-QP in a stainless steel housing, both from Banner Engineering. Both sensors can connect to a Modbus radio or any Modbus network as a slave device via RS-485. Their small form factor enables them to fit into tight locations (Figure 6). Other features include: ■ High-accuracy temperature and vibration measurements ■ Temperature measuring range of -40°C to +105°C, with a resolution of 1°C and an accuracy of ±3°C ■ Detects dual-axis vibration up to 4 kHz bandwidth with an accuracy
■ Outputs for rms velocity, rms high-frequency acceleration, peak velocity, and other parameters pre-processed from the vibrational waveforms Vibration spectral banding is an advanced capability. It allows users to split the wide band fast Fourier transformation (FFT) to get rms velocity or acceleration data for narrower frequency bands in addition to the 10 to 1,000 Hz and 1,000 to 4,000 Hz scalar data. Depending on users' needs, the band frequencies can be input manually or automatically generated based on a dynamic or static speed input. Spectral band analysis can aid in diagnosing problems with rotating machines more specifically.
Temperature and humidity Monitoring temperature and humidity can be important in data centers, warehouses, cleanrooms, refrigerators, or chillers. A temperature and humidity sensor like the DX80N9Q45THA can help to: Preserve goods like fresh produce or vaccines where knowing the temperature and humidity are essential to long-term viability and preventing spoilage Protect equipment like servers and storage devices in a data center where excessive temperature or humidity can interfere with normal operation or lead to breakdowns
of ±10% at 25°C and a default sampling frequency of 20 kHz
