National Instruments 786575-01

The National Instruments 786575-01 Wireless Vibration Measurement Device, also known as the MON-10467, is designed for advanced vibration monitoring applications. This robust device features twelve input channels, powered by four delta-sigma analog-to-digital converters (ADCs) with analog pre-filtering, providing a high resolution of 24 bits. The sampling rate is configurable, with a notable example at a decimation rate of 32 achieving a data rate of 25.6 kS/s for a 10.24 kHz passband. The internal master timebase operates at a frequency of 13.1072 MHz with an accuracy of ±100 ppm, allowing precise measurements. Users can select input coupling between AC or DC through software, accommodating voltages of ±30 V for both input types and a common-mode voltage range of ±0.6 V. The wireless acquisition system supports a maximum per-channel record length of five seconds at 25.6 kS/s and ten seconds at ≤12.8 kS/s. Leveraging Bluetooth Low Energy (BLE) technology, the device operates within a frequency range of 2.400 GHz to 2.4835 GHz, with a maximum RF output power of 18 dBm for transmitting and a receiver capable of handling up to -5 dBm input power. The device's power requirements include a DC input of 24 VDC (max 6 W) with an operational range of 19 VDC to 30 VDC, and for AC, 100 V to 240 V AC at 50/60 Hz, with an operational range of 85 V to 264 V AC. It is compatible with InsightCM application software version 3.4 or later. The physical dimensions of the device are 11.61 in. × 12.32 in. × 4.37 in. without the antenna and 11.61 in. × 16.09 in. × 4.37 in. with the antenna attached, making it suitable for various industrial environments.
