NI SCXI-1125 Data Acquisition Module

NI SCXI-1125 Data Acquisition Module

Main characteristics
Number of channels: It has 8 channels and can simultaneously collect data from multiple signal sources, making it suitable for application scenarios that require simultaneous measurement of multiple physical quantities.
Input types: Supports multiple input types, including strain gauges, thermocouples, DC voltage, etc. This versatility enables it to be used in conjunction with various types of sensors to meet different measurement requirements.
High-precision measurement: Capable of providing high-precision measurement results. For example, for strain gauge measurement, its accuracy can reach within ±0.1% of the full scale. For thermocouple measurement, temperature changes can be accurately measured, with an accuracy usually around ±1℃, depending on the type of thermocouple and the measurement range.
Signal conditioning function: Each channel integrates a signal conditioning circuit, including amplifiers, filters, etc. The amplifier can amplify the input signal, and the gain can be adjusted through software programming to adapt to sensors of different sensitivities. Filters are used to remove noise and interference from signals, improve signal quality, and parameters such as cut-off frequency can be set according to actual applications.

Application field
