A Universal Data Logger is a device or system that can record data from various sources across different channels. An 8-channel universal data logger, as the name suggests, can simultaneously log data from up to 8 different input sources.
Typically, the data logger can be configured to accept various types of input signals, such as analog voltage signals, thermocouples, RTDs (resistance temperature detectors), current signals, digital inputs (on/off), and more. The exact specifications and features of an 8-channel universal data logger may vary depending on the manufacturer and model.
Some common features you might find in an 8-channel universal data logger include:
1. Multi-channel input: As mentioned, it can handle up to 8 input channels to record data from multiple sources.
2. Data storage: It has onboard memory or storage capability to save the recorded data. This storage could be in the form of internal memory, SD card slots, or other external storage options.
3. Sampling rate: The data logger should allow you to configure the sampling rate at which it records data from each channel.
4. Communication interfaces: Most data loggers come with various communication options like USB, Ethernet, or RS-232/RS-485, allowing you to connect it to a computer or network for data retrieval and configuration.
5. Software compatibility: The data logger may come with proprietary software that allows you to configure the device, download data, and visualize it on a computer. Some data loggers might also be compatible with third-party data logging and analysis software.
6. Alarm and notification capabilities: Some data loggers have built-in alarms or the ability to send notifications if certain conditions are met or thresholds are exceeded.
7. Power options: Depending on the application, data loggers might support AC power, DC power, or battery operation.
8. Display: Some data loggers may have a built-in display that shows real-time readings or basic settings.
