In addition to the critical role data loggers play in a data-acquisition system, there are other types of measurement devices. Some measurement devices are used to increase the number of terminals that data loggers can use, which enables them to measure more sensors or control more external devices.

			product Data LoggersData loggers are an essential component in data acquisition systems. They can scan a wide variety of measurement sensors, perform any programmed calculations, convert the data to other units of measurement, and store the data in memory. Data loggers can also transmit the data for analysis, sharing, and reporting, as well as control external devices.

			product External Data Storage DevicesExternal data storage devices can be used for redundant data storage, additional data storage, or convenient data retrieval from the field. These devices use a variety of technologies, including USB, flash memory, CompactFlash, and microSD. 
- 
			
		
			product Distributed Data AcquisitionDistributed Data Acquisition seamlessly networks all the components of your integrated monitoring system. The resulting synchronization decreases the quantity and lengths of communications wires between sensors and the data-acquisition system (DAQ). 
- 
			
		
			product Expansion PeripheralsExpansion peripherals are used with data loggers to achieve many purposes, including the following: add additional channels, extend data communications networks, perform media conversions, read vibrating wire sensors, and build distributed measurement networks. 
- 
			
		
			product Conversion Devices and AdaptersConversion devices and adapters fulfill several roles. For example, you can use them to convert an output signal to a signal type that can be measured by a data logger, to adjust resistive bridge measurements, or to build distributed measurement networks.
