Frequently Asked Questions About DAQs

The thermocouple or RTD type will depend on the temperature being measured, the required accuracy and other features. Because DAQs typically only support measurement with a limited number of thermocouple and RTD types, users often need to verify that the thermocouple or resistance thermometer being used is compatible with the DAQ before measurement.
KEYENCE’s NR Series DAQs allow users to perform measurement without having to worry about frequently checking the specifications. Nine different types of thermocouples and three types of resistance thermometers are supported.

Analyzing data collected by a conventional DAQ usually involves extracting the data from the main unit memory or recording media. With a KEYENCE NR Series DAQ, collected data is automatically saved to the PC and can also be automatically transferred to a server using the FTP client function.
The SNTP client function also synchronizes the time on the main unit with an SNTP server time for accurate data time management with no time adjustment needed.

As quality management standards become stricter, the need for measuring numerous channels is increasing.
Many systems use multiple DAQs to collect data from multiple channels, with the data being synchronized later in Excel.
KEYENCE’s NR Series of DAQs, however, can collect data from up to 576 channels with completely synchronized sampling.

With support for multiple inputs, the KEYENCE NR Series DAQ can collect various data from just a single device. This helps shorten data collection processing times and ensures the synchronization of data.
