A Beginners Guide to Data Acquisition Terminology

From B&B Electronics Manufacturing Co. Inc.
 

 

Data Acquisition, or DAQ for short, is critical in today's manufacturing environment. DAQ Systems are designed to gather, store, and analyze data. With this information, plant managers can make intelligent decisions concerning process improvement, quality, and efficiency. This white paper examines some basic DAQ terms and concepts. It is intended as an introduction to the world of Industrial Data Acquisition and Control systems.

Products & Services
Data loggers and data recorders acquire digital data from sensors and other signals. They are primarily used to store data for subsequent downloads to a host PC, but may also include real-time features such as monitors and alarms.

Temperature signal conditioners accept outputs from temperature measurement devices such as resistance temperature detectors (RTDs), thermocouples, and thermistors. They then filter, amplify, and/or convert these outputs to digital signals, or to levels suitable for digitization. Search by Specification | Learn more about Temperature Signal Conditioners
Analog-to-digital converters (ADC) sample an analog signal and convert it to a series of digital values to represent the signal to a computer processor. Search by Specification | Learn more about Analog-to-Digital Converters
Digital-to-analog converters (DAC) transform a digital number into a corresponding analog voltage or current. Search by Specification | Learn more about Digital-to-Analog Converters
Sensor transmitters are measurement or signal conditioning packages that provide a standard, calibrated output from a sensor or transducer in the form of a current loop output (e.g., 4-20 mA). Search by Specification | Learn more about Sensor Transmitters
