Unlocking the Power of DAQ Webinar Recap

/0 Comments/in /by

Interface hosted a technical seminar on the topic of data acquisition systems. With the demands for more data and faster processing with requirements to connect multiple devices in testing environments, there is an increasing need for high accuracy DAQ systems. Keith Skidmore and Dave Reardon detail the basics of DAQ, trends, products, software options and answer to questions in the webinar, Unlocking the Power of DAQ.

To start, a data acquisition (DAQ) system consists of hardware and software components designed to collect, process, and analyze data from various sources and convert it into digital format for further analysis and storage.

Components of DAQ Systems

  • Input:  Sensors (Ex: Force, Torque), Digital Signals (Ex: DIO, Counters), Timing Signals (Ex: IRIG, GPS) and Serial Streams (Ex: RS-232, RS-422)
  • Signal Conditioning Circuitry: Excitation, Amplifier, Voltage Offsets, and Filters
  • Analog-to-Digital Converters (ADC)
  • Digital-to-Analog Converters (DAC)
  • Hardware and Software for processing, analyzing, display and recording
  • Output Signal: prior to ADC, after DAC, or even after processing

Analog data acquisition systems acquire and process analog signals. Analog signals can include sensors that measure load, force, torque, strain, temperature, pressure, voltage, current, and many other physical or electrical qualities.  Digital data acquisition systems acquire and process digital signals. Digital signals can include on and off states, counters, serial streams, text data, video, GPS signals, and other advanced options.

 Key Considerations for DAQ Systems

  • Features
    • Supported range of inputs mV/V, VDC, mA, partial bridge, encoder, pulse, frequency
    • Included software and related functionality
  • Form factor
    • Bench top, rack mount, portable, ruggedized and others
  • Sample rate
  • Connectivity

Data Acquisition Systems 101

/0 Comments/in , /by

Engineers and testing professionals use data acquisition systems to enable smart decisions. The data retrieved through DAQ systems empower users to identify points of failure, optimize performance, and create efficiencies in products and processes.

When it comes to measuring force, the accuracy and reliability of the sensor is a critical component to receiving quality data. The data acquired from measurement devices, including load cells, torque transducers, and other types of force sensors, is valuable for product development, research, and robust testing to ensure performance and durability of all types of innovations. Ultimately, utilizing precision-based data provides enhanced control and response for all types of applications and use cases. Interface provides a wide range of data acquisition instrumentation that is easily paired with our force measurement products.

By definition, a data acquisition system is a collection of components used to acquire data via analog signals and converting them to digital form for storage, research, and analysis. Data acquisition systems, also called DAQ systems, typically are made up of sensors, signal conditioners, converters, plus computer hardware and software for logging and analysis. Interface experts are available to help pair the transducers with the right instrumentation.

The data acquired through the measurement device is only useful if it is logged for analysis and traceability. This is where instrumentation, in particular DAQ systems come into play, in not only transferring data, but also obtaining the right type of data in a format and data transfer method that works with existing user systems.

Data acquisition that utilizes analog output has long been the standard in the industry. As new requirements for use cases and applications grow, test and measurement professionals and engineers find these systems advantageous because of the lower cost, easy integration, and scalability. They also like the advantage of daisy-chaining multiple sensors together on a single cable run to maximize the amount of data through single tests. More data improves the quality of analysis and monitoring.

Advancements in sensor technologies coincide with growing demands for digitalization and to gather more testing data. This is seen using multi-axis sensors, along with requirements for multi-channel acquisition that can integrate into existing systems already designed with specific digital connections and protocols.

In addition to improving speed of data output, acquisition systems offer an abundance of value-added benefits. This is primarily due to the digital signal, as they are less susceptible to noise and are more secure. The systems also typically have built in error detection. Digital signals are best for transmitting signals across longer distances or when you need to allow for simultaneous multi-directional transmissions. Many people like the ease of integration, both into existing networks as well as with other testing devices.

Data acquisition systems and accessories come in many shapes and sizes, wired and wireless and there are also a handful of different software options in different systems. All these various products such as digital instruments, input and output modules, cables, monitors, and accessories. Interface offers a range of DAQ products, including full systems including the sensors.

TEDS 101

/0 Comments/in , /by

In the electronics industry, sensor compatibility challenges can lead to significant issues with efficiency, accuracy, safety and more. When it comes to force measurement sensors, incompatibility issues can railroad an entire project.  This is where the role of Transducer Electronic Data Sheets (TEDS) comes into play.

TEDS is a set of electronic data in a standardized format stored in a chip that is attached to a transducer, therefore allowing the transducer to identify and describe itself to the network and ease automatic system configuration. This self-identification capability for the transducer is needed for maintenance, diagnostics, and to determine mean time between failure characteristics. The chip stores information such as manufacturer name, identification number, type of device, serial number, as well as calibration data. The TEDS can be uploaded to the system upon power up or request. It also serves as documentation for the transducer.

Transducer Electronic Data Sheets (TEDS) provide:

  • Sensor with electronic identification
  • IEEE 1451.4 standard for smart transducer interface
  • Plug and play readiness
  • Storage of sensor information and calibration data
  • Use with new or existing sensors

IEEE1451.4 specifies a table of identifying parameters that are stored in the load cell in the form of a TEDS. TEDS is a table of parameters that identify the transducer and is held in the transducer on a EEPROM for interrogation by external electronics.

A TEDS chip becomes the ultimate tool to allow users to take off-the-shelf sensor solutions and integrate them into a total force measurement solution. The key benefits TEDS provide includes:

  • Eliminating potential for data entry error
  • Simplifying new system setup and speeds up the process
  • Making swapping load cells in and out of a test system seamless
  • Improving safety by ensuring the system has the correct sensors
  • Easily identifying and tagging sensor locations
  • Improving inventory control of sensors
  • Changing sensors out without jeopardizing integrity of the system

TEDS chips can be sold separately or integrated into existing systems such as instrumentation products. Interface offers both options, selling TEDS as a standalone accessory, as well as integrating them into instrumentation solutions, such as:

9840 Calibration Grade Multi-Channel Load Cell Indicator

Model 9840 is suitable for use in calibration labs, field service, or anywhere high accuracy is important.
