DAQ Device FAQs

What is a DAQ system?

DAQ stands for data acquisition. It is the process of collecting analog data like temperature and pressure from sensors, instruments and other devices and turning it into digital formats. This digitized data is then stored in a computer for faster analysis and reporting. 

A DAQ system allows real-time monitoring, data logging and analysis.  It is used in various fields such as scientific research, industrial automation, quality control and more. Combined with customized software and scripts- a DAQ system can be used as a powerful tool to improve and refine new designs ore test and automate with speed and precision. 

LabJack offers computer-based DAQ solutions. This means the LabJack is designed and most powerful when connected to a computer via USB, Ethernet or WiFi to configure, run software, and record measurements. 

Watch this video for a quick look at how it works.

What are the components of a DAQ system?

The DAQ system has four major components:

1. a DAQ device (the LabJack)that acts as the interface between your

2. computer and 3. external sensors or devices, and 4. DAQ software that can store, analyze and report the data.

How do I choose the right DAQ device for my application?

To choose a DAQ device that meets your specific performance specifications, determine your needs in terms of speed for capturing data or the level of detail in the measurements. Consider your voltage range and channel count, along with how many devices or sensors you need to connect one time.

For example, the LabJack T4 is best for engineering students or hobbyists who need an affordable and easy-to-use DAQ device for simple tests. The LabJack T7, typically used in laboratory or industrial settings, has higher analog input resolution (16 bit) for more precise measurements, and internal amplification for tiny signals like Thermocoules, Bridge Circuits and Load Cells. 

LabJack offers more than just the little red box that includes hardware, detailed datasheets, app notes, software and legendary customer support. Our engineers can recommend the right DAQ system for your application and goals.

Our engineers are available for live chat on Mondays to Fridays between 9 AM to 11AM and 2 PM to 4 PM Mountain Time. Click the chat bar at the bottom right of any page, or see our Contact page for other ways to get in touch with us.

Can I get additional features for my LabJack DAQ system?

Yes! You can enhance or expand the capabilities of your DAQ device with accessories, expansion boards or a DAQ module.  

For example, LabJack’s LJTick-DAC and LJTick-DIO modules provide additional analog output or digital input/output channels.  

The DAQ module integrates seamlessly with LabJack devices, offering plug-and-play functionality and compatibility with our software and programming libraries. 

What accessories do you offer?

LabJack has everything you need to set up your DAQ system. We provide cables, connectors, mounting hardware and other peripherals for installing, connecting or protecting your DAQ device.  

Our optional accessories include: 

• The CB15 is a simple screw terminal breakout for the DB15 connector. 
• The CB37 is a simple screw terminal breakout board for the DB37 connector. It only works with the U6 and T7 devices and can also be paired with the Mux80 for high channel application up to 84 AINs. 
• The Mux80 is an Analog Input Expansion board for the T7 and U6. It is connected directly to the DB37 connector and can allow a single device to read up to 84 AINs. 
• The RB12 Relay Board provides a convenient interface for the LabJack to industry standard relays to interface a LabJack with high voltages/currents. The RB12 relay board connects to the DB15 connector on the LabJack output or input.  
• The LJTick-Divider (LJTD) signal-conditioning module is designed to divide two single-ended higher voltage analog signals down to 0-2.5 volt signals. 
• The LJTick-DAC (LJTDAC) provides a pair of 14-bit analog outputs with a range of ±10 volts. It plugs into any digital I/O block. Up to 10 of these can be used per device to add 20 analog outputs. 
• The LJTick-InAmp (LJTIA) signal-conditioning module provides two instrumentation amplifiers ideal for low-level signals such as bridge circuits (e.g., strain gauges) and thermocouples. Each amplifier converts a differential input to single-ended. 
• The LJTick-RelayDriver (LJTRD) allows 2 digital I/O lines to each control a relay or other moderate load up to 50V/200mA. 
• The LJTick-CurrentShunt (LJTCS) signal-conditioning module is designed to convert a 4-20 mA current loop input signal into a 0.47-2.36 volt signal. 
• The LJTick-Proto (LJTP) consists of an 8x8 grid of holes for prototyping custom signal-conditioning modules.
