A data acquisition system is a combination of hardware and software used to collect, digitize, and process measurements from real-world phenomena. In simplified terms, a DAQ system takes analog signals from sensors (for example, voltage from a thermocouple, strain gauge, pressure transducer, etc.) and converts them into digital data that a computer can store and analyze. The hardware typically includes sensors/transducers, signal conditioning (amplifiers, filters), and analog-to-digital converters (ADCs), as well as a communication interface to a PC. The software component provides the user interface and data logging, visualization, and often control or feedback functions. In essence, a DAQ system allows you to measure physical parameters like temperature, force, acceleration, electrical signals, etc., and acquire those readings into a computer for monitoring or analysis. For example, a DAQ setup might read a temperature sensor’s voltage, convert it to a digital value with a timestamp, and feed it into logging software that shows temperature vs. time. “DAQ” and “data acquisition” are broad terms – they can range from a simple USB data logger with one input channel up to very sophisticated high-speed systems with hundreds of channels. The core idea, however, is acquiring accurate, timely data from the physical world for further use.

Connecting a load cell (force sensor) to a DAQ involves a few key steps, since load cells are typically Wheatstone bridge devices:

1. Identify the load cell wires: Most load cells have four or six wires. A common four-wire load cell has +Excitation (often red), –Excitation (black or green), +Signal (white), –Signal (black or blue) – colors vary by manufacturer. If it’s a six-wire load cell, there are two additional sense wires for excitation feedback. Consult the load cell datasheet for the wiring code.
2. Connect to a suitable DAQ input or signal conditioner: The load cell’s bridge output is a small millivolt-level signal that usually requires amplification. Many data acquisition systems have dedicated strain gauge or bridge input modules. Connect the load cell’s excitation leads to the DAQ’s excitation supply outputs (the DAQ will provide a stable voltage, e.g., 5 V or 10 V, across the bridge). Then connect the signal leads from the load cell to the differential input of the DAQ module (signal+ to +Input, signal– to –Input). If the DAQ does not have a built-in excitation source, you’ll need a separate stable excitation supply. If it doesn’t have a suitable amplifier, use an external bridge amplifier or signal conditioner between the load cell and DAQ.
3. Provide power and turn on excitation: Once wired, the DAQ will drive the load cell with the excitation voltage. Ensure the excitation value is within the load cell’s specified range. The load cell will now output a small differential voltage proportional to the applied load (e.g., 2 mV/V means that at full load and 10 V excitation, the output is 20 mV).
4. Calibrate or configure the DAQ channel: In your DAQ software, configure that channel as a load cell/bridge input. Enter the load cell’s sensitivity (e.g., mV/V rating) and capacity. The system can then scale the voltage readings to engineering units (Newtons, kgf, etc.). Some systems allow a two-point calibration: you might record the output with no load and with a known calibration weight to fine-tune accuracy.
5. Verify the reading: With no load, the reading should be near zero (you may need to tare or zero it). Apply a known weight or force and verify the measurement matches. This confirms the wiring and scaling are correct. Load cells often require stable excitation and warm-up, so allow the system to stabilize if needed.

For example, connecting a 4-wire load cell: +Exc and –Exc go to the DAQ’s excitation supply terminals, and +Sig and –Sig go to the DAQ’s differential analog input. The DAQ module measures the voltage difference and, knowing the excitation voltage and calibration factor, outputs the force value. Always ensure shield/common connections are properly handled (connect the load cell shield to the DAQ ground if recommended) to minimize noise. After setup, you’ll have a continuous readout of force. In summary, you need to bridge the load cell to the DAQ, provide excitation, and configure the scaling so that the DAQ can output readings in physical units.
