FluxDAQ+ Heat Flux Sensor and Thermocouple Measurement and Data Logging System

The FluxDAQ+ is a low-cost Arduino based data acquisition system that is designed to accurately measure the small analog DC voltage output signals from PHFS heat flux sensors, their integrated thermocouples and independent thermocouple based temperature sensors. The FluxDAQ+ enables precise measurement resolution at a fraction of the cost to other currently available systems.

Increased functionality has been added to the FluxDAQ+ to include data logging capabilities that are independent of a personal computer. New features allow the user to either take data directly to the computer and display real-time plots of heat flux and temperature (same as with the FluxDAQ) or run the device portably and log the data over time while connected to an AC outlet.  The data is recorded to an 8 Gigabyte SD memory card (included) which can be removed and accessed on a computer at a later time.

Everything offered with FluxDAQ.....
......but now offering long-term data logging
Key System Features

- 8 differential input channels for simultaneous measurements of both heat flux and temperature from 4 PHFS sensors.

- LCD screen for on-device measurement readout from one PHFS sensor channel.

- SD memory card for data logging while not connected to a computer.

- AC power adapter for powering the device while not connected to a computer.

- Free software for computer-based user interface and data recording through a USB cable connection.

- Automatic zeroing of current bias error for increased accuracy, especially while using high impedance sensors.

Applications

- Long-term studies of heat flux and temperature

- In-situ measurement of thermal insulation R-value using the PHFS-09 series sensors

- Building science studies - measure heat flux and temperature of entire building envelope over time
