DracalView
DracalView is a free software from Dracal Technologies for logging, adjusting an visualizing data from our USB sensors. It features an easy-to-use graphical user interface that supports all of our sensors communicating via the USB protocol. The built-in graphical module provides a quick and easy way to view data in real time. It also saves data in text files (configurable format) for importing into a spreadsheet or graphics software for later analysis.
- Works under Windows (Win7/8/10/11 64&32-bit), Mac OS X and Linux
- Easy-to-use calibration mechanism open to the end-user
- Supports the simultaneous use of an unlimited number of Dracal sensors on the same computer
- Simultaneous and synchronized recording of all types of sensors
- Records captured data to text files (configurable format)
- The recording file can be viewed in real time (new values are added dynamically)
- Perfect synchronization with our Wi-Fi gateway
The Protocol Switcher is a handy little tool that enables Windows users to convert their VCP-equipped instruments between VCP and USB modes with a single click. This tool has been specially designed with calibration laboratories in mind, who are entrusted with the annual recalibration tasks for these sensors often integrated within industrial products (OEM integration).
Available in versions 3.4.0 and higher
- One-click conversion between VCP and USB modes
- Continuous sensor refresh mechanism (hot plug)
- Supports simultaneous use of an unlimited number of Dracal sensors on the same computer
The DracalView download comes with our free command line tool dracal-usb-get.
This tool, which DracalView shares the resources, allows you to directly access your data and gives you all the autonomy you need to integrate them into other programs.
- Works under Windows (Win7/8/10 64&32-bit), Mac OS X and Linux (instructions) available
- Simultaneous and synchronized recording of all types of sensors
- Sensor interrogation by unique serial number
- Export to stdout
- Configurable measurement units (°C, °F, Kelvin…)
- Code examples in numerous programming languages available
- One concrete example of integration within LabVIEW available
dracal-sensgate-get
The DracalView download also includes dracal-sensgate-get, a command-line-interface that provides wireless access to data from all the sensors connected to your SensGate. The tool is designed so that code already written with dracal-usb-get can also be used with dracal-sensgate-get, up to a simple “search and replace”.
This tool offers the same advantages as those for dracal-usb-get listed above, plus:
- Access data from any Sensgate-connected sensor, even those communicating via COM protocol (VCP option)
