Digilent’s WebDAQ Data Loggers For Remote Monitoring and Control

The Digilent WebDAQ series consists of stand-alone, internet-enabled data loggers, including the WebDAQ 504 vibration-acoustic data logger and the WebDAQ 904 universal input data logger. These data loggers can be remotely configured, monitored, and used to log a wide array of data from a diverse range of sensors, including accelerometers, microphones, RTDs, thermocouples, and more. The devices’ robust capabilities make them important tools for gathering and analyzing data across various industrial and research settings.

WebDAQ Series of Data Loggers

Digilent developed its WebDAQ devices as stand-alone data loggers capable of withstanding harsh industrial environments. Each model in Digilent’s WebDAQ series is designed for specific data-logging applications. The WebDAQ 504 vibration/acoustic data logger can simultaneously collect real-time data from up to four integrated electronics piezoelectric (IEPE) sensors, which include accelerometers and microphones. The WebDAQ 904 universal input data logger can monitor up to four analog inputs from sensors like strain gauges and load cells.

Stand-Alone Data Acquisition

The WebDAQ series of data loggers have a high-speed communication port for monitoring, logging, and configuration from anywhere using a TCP/IP protocol. The data loggers also have a built-in web server for accessing from any device and can send alarms and notifications via email or text messaging.

Both systems are equipped with four digital I/Os that can be used for triggers or alarms and have a 24-bit A/D converter. The WebDAQ 504 also features four simultaneous IEPE inputs and has a sample rate of up to 51 kS/s per channel. The WebDAQ 904 has four simultaneous analog inputs that can support voltage up to +60V, with a sample rate of up to 100 S/s per channel.

Remote Monitoring and Control

With the WebDAQ series, customers can log data internally or map it to their personal network. Both systems have 3 GB of memory. The WebDAQ data loggers also have flexible task scheduling, can export data in CSV, UFF, or binary format, and do not require driver software to install. The series also has Wi-Fi support, though a Wi-Fi dongle is not included with the purchase.

The WebDAQ series also features an embedded operating system (OS) and a built-in web server to prevent customers from buying costly software or a laptop or desktop to program and view their data. The web server has been optimized for desktop or mobile use. For those who need more custom functionality, Digilent provides customers with a RESTful API to start or stop acquisition, retrieve data, or access information about their system.
