USB data logger is high speed and high resolution

The CDL01-USB can supply the excitation current for sensors such as strain gauges, load cells and pressure transducers up to 300mA from a USB port, or up to 600mA using an auxiliary power supply.

The CDL01-USB compact, high speed, high resolution data acquisition and logging module from Celsum Technologies is a versatile tool that has five analogue input channels, five digital outputs, one analogue output, one digital input, and one counter input.

The device connects to a computer using a USB port, and the supplied Sensors2USB software allows the channels to be configured and named, and the data scaled, displayed and stored.

It has a maximum resolution of 21 bits (one part in 2,097,152 or 0.00005%), and a maximum sampling rate of 50,000 readings per second, ie, 50kHz.

The counter input has a resolution of 32 bits and a maximum speed of 5MHz.

The analogue inputs range from +/-10mV through to +/-10V full scale.

The CDL01-USB is supplied in a robust aluminium case measuring only 92x57x20, with a 26-pin D-socket for field connections to sensors .

among the available accessories is a screw-terminal break-out box to enable easy connections, adaptor cables, customised wiring harnesses, and an independent sensor excitation power supply.

Roy Carter, Celsum Technologies's managing director, said: "We are very excited about the CDL01-USB.

"This is an excellent instrument that can be quickly connected and configured to take readings from a wide range of sensors, and, via its digital and analogue outputs, can be used to control the subject equipment.

"It complements our range of instrumentation, and has many applications in research and development, quality control, testing, and process monitoring and control.".
