Lorenz SI 2-channel USB sensor interface

Wednesday, 14 September, 2011 | Supplied by: Bestech Australia Pty Ltd


The Lorenz SI 2-channel USB sensor interface enables the output signals from two sensors to be connected directly to a PC. Sensor types compatible with the SI USB sensor interface include unamplified strain gauge bridge transducers, and voltage and current output transducers and transmitters. The SI USB includes software that enables the sensor signals to be logged and displayed graphically at up to 2500 samples/s.

Scaling factors and other parameters are saved in memory, so that calibration details need be changed only if the sensors are changed. A second-order, low-pass filter with user-selectable frequencies is included to eliminate spurious signals and noise.

The VS2 configuration and measurement software enables the data to be presented graphically with both channels on a common time base - the scaling of the y-axis is automatic, and the measured data is saved automatically as CSV and text files for export to spreadsheet programs. The system is also compatible with LabView.

The SI USB sensor interface for strain gauge sensors provides regulated 5 VDC excitation and accepts ±3mV/V output signals. The voltage output signal type provides 12 VDC and accepts ±5 VDC or ±10 V signals, and the current output type provides 12 VDC loop voltage for either 0-20 mA or 4-20 mA output signals. SI USB interfaces are also available with combinations for a strain gauge and a voltage or current output sensor, and variations of ±5 and ±10 VDC type sensors. All SI USB sensor interfaces require 100 to 240 VAC mains input voltage.
