24bit DAQ card debuts for load cell measurements

Adlink Technology Inc. announced the PCI-9524, its first 24bit high resolution PCI DAQ card for load cell measurements. Designed specifically as a single-board solution for material testing system (MTS) applications, the PCI-9524 integrates 24bit load cell measurement, four channels of general-purpose analog input, two channels of general-purpose analog output, three channels of pulse-wave modulation output, 16bit isolated digital I/O and a three-axis encoder.

The PCI-9524 combines a high 24bit resolution with 1/200,000 count accuracy to provide the most precise load cell measurement PCI board available in the market today, said the company.

"The high precision of the PCI-9524 is achieved through the use of a remote sensor circuit to monitor the excitation voltage of the load cell sensor," explained James Gau, VP of measurement and automation product segment at Adlink. "When the resistance of the leads causes a drop in excitation voltage, this circuit will provide automatic voltage compensation."

Other technologies implemented in the PCI-9524 include an auto-zeroing feature to reduce semiconductor noise, thermal noise and thermal coupling. Analog and digital filters further reduce RFI and other electrical noise that may occur.
