Systems Measure Temperature And Voltage Accurately

Consisting of a plug-and-play PCI board, cable and screw terminal signal conditioning pod, the DaqTemp Series is said to provide an all-in-one-box means of accurately measuring temperature, voltage, frequency, and pulse count, as well as providing digital I/O and analog outputs. Available with either seven or 14 thermocouple input channels, the new PC-based data acquisition systems use built-in cold junction compensation to deliver precise thermocouple measurements: channel-to-channel variation and noise are less than 0.2°C and accuracy is better than 1.0°C. Besides thermocouple inputs, the DaqTemp Series also comes equipped with seven differential voltage input channels offering 16-bit resolution and 13 programmable full-scale input ranges of ±156 mV to ±10V. The systems also offer four channels for measuring frequency or count pulses up to 10 MHz. All inputs can be synchronously scanned up to 200 Kreadings/s to provide time correlation between inputs. And all power requirements are met by the PC. Price of the top-of-the-line DaqTemp—it offers 14 differential thermocouple inputs and four analog outputs—is $1,999; the price includes DaqView Out-of-the-Box software, which eliminates the need for programming.
