DATAQ Instruments announces an improved mid-range USB data acquisition (DAQ) starter kit, model DI-1110. This new instrument replaces model DI-149 with a superior feature list and much better price/performance. You won’t believe what $89 can buy. Let’s compare the new DI-1110 to the product it replaces:
As you can see, the DI-1110 substantially raises the price/performance bar. Just like the DI-149, the DI-1110 provides armored, differential analog inputs and discrete I/O, a .Net Class for writing your own Windows programs, and a documented protocol for other operating systems. Beyond that, the picture changes dramatically. Let’s look at the details:
Data Acquisition Resolution
With two more ADC bits, the DI-1110 offers four times the measurement resolution of he DI-149. What does this mean? Let’s assume that you connect a load cell with a 1000 lb. range and a 4-20 mA output to both a DI-149 and the DI-1110 using a 250 Ω shunt resistor. The smallest load change you can measure using the DI-149 is 4.9 lbs. With the DI-1110 you can resolve 1.2 lbs. If you just measure voltage, resolution values for the DI-149 and DI-1110 are 19.5 mV and 4.8 mV respectively.
Data Acquisition Sample Rate
Do you need fast? The DI-1110 takes”fast” to a new level for an $89 product. The DI-1110 tops out at 160 kHz, or one sample every 6.25 µS. Compared to the DI-149’s 10 kHz maximum rate, the DI-1110 easily captures the fastest transients and events.
