SensorCore

The SensorCore(SC or SCA) is designed as a low-cost, low-power data logger for the most demanding analog data-acquisition applications.Featuring up to 48 channels of ADC inputs, 2 RS232/RS485 ports, CompactFlash interface, and a high performance 10/100M BaseT Ethernet.The SensorCore out-performs desktop-based acquisition solutions for a fraction of the price.

The SC features three high-speed LTC2448 sigma-delta ADCs. Each LTC2448 chip offers 8 ch. differential or 16 ch. single-ended input channels (up to 48 channels if all 3 chips are installed).Variable speed/resolution settings can be configured. A peak single-channel output rate of 5 KHz can be achieved. At a sample rate of 1.76KHz, readings are accurate at up to 18+ bits in basic experimental conditions. The LTC2448 works well directly with strain gages, current shunts, RTDs, resistive sensors, and 4-20mA current loop sensors.The SC can also work well directly with thermocouples in the differential mode. With a Type T thermocouple, we can have 200+ ADC counts per degree C. There are 8+ million counts of resolution in the input span. If desired, you could put a divider at the input to increase the input range.The SCA can have up to 6 high-speed 12-bit parallel ADC chips (AD7852) installed, each chip providing 8 channels analog inputs, with up to 300K samples per second. The AD7852 includes sample-and-hold, a precision internal reference, and has an input range of 0-5 V.
