-
The ProDAQ 5821 series of Signal Conditioning Cards is designed to interface with a variety of sensors, principally RTDs, Thermistors, Cryogenic Diodes and Voltage type sensors. Each version of the 5821 provides the capability of precise 4-wire measurement. In order to achieve this, a precise 500μA constant current source is provided per channel. The current source can be disabled on a per channel basis and is monitored to ensure that current is flowing. The value of the output current is stored on-board after calibration. In order to achieve the highest accuracy the output current may be automatically calibrated 'on-the-fly' using the ProDAQ 3416 24-bit Sigma-Delta ADC card and an on-board precision resistor.
