Pickering Interfaces has released the 40-262, an 18-channel variable-resistor module designed to simulate PT100 and PT1000 RTDs. The 3U PXI module can provide a resistance setting resolution of better than 10 mΩ over the entire resistance range and an accuracy of better than 0.1% for all resistance settings, according to Pickering.
Each simulation channel is able to provide a short-circuit or open-circuit setting to simulate faulty wiring connections to a sensor. Calibration of each resistor channel can be verified by connecting the calibration port to a digital multimeter.
