SMARTbrick 3500A – PT100 / PT1000 EMULATOR

Elektronisches Emulieren eines Temperatursensors vom Typ PT100/PT1000 als ohmscher Widerstand

With the SMARTbrick 3500A, a PT100/PT1000 type temperature sensor is electronically emulated as ohmic resistance via an analog-digital control circuit. The single-channel resistor emulation emulates an electrical “two-pole network” and is galvanically isolated from the remaining test system. A line break / short-circuit can be stimulated individually for each channel for error stimulations. The resistance value, sensor type and the error stimulation are specified in connection with the carrier board via CAN bus.
