Description
The transmitters detect sensor signals from resistance thermometers, thermocouples, resistance potentiometers/WFG or resistors/potentiometers. When using a resistance/potentiometer or resistance thermometer, the input-side sensor connection can be made in two, three or four-wire circuit. Voltage signals in the range of -100 ... +1100 mV can also be recorded. Depending on the choice of the measuring input, the linearization variants are linear, temperature-linear as well as the possibility of a user-defined linearization which can be easily configured. As output signal, the transmitter supplies 4 ... 20 mA or 0 ... 10 FROM The measuring input and the output signal are electrically isolated from each other. For both types, a revision of the output signal is possible. The transmitter can be configured with respect to the type of sensor, connection technology of the sensor, measuring range (freely adjustable) and linearization using a setup program on the PC. The connection to the PC is established via a USB interface, which does not require any additional auxiliary voltage. Via the USB interface the min./max. process value recorded by the transmitter, the min./max. -Operating temperature is read and the sensor wiring is checked online. The operating state of the transmitter is signaled by a two-colored control LED (red/green). In trouble-free operation, the lamp flashes green. If a fault occurs, such as B. Sensor breakage is indicated by a flashing code.
