DRAGOset for Universal Transmitter D62T 46000
The Universal Transmitter D62T 46000 converts sensor signals from Pt, Ni, KTY or TC sensors to temperature linear standard signal 0/4 to 20 mA, 0/2 to 10 V, 0/2 to 10 mA or 0/1 to 5 V. With the mV and potentiometer input ranges further signals can be transformed into standard signals. Due to the easy configuration via USB interface the Transmitter is suitable for flexible use. The high reliability and the protective separation are further features, which ensure a safe system operation.
Under Sensor Type, select the sensor you are connecting to the transmitter.
The compensation adjusts the connection that you make.
When resistance thermometers, such as Pt, Ni and KTY sensors:
|4-wire:||Connection with 4 wires, it means there are separate lines for the sensor current and for measuring.|
|3-wire:||It is important for a 3-wire connection, that all wires have the same cable cross section. The voltage drop is detected only on one side of the sensor and it is assumed that the wire on the other side produces the same voltage drop.|
|2-wire:||In the 2-wire measurement, the lead resistances is added to the measured sensor resistance. It has to be as short as possible leads. You can compensate the line resistance manually when you specify the device, the sum of the lead resistances.|
For thermocouples, the selection options for compensation change in internal, external, and manual:
|internal:||The terminal temperature is detected by the transmitter.|
|external:||You have an external Pt100 sensor at a terminal block, which measures the junction temperature.|
|off:||The measured input value is not corrected.|
|manual:||Enter the reference temperature as a fixed value.|
Here you can set the desired measurement beginning and end of the measurement. The span, ie the area between the beginning and the end, shall not be less then minimum margin (see table). The possible settings are based on the operating temperature range of the sensors:

At the output, there are 8 common standard signal ranges available:
0 to 20 mA, 0 to 10 V, 0 to 10 mA, 0 to 5 V,
4 to 20 mA, 2 to 10 V, 2 to 10 mA, 1 to 5 V.
The selected measurement range is linearly mapped to the output range. On the rising characteristic the begin of measuring range corresponds to the 0/2/4 mA or 0/1/2 V, the end of measuring range to the 10/20 mA or 5/10 V. The falling characteristic reverses the course. The transfer function of the converter is shown graphically in DRAGOset.
The error signalisation defines whether errors will be left the output range. In this case, the output signal jumps to 22 mA, 11 V, 11 mA or 5.5 V, depending on the output selection.
Alternatively, the setting 0 mA, 2 mA, 4 mA or 0 V, 1 V, 2 V be chosen to signal the error, the output will remain in the range of measured values. This can be useful for example at a PLC input, that cannot handle signals out of range, the detection of the error then must be in the PLC.
|over range||in range|
|output type||output range||error signal||output range||error signal|
|0 to 20 mA||0.0 to 20.5 mA||22.0 mA||0.0 to 20.0 mA||0.0 mA|
|4 to 20 mA||3.8 to 20.5 mA||22.0 mA||4.0 to 20.0 mA||4.0 mA|
|0 to 10 V||0.0 to 10.25 V||11.0 V||0.0 to 10.0 V||0.0 V|
|0 to 5 V||0.0 to 5.125 V||5.5 V||0.0 to 5.0 V||0.0 V|
|0 to 10 mA||0.0 to 10.25 mA||11.0 mA||0.0 to 10.0 mA||0.0 mA|
|2 to 10 mA||1.9 to 10.25 mA||11.0 mA||2.0 to 10.0 mA||2.0 mA|
|2 to 10 V||1.9 to 10.25 V||11.0 V||2.0 to 10.0 V||2.0 V|
|1 to 5 V||0.95 to 5.125 V||5.5 V||1.0 to 5.0 V||1.0 V|
With the menu item "Device | Diagnostics ..." call to a diagnostic screen. In this window, you get an overview of the current measured values and messages of the transmitter.
This requires an online connection to the transmitter.
With the menu item "Device | Simulation" call to a simulation screen of the device. In the simulation input and output values can be simulated.
In addition, there is the commissioning function to check the following circuit parts with the complete measuring range. The commissioning function dynamical changes the output value. The output slowly sweeps over the complete measurement range, from the begin to the end value of the output range. The signal at 0 %, 50 % and 100 % of the range inserts a pause of a few seconds. It is possible to adjust the measurement range in this check.
When you leave the simulator window, the simulation output remains active, if you do not switch off before. As a reminder, therefore, the following window appears:
Depending on the selected sensor type and compensation changes the wiring of the transmitter. On this graph, you can see how the transmitter should be connected in this mode. If you move your mouse over the image of the transmitter, the terminal numbers are displayed.
DRAGOset shows the transfer function of the transmitter at the specified settings. You can see exactly the output value corresponding to the input signals.
If you move your mouse over the curve, the input and output value is displayed depending on the position of the mouse pointer.
