D62T 45300 - Temperature Transmitter
The temperature transmitter D62T 45300 converts the measuring values of Pt, Ni or TC sensors temperature linear in 0/4 to 20 mA or 0 to 5/10 V standard signals. The simple programming via the USB interface or alternatively the calibrated range selection via DIP switches and the compact housing is flexible to use. The high reliability and safe 3-port isolation are other features that guarantee the safe system operation.
The File menu
Using the File menu, you can load, save and document your configurations, either as a printout or as a PDF file.
The Device menu
In the device menu, you can transfer the configuration to the connected device or load it from the device.
In addition, you can open a diagnostic window to view the current measured values and status of the device.
The Settings menu
In "Settings", select the programme language.
The Help menu
In the help menu you can access the online help. You can also press [F1] at any time to call up the help for the selected element.
"About DRAGOset" provides you with information on the program.
Data record load/save
Data records can be saved in files and transmitted to the device or transmitter. Likewise, data records can load from the device or file into DRAGOset.
Measuring point number
For a printout or PDF documentation of the device settings, you can assign a measuring point number (Tag) to the device or transmitter. The number can be saved in the device, so the device every time indicates each reading with his Measuring Point Number.
The Measuring Point Number can have up to 16 characters, so the code is according to DIN EN 60617, and EN ISO 10628 (previously DIN 28004) in the device.
Sensor and compensation
In the selection "Sensor", select the sensor type that you will connect to the transmitter.
Compensation determines the type of connection that you make.
When resistance thermometers, such as Pt and Ni sensors:
|4-wire:||A 4-wire connection has the advantage that there are separate
lines for the sensor current and for the measurement. The cable
resistance has no influence.
|3-wire:||Important in a 3-wire connection is that all wires have the same
cross-section. The voltage drop is detected on only one side of
the sensor and it is assumed that the line on the other sensor
side produces the same voltage drop.
|2-wire:||In the 2-wire measurement the cable resistances add to the
measured value. The cable has to be as short as possible.
For thermocouples, the compensation items change in internal, external and off:
|internal:||The terminal temperature is detected internal in the transmitter.|
|external:||You have an external Pt100 sensor to a terminal block, which
measures the reference junction temperature.
|off:||The measured input value is not corrected.|
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:
|Sensor||Measurement range||min. Span|
|Pt 100, Pt 1000||-200 ... +850 °C||50 K|
|Ni 100||-50 ... +180 °C||50 K|
|Thermocouple Type J||-210 ... +1200 °C||50 K|
|Thermocouple Type K||-270 ... +1372 °C||50 K|
Output type and characteristics
Select one of 4 standard signal ranges:
0 to 20 mA, 4 to 20 mA, 0 to 10 V and 0 to 5 V.
The selected input range is linearly mapped to the output range. On the rising curve the measuring range begin corresponds to 0/4 mA or 0 V and the measuring range end corresponds to 20 mA or 5/10 V.
The falling curve turns the course. The transfer function of the transmitter 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 ... 20 mA||0.0 ... 20.5 mA||22.0 mA||0,0 ... 20.0 mA||0.0 mA|
|4 ... 20 mA||3.8 ... 20.5 mA||22.0 mA||4,0 ... 20.0 mA||4.0 mA|
|0 ... 10 V||0.0 ... 10.25 V||11.0 V||0,0 ... 10.0 V||0.0 V|
|0 ... 5 V||0.0 ... 5.125 V||5.5 V||0,0 ... 5.0 V||0.0 V|
DRAGOset calculates from your inputs the correct DIP switch programming. This image can also be found in the PDF documentation and the printout again.
If DRAGOset is not connected with the cable to the transmitter, you can transfer the switch settings manually to the DIP switches of the transmitter.
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.
Wiring of Terminals
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.
Products that are no longer available are hidden by default in DRAGOset.
