2.0 The Transducer Block
2.1 The Transducer Block
contains all of the manufacturer-specific parameters that define how the PR5350 Transmitter
functions. Selections such as setting of input type, engineering units, defining the dual func-
tionality when using the dual input, and so forth, are performed in the Transducer Block.
The transducer block in PR5350 allows the user to select a large number of sophisticated
functions. Therefore, the configuration of the transmitter must be carried out with the great-
est possible care.
2.2 The data of the Transducer Block Parameter List are grouped as follows:
2.8 AI_TRANSDUCER Block
2.8.1 Sensor characterising parameters
2.8.2 RTD / resistor specific parameters
2.8.3 Thermocouple specific parameters
2.8.4
Output conditioning parameters
2.8.5 Output parameters
2.8.6 Diagnostic parameters
2.8.7 Sensor error detection parameters
2.8.9 Sensor calibration parameters
2.9 PR_CUST_LIN Block
2.9.2 Linear Interpolation Linearisation
2.9.4 Custom Polynomial linearisation
2.10 PR_CUST_PRIV Block
2.10.1 PR_CUST_PRIV Block
All product-specific parameters are set off in grey background in the TB Parameter List. In order
to configure these parameters, the files mentioned in the introduction must be available to the
application software.
2.3 Default configuration
PR electronics delivers the transmitters with at default configuration which will suit the cus-
tomer’s demand in many cases. The configuration task has thus been reduced considerably.
The individual default configurations are shown in the TB Parameter List, but in short the de-
fault configuration is as follows:
Pt100 acc. to the standard EN 60 751 (2.8.1 LIN_TYPE, value 102)
°C (2.8.1 PRIMARY_VALUE_UNIT, value 1001)
3-wire connection (2.8.2 SENSOR_CONNECTION, value 1)
Only sensor 1 (2.8.4 SENSOR_MEAS_TYPE, value 220)
No sensor error detection (2.8.7 SENSOR_WIRE_CHECK_1, value 3)
2.4 Your application set up.
In the Transducer block all parameters marked R / W can be adapted to suit any mea surement
in temperature, ohm or mV. The way of presenting the file data mentioned in the introduction
varies greatly from one piece of application software to the other. Some programs show drop
down menus in which the parameters must be selected via text lines, while other programs re-
quire the user to type in the numerical value of the parameter selection.
