2.0 The Transducer Block 2.1 The Transducer Block contains all of the manufacturer-specific parameters that define how the T53 Transmitter functions. Selections such as setting of input type, engineering units, defining the dual functionality when using the dual input, and so forth, are performed in the Transducer Block. . . The transducer block in T53 allows the user to select a large number of sophisticated functions.

AI_TRANSDUCER Block (PA Slot 3) Parameter List 2.8.8 Sensor calibration, Description Sensor calibration is a very useful function when the transmitter output needs to be adjusted to the sensor signal, e.g. when the temperature sensor does not correspond to the ideal values for the selected temperature range. The results depend on the accuracy of the calibrator or reference equipment. In the following a temperature sensor calibration is described, however the principle can be used for all input types.

2.9 PR_CUST_LIN Block (PA Slot 4) Parameter List 2.9.1 Linear interpolation linearisation, Description LinType 1 = “Linearisation Table” generates a customer specific linear interpolation linearisation. Linear interpolation linearisation can be used on mV, ohmic and potentiometer signals.The linear interpolation linearisation is defined by straight lines drawn between the entered X / Y (input / output) coordinates. The linearisation table must consist of 10 to 50 coordinate sets.

function is particularly suitable for specific RTD sensors but also for non-linear ohmic signals if the user can accept to enter the input and output values of the polynomials in ohm and °C respectively. . Please remember that polynomial linearisation is absolute. The output value is calculated continuously according to the applied input value and the function formula. The max. input range can be limited precisely to the input range in which the polynomial linearisation will be used.
