The Transducer Block contains block parameters that configure the device’s functionality. It insulates the sensor
characteristics and signal conditioning from the other device Function Blocks. Specifically, it interprets the sensor
signal based on configured values, applies factory and process calibration data, compensates for temperature and
process effects, and converts the resulting values in the configured Engineering Units that can be used by the Analog
Input Blocks contained within the device.
The following diagram illustrates the Transducer Block design. The following table lists the Transducer Block
parameter information.
