Data Conversion
The data values transmitted by the interface module fall in the range from -29490 to -9830.
Each incremental integer represents 0.0089 psig. For example, an output value of -29490 is
equivalent to 0 psig, whereas an output of -28366 is equivalent to 10 psig.
The module has been configured to display output data values as numerical values. Calculate
the difference between the minimum value (-29490) and the output value (x), then multiply
by 0.0089.
NOTE: The output value will be a negative integer. Multiply the formula by -1 to convert the
negative integer to a positive one.
For example, where the output value equals 13500, the calculation is as follows:
(-1) × (-29490 - (x)) × 0.0089 = pressure (psig)
(-1) × (-29490 - (-13500)) × 0.0089 = 142.31 psig
