Pressure measurement because atmospheric pressure is always changing and the reference in this case is fixed at 1 bar. To produce an absolute pressure sensor, the manufacturer seals a high vacuum behind the sensing diaphragm. If the process-pressure connection of an absolute-pressure transmitter is open to the air, it will read the actual barometric pressure. The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N·m or kg·m·s). This special name for the unit was added in 1971; before that, pressure in SI was expressed in units such as N·m. When indicated, the zero reference is
Comparison of Pascal and Delphi Instead, reading through eoln in Delphi gives the character code for carriage return (13), followed by line feed (10). 8. Numbers and booleans are not printed out in their 'default' field widths by Delphi's version of the Write and WriteLn standard procedures, being instead printed in the minimum amount of space. For example, in Delphi, is equivalent to: However, Standard Pascal requires it to be equivalent to the following (TotalWidth is implementation-defined): Similarly, for booleans, is equivalent to in Delphi, but in ISO 7185. 9. Temporary files are not supported by Delphi using traditional Pascal I/O - executing Reset() or
