Differential quasi-static pressure monitoring
PROCESSING MODES AND APPLICATIONS
7.14Differential quasi-static pressure monitoring
This type of processing is equivalent to that used for differential housing expansion
processing. See 7.11 Differential housing expansion.
7.15Quasi-static temperature monitoring
This type of processing is equivalent to that used for absolute housing expansion processing
(see 7.10 Absolute housing expansion), but using a temperature unit expressed in °C.
