Low pressure sensor has differential expansion compensation of internal air volume uses strain gauge measurement is cheap and accurate |
摘要 |
The low pressure sensor exactly compensates for temperature dependent variation of the small internal gas volume (5) by differential expansion between copper housing (1) and an inner piece (2) so as to keep the membrane (3) shape dependent only on pressure which is recorded by the strain gauge (4) on the housing.
