| Notes | |
| Note 1 | 0barG=101.325kPaA (define 1 atm as 0bar) |
| Note 2 | Default full-scale output is 4.5VDC without clamping. If the product is overloaded the output exceeds 4.5VDC but remains linear with input pressure; with continued overload the output cut-off voltage is 4.95VDC. |
| Note 3 | High temperature and high humidity storage will oxidize and discolor the brass connector and pure copper housing; this does not affect sensor function or performance. |
