You have pressure sensor, which contains:
- primary transducer - analog&digital electronics . You have onboard some voltage (or other) precision refence , so You can make self-calibrate procedure/circuit for electronic part. This will eliminate errors as far as reference is stable. If You have tables/furmulaes for specific drift of electronics or reference, You can make corrections with these tables . If You have tables/furmulaes for specific drift of primary transducer, You can make corrections with these tables for corrections. But drifts ,caused in primary transducer by unexpected stresses , cannot be compensated this way in loaded condition . regards |

a miserable sensor, why the requirement | 01/01/70 00:00 | |
I dont require precision... | 01/01/70 00:00 | |
Can anyone I dentify its manufacturer | 01/01/70 00:00 |
