FAQ#110 - What's the purpose of the linear and polynomial factors written in the Calibration Reports?

Utilize the Linear Sensitivity Factors (A, B) and Ploynomial Sensitivity Factors (A, B, C, D) of the Calibration Reports permit to obtain readings in engineerig units with a maximum error as for the Calibration Report.

In the case of analogue gauges, the factors shall be applied on the electrical readings (i.e. mA, mV, digit, etc...)

In the case of digital gauges in "Legacy mode" (digital gauges with FW version 0.X, 1.X, 2.X or 3.X), the factors shall be applied on the output in engineering units (i.e. sin angle, kPa, etc...)

In the case of digital gauges in "Normal Mode" (digital gauges with FW version 3 or higher), the factors are already applied inside the gauge, so the Sensitivity Factors shall not be utilized with these instruments.
NOTE: all the new digital gauges are in "Normal mode".

For more information regarding SISGEO Calibration Report, refer to the following video https://youtu.be/BF8e3ZRcaYU

For more information on "how to use" the Sensitivity Factors with analogue gauges and with digital gauges in Legacy Mode, refer to the instruments manuals or to the following document: https://www.sisgeo.com/uploads/manuali/Addendum_data_processing/ADDENDUM_-_DATA_PROCESSING_-_EN_00.pdf

FAQ#088 - Which is the IP protection class of Sisgeo junction boxes?

Sisgeo junction boxes have IP67 protection.
The IP class is granted if the cable glands are correctly tight and the cover is mounted respecting the right key position, as for the following pictures:

01 Junction box Sisgeo

 

02 Junction box Sisgeo

 

03 Junction box Sisgeo

 

 
FAQ#077 - Quelles sont les longueurs maximales de câble depuis l'instrument jusqu'à l'enregistreur de données?

 

 

 

 

Les longueurs de câble maximales dépendent de plusieurs facteurs, et en premier lieu le mode d'installation et les protections de câble (blindage, terre, etc...). En supposant que les instruments sont installés selon les règles de l'art, les suggestions suivantes devraient être prises en compte pour la longueur maximale de câble:

INSTRUMENTS NUMERIQUES: voir FAQ#073

INSTRUMENTS ANALOGIQUES: voir ces deux documents:
