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:
FAQ#077 - Which are the maximum cable lengths from instrument to datalogger?
The cable lengths depend from many factors, first of all installation and cable protections (screen, earth, etc...). Assuming that instruments are installed in a workmanlike, for the maximum cable lengths should be followed the next suggestions:
DIGITAL INSTRUMENTS: see FAQ#073
ANALOGUE INSTRUMENTS: see both documents:
