FAQ#111 – Why I cannot read correctly my 4-20mA current loop gauge?
It could be a problem connected to the power supply given by the readout or logger. When the power supply is in the current loop (2-wire gauge) it is necessary to consider the effect of voltage drop across the shunt resistor on the voltage applied to the gauge. For example, suppose a 4-20mA gauge requires […]
FAQ#037 – Which is the linear thermal expansion coefficient of the graduated flat cable (tape) of Water Level Indicators (WLI) and BRS settlement probes?
The linear thermal expansion coefficient of the flat graduated cable is 16x10E-6 m/ °C.
FAQ#033 – I have received the calibration Report of a piezometer. There is not the K Thermal Factor noted. In which way may I proceed?
If the value is not indicated in the Calibration Report, you should use this formula: K = -1 digit/°C For each degree of increase of temperature you should reduce 1 digit.
