FAQ#116 – How do I configure a WR-Log digital node to read RS485 Sisgeo TIMED sensors?
Sisgeo digital instruments can operate in two powering modes: TIMED or ALWAYS-ON (for more information see F.A.Q.#094.A string of mixed instruments consisting of TIMED gauges and ALWAYS-ON gauges cannot work.The first thing to do is therefore to check that ALL connected instruments in your array are set to TIMED mode.You can check the powering mode […]
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#015 – The anchor load value displayed on the load cell manometer or readout does not agree with load calculated by the hydraulic jack. What’s right?
The main factors which influence the anchor measurements are: – axial misalignment of the jack– difference in diameter between the jack and the load cell. These factors cause bending of the bearing plate between the load cell and the jack and affects the response of the cell. To minimise this effect use the genuine distribution […]

Miniera di Chuquicamata
Chuquicamata è una miniera di rame a cielo aperto, in cui un minerale relativamente povero di rame è estratto in quantità enormi. Le moderne tecnologie di fusione ed estrazione mineraria permettono l’uso di tali depositi a costi molto bassi. Il minerale contiene metalli tra 1,13% e 1,18%, di cui rame in maggior quantità, ma anche […]
