Common thermal resistance:Platinum resistance、Copper resistance、Manganese resistance、Carbon resistance。
Operation:The thermal resistance in the transmission of resistance measurement signal,The three wire system,This is for when the transfer,To reduce the error of measurement caused by resistance of the wire。When the check its value,Should pay attention to which two wires for thread。
The answer to that
The parameter to be measured sensitivity is used to express the measuring instrument sensitive degree of change。Sensitivity caused by instrument measuring the change of the indicated value and the change of the ratio of the measured parameters variation。Sensitive limit is guidance instrument visible changes in the indicated value of the smallest change of the measured parameters。
The answer to that
Permissible error refers to the instrument in normal circumstances stipulated by the allowed maximum percentage error。The precision of the instrument refers to the permissible error remove percent(%)After the value。Precision grade is uniform provisions of the state,Divided into a series of standard percentage value。
