Differential pressure transmitter for industrial process fluids, provided with compensation of static pressure change effects |
摘要 |
A differential pressure transmitter for process fluids is of the kind having a measuring transducer with a closed cell containing a filling liquid and a measuring diaphragm on both sides of which are arranged resistive, capacitive or inductive elements which are capable of converting a diaphragm deflection induced by differential pressure applied to the cell into electrical quantity changes. Inside the cell is provided at least one pressure sensitive component which is subjected to the pressure (s) of the filling liquid and is capable of providing an electrical output in accordance with the pressure values. This component is preferably a pasted carbon resistor, which permits output processed signal compensations in an electronic processing circuit to be made so as to minimize the effects of static pressure changes.
