Title:
DIFFERENTIAL PRESSURE TRANSMITTER FUNCTIONING AS HYDROSTATICVARIATION COMPENSATION FOR INDUSTRIAL RPOCESS FLUID IN COMBINATION
Document Type and Number:
Japanese Patent JPS6038634
Kind Code:
A
Abstract:
The differential pressure transmitter for process fluids is of the kind having a measuring transducer (C) with a closed cell (H) containing a filling liquid and a measuring diaphragm (M) on both sides of which resistive, capacitive and inductive elements are arranged, which are capable of converting the diaphragm deflection induced by the differential pressure applied to the cell into electrical quantity changes. Inside the cell at least a pressure sensitive component (RA,RB) is provided which is subjected to the pressure(s) of the filling liquid and 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 the electric processing circuit to be made so as to minimize the effects of static pressure changes.
