Title:
PROCESS VARIABLE TRANSMITTER
Document Type and Number:
Japanese Patent JPS5829096
Kind Code:
A
Abstract:
A process variable transmitter including a plurality of process variable detector units for detecting a primary process variable to be measured and secondary process variables not to be measured but which affect the primary process variable, a memory circuit for storing detected outputs supplied from the process variable detector units, a circuit for reading the detected outputs out of the memory circuit and then correcting the detected output indicative of the primary process variable based on the detected outputs indicative of the secondary process variables, and a power supply control for intermittently supplying electric power to the process variable detector units and the correcting circuit. The process variable transmitter corrects the primary process variable to precision and consumes a reduced amount of electric power.
