DIGITAL_OIL_PRESSURE_GAUGE

Published:2009/7/9 3:39:00 Author:May | From:SeekIC

This gauge uses a sensor in conjunction with R1 to develop a dc voltage proportional to oil pressure. IC1 and IC2 form a two-digit DVM. Q1 and Q2 are display selectors for the multiplexed display. IC1 provides the necessary +5V to the circuitry. Calibration is via R11 and zero adjust via R17.
