DIGITAL PROCESS INDICATORS
Overview
The Digital Process Indicators are basically DVM’s designed to fulfill the requirement of
accurate Measurement and display of various electrical parameters in Process Industries. The
standard range consists of 3 1/2 digit (Max. count value 1999) & 4 1/2 digit (Max. count value
19999) indicating meters available in 96 X 96 mm and 96 X 48mm Panel mounting type
enclosures.
The units use Dual Slope integration method for digitizing the analog inputs & offer excellent
linearity over the entire range. A temperature compensated reference ensures minimum
drift with wide changes in ambient temperatures.
