Single Phase Digital Dial Indicator High Precision Support For
Modbus-Rtu Protocol
1. Description:
Digital indicators have some advantages over their analog
predecessors. Many models of digital indicator can record and
transmit the data electronically to a computer, through an
interface such as RS-485. This facilitates statistical process control (SPC), because a computer can record the measurement results in a
tabular dataset (such as a database table or spreadsheet) and interpret them (by performing statistical analysis on them).
This obviates manual recording of long columns of numbers, which not only
reduces the risk of the operator introducing errors (such as digit transpositions) but also greatly improves the productivity of the process by
freeing the human from time-consuming data recording and copying
tasks. Another advantage is that they can be switched between
metric and inch units with the press of a button, thus obviating a separate unit conversion step of typing into a calculator or web browser and then typing
the results.
