Virtual Dial Indicator – Simulator of Use in Thousandth Inch

Relógio comparador; Dial Indicator; Reloj comparador
Simulator of use, reading and interpretation of Dial Indicator or Dial Gauge in thousandth inch

This instrument reading is similar to the dial indicator in millimeter of hundredth resolution, the display is recorded in the same way in both cases, the difference is in the gear ratio between gear teeth and pinion inside. So, we recommend you to familiarize with the science of its reading interacting with the page: Simulator of Dial Indicator in millimeter with hundredth resolution (0,01mm) and later come back to understand the difference.

Roll down the page to interact with the simulator of reading and interpretation of dial indicator in thousandth inch, drag and drop in the vertical the detail in orange.

Dial Indicator or Dial Gauge in inch and the science of its reading

A full turn of the main pointer of our simulator represents the equivalent of one-tenth of an inch of spindle motion. This display has ten numbered divisions (from 0 to 90 from ten in ten) and each of these is subdivided by ten smaller strokes, making a hundred (100) divisions. In this way each of the markings on the dial is equal to one hundredth of a tenth of an inch (1/10/100 or 0.001 in). The span (nominal range) of the instrument represented by the simulator is 1,000 in. (To circumvent the limitations imposed by the resolution of the monitors, the span (nominal range) of this Comparator Clock Simulator is 0.114 in); This feature makes it necessary for some device to count the number of turns of the main pointer, this device is the smallest pointer. Thus, when the smaller pointer sweeps its ten divisions it means that it ran ten tenths of an inch (10/10), or one inch.

Simulator of Reading and Interpretation of Dial Indicator in thousandth inch

In the Dial Indicator below, drag and drop, in vertical, the detail in orange for reading

tip: turn the big display of Indicator

– turn the big display of indicator
– click in the ‘eye’ icon to hide the measure
– click in the ‘locker’icon to cancel the spring effect of instrument

note: by limitations imposed by monitor resolution the
distance runned by the contact point is no proportional to the indicated one
