Calibration of Weight Indicators

This are some of the best gedge system weight indicator calibration

What Is A Weight Indicator? Weight Indicator Calibration, specifically Digital Indicators, can record measurements, usually as an actual value, such as 20.00 mm, and transmit the data directly to a computer or printer or SPC programs with no operator errors in recording or reading. With an SPC program installed, the operator receives a record of the measurement results in a database table or spreadsheet format and interprets them through performing statistical analysis.

A Digital Indicator also provides switching between units with an easy press of a button-  no need to type into a calculator or search into a browser just to get the separate unit conversion. Digital Indicators only have a single moving part which demands less frequent cleaning compared to other mechanical devices. With Digital Indicators now offering IP Ratings, you can never worry about using them in wet, dusty or other harsh environments making them such a great investment for your business. 

Why Do You Need To Calibrate A Weight Indicator Calibration?

Indicators, no matter how excellent the quality is, degrades with time and use. In order for every equipment to measure parts accurately, they must be calibrated from time to time. This applies to all hand tools or equipment that is commonly used in a busy environment (mostly manufacturing) where they are used to check the quality, quantity and weight of every product being produced.

Referred to as the process of comparing two measurement devices against each other and the documentation of this comparison, Calibration uses one device against another (commonly referred to as a calibrator) to use it as a traceable reference standard. Once the result is recorded, the equipment is then considered to be calibrated. Calibration of weight indicators has three purposes: it checks the accuracy of the instrument, determines the traceability of the measurement and it repairs the device if it is out of calibration.

This usually involves a report provided by the calibration expert, showing the error in measurements of the measuring device before and after the calibration. It is extremely important to calibrate equipment to help assure accurate measurements and production of quality products with minimal errors and recalls. Thanks to calibration, any error or uncertainty of the measuring device is resolved by ensuring the accuracy of the test equipment.

How Do You Inspect A Weight Indicator?

  1. First, better check for sticking. You can do this by slowly moving the spindle from the rest position to its maximum limit of travel and then return through hand pressure.
  2. Next, you have to check for any looseness on the spindle. This could be achieved through pushing the spindle back and forth in a perpendicular direction. Next, you better inspect the rack pin side by rotating the spindle. While doing this, you can record any deflection.
  3. Check if the return spring pressure is uncontrolled or going more than expected.

How Do You Calibrate An Indicator?

  1. First, make sure that the dial indicator is secured on the calibrator.
  2. Next, make sure to make four readings on its first revolution. 
  3. This would normally depend on the indicator being calibrated, but make around 6-10 readings over its full range, just to be one hundred percent sure.
  4. Start retracing the readings being shown on your indicator at the same corresponding points. 
  5. Check if the difference that is being presented between errors in both inward and outward position is “hysteresis” which is a usual failure that is common in used indicators.
