A deadweight tester is a tool used for assessing, setting, calibrating, or repairing pressure devices and for testing the pressure of a liquid.
What Is A Deadweight Tester?
A deadweight tester is a calibration standard that uses the principle of a pressure balance for the calibration of electronic or mechanical pressure measuring instruments. Deadweight testers use pressure and check the precision of their test subjects. With this tool, technicians can maintain the quality and accuracy of pressure measuring analyzers.
How Do Deadweight Testers Work?
Deadweight testers use calibrated weights and are operated via oil (hydraulic) or air (pneumatic) for a variety of applications that include calibrating all kinds of pressure gauges such as industrial pressure gauges, pressure transmitters, and more. Deadweight testers offer cutting-edge technology to generate pressure and precisely control and measure it within the instrument. The pressure measurement of a gas or liquid allows an analysis of that device.
Deadweight Tester Equation
The basic equation that deadweight testers use is the weight force divided by the piston-cylinder area. The equation is as follows: P = F/A or Pressure = Force/Area. This equation is key to understanding how the tester calculates the resulting data.
Deadweight Tester Features
- Excellent piston assembly pressure range
- ISO/IEC 17025 accredited calibration certificate standard
- PressCal software
- Abilities to select nominal increments in psi, bar, or MPa pressure units
- Durable non-magnetic stainless-steel weights
- User-friendly applications
Note: Features may vary depending on the model.
Deadweight Tester Applications
Deadweight testers have a variety of components. There is the instrument base, piston-cylinder, and weight set. The instrument base comprises all the items needed for operation. This includes a hand pump, intensifier, oil reservoir, test station, adjustable feet, and piston float reference. The piston-cylinder is a durable and stable cylinder that is the main component of deadweight testing. The weight set consists of non-magnetic stainless-steel weights to increase the mass and allow for pressure analysis.
How To Use A Deadweight Tester
- Set up the deadweight tester
- Note the environmental conditions at play
- Set the correct mass on the piston
- Increase the pressure under the piston until it floats
- Perform a full fundamental pressure equation calculation
- Review the data
- Make sure to pay attention to your testing requirements, specs, and data
- Record your results
Note: There is more than one way to use a deadweight tester, and preferred methods might vary from model to model.
