In the testing and calibration laboratories, one instrument can be found commonly that is dead weight tester. The instrument is a reliable instrument that is used for the purpose of calibration of different pressure related instruments. Most of the industries rely on the dead weight testers for the calibration of pressure gauges. The instrument uses the pressure created by the hydraulics and pneumatics used in the instruments for the calibration of the instruments.
There are many different features of dead weight tester that make the instrument the most reliable method for calibration of the instruments like pressure gauges. Here are some of the best features of the dead weight testers that make it a primary standard.
- The instrument works on the principle of canceling the weight applied by the piston of the instrument through the weight applied by the calibrated weights.
- The dead weight testers are made from very high-grade materials hence, they are able to deliver highly reliable and accurate results.
- The seals used in the pneumatic or hydraulic pistons are of very high quality . Hence, there are no chances for any leakage of the pressure from them which may lead to wrong results.
- The common material used for making the pistons of the instrument is the tungsten carbide. This material offers a durable service life with accurate measurements.
Presto’s Dead weight tester is one such instrument that is used in a variety of calibration laboratories and industries for ensuring the best calibration process of instruments like pressure gauges.
