What is a Dead Weight Tester used for?
A Dead Weight Tester is a precision instrument used to calibrate pressure gauges, transmitters, and other pressure sensing devices. It operates on the principle of Pascal’s law, where pressure is directly proportional to force over area. Purpose:
- Calibration: Primarily used for calibrating pressure gauges, transmitters, and other pressure sensing devices.
Working Principle:
- Pascal’s Law: Pressure is directly proportional to force over area.
- Known Mass: Utilizes a known mass (dead weight) placed on a piston-cylinder assembly.
- Pressure Generation: Dead weight exerts force downwards, creating pressure within the piston-cylinder assembly.
- Pressure Transfer: Pressure generated is transferred to the device under test (DUT) through a fluid connection.
Applications:
- Industries: Commonly used in oil and gas, aerospace, manufacturing, and research laboratories.
- Precision: Provides highly accurate and reliable calibration results.
Dead Weight Testers are indispensable tools for maintaining the accuracy of pressure instruments in various industries. .
