PROTECTION OF PRESSURE MEASUREMENT TRANSDUCERS Pressure measurement transducers (also called pressure sensors or transmitters) are critical in industrial processes, medical applications, and scientific research. Proper protection is necessary to ensure accuracy, reliability, and longevity of these devices. The main protective measures include shielding against environmental factors, electrical disturbances, mechanical damage, and improper handling. Therefore, protecting pressure measurement transducers is essential for ensuring accurate, reliable, and long-lasting performance. Key Protective Measures 1.Environmental Protection: Shielding against temperature, moisture, corrosion, and dust. 2.Electrical Protection: Preventing Electromagnetic Interferences, voltage spikes, and grounding issues. 3.Mechanical Protection: Guarding against vibrations, overpressure, and physical damage. 4.Installation and Maintenance Best Practices: Proper selection, calibration, and wiring. 5.Industry-Sp...
ASTM E18-24: Rockwell Hardness Standard Test Methods
Introduction
ASTM E18-24 is a standard test method for Rockwell Hardness of metallic materials. This method provides the procedure for determining the Rockwell hardness of metallic materials by indentation with a diamond cone or a steel ball.
Test Procedures
- Prepare the sample surface.
- Select the appropriate indenter and load.
- Apply the preliminary test force (minor load).
- Apply the additional test force (major load).
- Record the hardness value.
