Dead Weight Pressure & Vacuum Calibrator – Precision You Can Trust
In industries where accuracy is critical—such as Oil & Gas, Pharmaceuticals, Power Plants, and Process Industries—pressure calibration is not just a requirement, it’s a responsibility. The Dead Weight Pressure & Vacuum Calibrator by Ravika Instruments is engineered to deliver unmatched precision, reliability, and long-term stability for both laboratory and field applications.
What is a Dead Weight Pressure & Vacuum Calibrator?
A dead weight calibrator is a primary standard instrument used for calibrating pressure measuring devices like gauges, transmitters, and switches. It works on the fundamental principle:
Pressure = Force / Area
By applying calibrated weights on a precision-machined piston-cylinder assembly, it generates highly accurate pressure or vacuum with minimal uncertainty.
Why Choose Dead Weight Calibrator?
1. High Accuracy & Repeatability
Calibrators are designed with tight tolerance piston-cylinder assemblies, ensuring exceptional accuracy and repeatability. This makes them ideal for NABL labs and critical industrial calibration tasks.
2. Wide Pressure Range Options
Available in multiple ranges to suit various applications:
- Low pressure (PSI / mbar)
- Medium pressure (Bar/ Kg/Cm2/ PSI Range)
- High pressure (up to 1000 Bar)
5. Superior Material Construction
- Non-corrosive and wear-resistant materials
- High-quality finishes for long service life
- Stable performance even in harsh environments
