The unit is capable of generating vacuum up to -710 mmHg, making it suitable for a wide range of industrial vacuum calibration applications. The calibrator is equipped with a precision screw pump, dual gauge mounting stations, vacuum isolation system, atmospheric release valve, and a sturdy base plate for stable operation. A complete accessory package is supplied including adaptors, spare seals, spanners, dust cover, and instruction manual. The master gauge is not included, allowing users to select a certified reference gauge suitable for their specific calibration requirements.

What is a Comparison Vacuum Calibrator?

A comparison vacuum calibrator is a vacuum generation device used to calibrate vacuum instruments by comparing their readings with a calibrated reference instrument known as a master gauge.

In the comparison method, both the master vacuum gauge and the instrument under test are connected to the same vacuum source. The vacuum generated within the circuit is applied equally to both instruments. The readings are then compared at various calibration points to determine the accuracy of the instrument being tested.

This method is one of the most practical and economical calibration techniques used in industrial maintenance and laboratory environments.

Working Principle

The RAVIKA Comparison Vacuum Calibrator operates using a manually controlled screw pump mechanism designed to generate vacuum within a closed calibration circuit.

The master gauge and the vacuum instrument under test are mounted on the two gauge connectors provided on the calibrator. As the screw pump is operated, vacuum is gradually generated within the system. Since both instruments are connected to the same circuit, they experience identical vacuum conditions.

The operator compares the readings displayed by both instruments and identifies any deviations. Calibration adjustments can then be made if required.

The system also includes an atmospheric release valve that allows the vacuum circuit to be connected directly to the atmosphere for quick zero verification of the gauges before calibration begins.

Vacuum Generation up to -710 mmHg

The calibrator is capable of generating vacuum up to -710 mmHg, covering the majority of industrial vacuum measurement applications.

This vacuum range is suitable for calibration of:

• Vacuum Gauges
• Compound Gauges
• Vacuum Transmitters
• Vacuum Switches
• Digital Vacuum Indicators
• Pressure-Vacuum Instruments
• Vacuum Sensors
• Laboratory Vacuum Instruments
• Process Vacuum Monitoring Devices

The wide operating range makes the calibrator highly versatile and suitable for both workshop and laboratory environments.

Precision Screw Pump for Accurate Vacuum Generation

At the heart of the system is a precision-engineered screw pump designed specifically for controlled vacuum generation.

Benefits of the Screw Pump

• Smooth vacuum generation
• Fine vacuum adjustment
• Stable vacuum conditions
• Accurate calibration point setting
• Easy operation
• High repeatability

The screw pump enables technicians to generate vacuum gradually and precisely, eliminating sudden pressure fluctuations that could affect calibration accuracy.

This level of control is particularly important when calibrating sensitive vacuum instruments.

Dual Gauge Connection Arrangement

The RAVIKA Comparison Vacuum Calibrator is equipped with two dedicated gauge connectors fitted with ½” BSP connections.

Configuration

• One connector for the Master Vacuum Gauge
• One connector for the Instrument Under Test

Both instruments are exposed to the same vacuum source, allowing direct and accurate comparison of readings.

Advantages

• Simultaneous calibration
• Faster testing process
• Improved accuracy
• Reduced setup time
• Easy instrument mounting

The dual connector arrangement makes the calibration process simple and highly efficient.

Atmospheric Release Valve for Zero Verification

A special valve is incorporated into the vacuum circuit that allows connection to atmospheric pressure.

Purpose of the Valve

• Quick zero checking
• Verification before calibration
• Easy vacuum release
• Safe operation
• Faster testing cycle

Before starting calibration, operators can connect the system to atmosphere and verify that both gauges return to zero correctly. This ensures confidence in the calibration results and helps identify any instrument issues before testing begins.

Sturdy Industrial Base Plate

The entire calibrator assembly is mounted on a heavy-duty base plate with supporting legs.

Benefits

• Stable operation
• Reduced vibration
• Better handling
• Improved portability
• Enhanced durability

The sturdy construction makes the calibrator suitable for continuous industrial use and field service applications.

Importance of Vacuum Calibration

Vacuum measurement plays a critical role in numerous industrial processes.

Inaccurate vacuum readings can result in:

• Product quality issues
• Process instability
• Reduced equipment efficiency
• Energy losses
• Safety concerns
• Increased maintenance costs

Routine vacuum calibration helps maintain:

• Measurement accuracy
• Process reliability
• Product consistency
• Equipment performance
• Compliance with quality standards

The RAVIKA Comparison Vacuum Calibrator provides a dependable method for maintaining vacuum instrument accuracy.

Standard Accessories Supplied
