Comparison Pressure Calibrator Range 0 to 700 Bar

High Accuracy Hydraulic Comparison Test Pump for Pressure Gauge Calibration and Verification

The RAVIKA Comparison Pressure Calibrator Range 0 to 700 Bar is a precision-engineered hydraulic pressure calibration system specifically designed for accurate comparison testing and calibration of pressure gauges, pressure transmitters, pressure switches, pressure indicators, digital pressure gauges, and various pressure measuring instruments. This highly reliable comparison test pump provides a simple, economical, and accurate method of pressure calibration by generating hydraulic pressure and comparing the readings of the instrument under test against a calibrated master pressure gauge.

Pressure instruments play a vital role in industrial process control systems. Inaccurate pressure measurement can result in product quality issues, inefficient plant operation, equipment damage, safety hazards, and increased operational costs. Regular calibration is therefore essential to maintain instrument accuracy and process reliability. The RAVIKA Comparison Pressure Calibrator provides a practical solution for routine calibration activities in laboratories, workshops, maintenance departments, and industrial plants.

Designed with a precision screw pump mechanism, dual gauge mounting arrangements, and robust industrial construction, this comparison calibrator enables users to generate pressure smoothly and accurately up to 700 Bar. The unit is supplied with a complete set of accessories including adaptors, spare seals, spanners, dust cover, and instruction manual, making it ready for immediate use. The master gauge is not included, allowing users to select a reference gauge according to their required accuracy and calibration standards.

What is a Comparison Pressure Calibrator?

A comparison pressure calibrator is a device used to calibrate pressure instruments by comparing their readings against a known reference standard. The method involves exposing both the reference gauge (master gauge) and the instrument under test to the same pressure source and comparing the readings at various pressure points.

The comparison calibration method is widely accepted across industries because it is:

• Simple to perform
• Cost-effective
• Highly reliable
• Accurate for routine calibration
• Suitable for laboratory and field applications

When connected to the same hydraulic pressure source, both instruments should indicate identical readings. Any difference between the readings indicates calibration error in the instrument being tested.

Working Principle

The RAVIKA Comparison Pressure Calibrator operates on a hydraulic pressure generation principle.

The master gauge and test gauge are connected to separate gauge mounting stations provided on the calibrator. Once connected, pressure is generated using the integrated hydraulic screw pump. As pressure increases, both instruments are subjected to the same pressure conditions.

The operator gradually increases pressure and compares the readings of both instruments at predetermined calibration points. Any deviation observed can then be corrected or documented.

Because both instruments are exposed to identical pressure simultaneously, the comparison method provides reliable and repeatable calibration results.

Precision Hydraulic Screw Pump

The core component of the calibrator is the precision hydraulic screw pump.

Unlike conventional pressure generation systems, the screw pump offers superior control over pressure generation and adjustment.

Advantages of the Screw Pump

• Smooth pressure generation
• Fine pressure adjustment
• Stable pressure holding
• Minimal pressure fluctuation
• Accurate calibration point setting
• Reduced operator effort

The screw mechanism allows gradual pressure increase, making it easier to achieve exact calibration points without overshooting.

This feature is particularly useful when calibrating high-accuracy pressure instruments where stable pressure conditions are essential.

• Accurate pressure adjustment

These advantages improve overall calibration productivity and reduce downtime.

Importance of Pressure Calibration

Pressure instruments gradually drift over time due to:

• Mechanical wear
• Vibration
• Temperature variations
• Process conditions
• Continuous operation
• Aging components

Regular calibration helps maintain:

• Process accuracy
• Equipment safety
• Product quality
• Regulatory compliance
• Operational efficiency

The comparison calibration method provides a practical and economical solution for maintaining pressure instrument accuracy.

Master Gauge Not Included

The calibrator is supplied without a master gauge.

This provides flexibility to users who may already possess a certified reference gauge or require a specific accuracy class suitable for their calibration standards.
