Simplifying Precision Calibration: 6MPa Pneumatic Pressure Calibrator + YW-100B Gauge for Rosemount 3051T Field Calibration

In today’s highly automated industrial environments, pressure transmitters are the “sensory organs” of process control systems. Their performance directly impacts product quality, operational safety, and energy efficiency. The Rosemount 3051T pressure transmitter has become a global standard due to its superior stability, reliability, and HART communication capability.

However, even high-performance transmitters like the 3051T require routine calibration to ensure they continue to deliver precise measurements throughout their lifecycle. In this article, we present a reliable and efficient calibration solution: the 6MPa Pneumatic Pressure Calibrator Pump paired with the YW-100B Explosion-Proof Precision Pressure Gauge.

1. Why Choose the 6MPa Pneumatic Calibrator?

The 6MPa pneumatic pressure calibrator pump is an oil-free, air-driven pressure source, designed for high-precision applications in clean environments.

Key Features:

• Wide Output Range: 0 ~ 6 MPa, suitable for most pressure transmitter ranges

• Oil-Free Operation: Pure pneumatic mechanism avoids oil contamination

• High-Sensitivity Fine Adjustment Valve: Allows precise pressure tuning down to 0.01 MPa

• Stainless Steel Construction: Durable and stable, built for long-term use

• Compact and Portable: Lightweight and easy to carry for on-site calibration work

2.YW-100B – Your Trusted Precision Reference

To ensure accurate pressure readings during calibration, pairing the pump with a reliable reference gauge is essential. The YW-100B stainless steel explosion-proof precision pressure gauge is specifically designed for such demanding applications.

Product Highlights:

• Accuracy Class: 0.05% or 0.02% FS, ideal for metrology-grade calibration

• Material: 304 stainless steel case, corrosion-resistant and explosion-proof

• Stable Readings: Clear dial, anti-vibration design minimizes pointer fluctuation

• Connection Options: M20×1.5 or 1/2NPT threads, compatible with most calibration setups

• Suitable for Harsh Environments: Perfect for petrochemical, power plant, and field maintenance settings

3. Ideal for Calibrating Rosemount 3051T

The Rosemount 3051T is a smart transmitter widely used in applications ranging from tank level measurement to pipeline pressure monitoring. Common features include:

• Output: 4–20 mA with HART protocol

• Range: Up to 40 MPa (varies by model)

• Applications: Steam lines, water treatment, chemical dosing, etc.

Using the 6MPa pneumatic pump with the YW-100B gauge, you can complete:

✓ Zero and Span Point Checks

Compare readings at 0% and 100% of span, and verify output consistency.

✓ Multi-Point Linearity Tests

Verify response at 25%, 50%, and 75% of full-scale pressure.

✓ Smart Adjustment with HART

Use a HART communicator to perform fine-tuning of zero and span under accurate pressure control.
