Features of Instrumentation
±1% Full-Scale High Accuracy
Instrumentation utilizes high-stability sensing elements to limit errors within 1%, ensuring precise data to prevent blowouts or equipment damage from false readings.
Corrosion Resistance
Constructed from 316L stainless steel with a precision piston rod, Instrumentation resists saline and acidic fluids, extending service life to 5–8 years in harsh environments.
Silicone Oil-Filled, Vibration-Dampening Structure
The instrumentation utilizes a high-viscosity silicone oil filling, supplemented by an adjustable damper, capable of absorbing over 90% of mechanical vibrations and pressure pulses to ensure stable and clear readings under conditions of severe vibration.
Broad Compatibility
Compatible with various types of mud pumps, fracturing trucks, and power tongs; interface standards cover globally recognized thread types such as NPT, G, and BSP.
Versatile Application
Specifically designed for use with crude oil, natural gas, cement slurries, and high-pressure steam, making it suitable for deployment across the entire petrochemical industry value chain.
Quality Control
Spectral Composition Analysis
Every batch of steel material undergoes verification using a handheld PMI spectrometer to confirm the content of corrosion-resistant elements—such as nickel and chromium—ensuring full compliance with the 316L material standard.
Precision Thread Gauging
Each connection thread is individually inspected using GO/NO-GO plug gauges to guarantee a 100% perfect fit with capsules or pipelines during field installation.
1.5x Overpressure Seal Testing
Instrumentation units are subjected to a static pressure hold at 150% of their rated pressure for two hours to ensure the housing remains completely free of even the slightest leaks.
Five-Point Linear Calibration
Every instrument undergoes calibration checks at 0%, 25%, 50%, 75%, and 100% of its full scale; any unit failing to meet the specified tolerance limits is immediately rejected.
24-Hour Simulated Operational Aging
25-Finished products are placed on a high-frequency vibration table and subjected to continuous operation for 24 hours to eliminate any potential mechanical or structural vulnerabilities.
