Fully Automatic Pressure Verification Equipment: One-Button Fully Automatic Pressure Instrument Calibration System
Nexisense Fully Automatic Pressure Verification Equipment is an intelligent pressure instrument calibration platform that truly realizes “one-button” operation. Users only need to select the range of the instrument under test and press the “Start” button. The system will automatically complete the entire process of pressurization, depressurization, pressure stabilization, data acquisition, error calculation, report generation, and certificate printing, completely freeing the hands of verification personnel and greatly improving verification efficiency and data consistency.
Product Overview
The equipment is available in two models: hydraulic type (XY-ZQ681) and pneumatic type (XY-ZQ860). It adopts high-precision pressure modules and an intelligent control system, with built-in or external pressure sensors. Accuracy class is optional at 0.02 or 0.05 grade. The system fully complies with Chinese pressure instrument verification regulations and does not rely on high-pressure gas cylinders to provide a stable pressure source. It is suitable for laboratory standard verification and batch field calibration in production.
A single dual-channel fully automatic pressure calibration bench can easily allow one person to verify more than 56 pressure instruments per day, significantly reducing labor costs. It is the ideal equipment for pressure instrument quality control in metering verification institutions, instrument manufacturing enterprises, and engineering companies.

Selection Guide and Integration Notes
Selection Key Points
Hydraulic type (XY-ZQ681) is suitable for high-pressure range verification from 0～60 MPa; pneumatic type (XY-ZQ860) is suitable for micro-pressure and medium-low pressure ranges.
For occasions with high precision requirements, prioritize the 0.02 grade pressure module.
Projects requiring full-process software management are recommended to be used with automatic verification software.
For batch verification projects, contact Nexisense for OEM customization, including number of channels, software functions, and interface optimization.
Integration Notes
Before use, confirm that the working medium is clean to avoid impurities entering the system.
During high-pressure verification, strictly follow operating procedures and pay attention to the overpressure protection function.
When connecting to host computer software, ensure communication interface matching and perform necessary parameter settings.
Regularly check the status of pressure interface seals and keep the equipment clean and dry.
Before restarting after long-term shutdown, it is recommended to perform zero-point calibration.
Nexisense supports OEM/ODM customization and bulk supply of fully automatic pressure verification equipment. We can provide complete system solutions according to users’ verification regulations, instrument types, and software requirements.
FAQ
Q1. What are the main advantages of the fully automatic pressure verification equipment compared to traditional manual calibration benches?
It realizes true one-button automatic verification, automatically completing pressurization, pressure stabilization, data recording, error analysis, and report printing. Single-person daily verification capacity can reach more than 56 units, with efficiency and consistency far higher than manual operation.
Q2. Does this equipment require an external high-pressure gas source?
No external high-pressure gas cylinder is required. The hydraulic type uses transformer oil or purified water, and the pneumatic type uses air to provide a stable pressure source.
Q3. Which instruments does it support for verification?
It can verify pressure transmitters, pressure switches (pressure controllers), ordinary pressure gauges, precision pressure gauges, and other pressure instruments.
Q4. What is the pressure stabilization accuracy and verification time?
Pressure stabilization accuracy is controlled within 5 digits. The full 9-point verification for transmitters takes about 5 minutes, and pressure switch verification takes about 2 minutes.
Q5. Does it support overpressure protection?
It has comprehensive safety protection functions. When exceeding 110% of the range, it automatically alarms and stops pressurization. It also has multiple protections including overcurrent, leakage, and sensor failure.
Q6. Can it be connected to automatic verification software?
