offering rapid stable pressure regulation through precise pilot valve control

Product Specification

Series Core Advantages and Features
1. Advanced Servo Pressure Control Technology
Utilizes imported high-precision servo pressure regulating valves. Precise control of main valve actions via pilot valves enables rapid, stable pressure regulation without overshoot.
Eliminates the stepwise pressure changes inherent in traditional on/off valves, delivering smooth, continuous pressure control that significantly enhances calibration efficiency and accuracy.
2. High Integration and Modularity
Integrated Design: Combines vacuum, pneumatic, and hydraulic functions in a single unit for broad coverage.
Modular Pressure Modules: Standard configuration includes multiple SDP modular smart digital pressure calibrators. Utilizes imported high-precision sensors with excellent long-term stability, wide measurement range, and independent operation capability.
Modular Pressure Interfaces: Multiple M20×1.5 standard female threaded ports enable simultaneous calibration of multiple instruments.
3. Intelligence and Automation
Fully Automatic Pressurization: Built-in dynamic balancing technology ensures instantaneous pressure stabilization without leakage.
Integrated HART Handheld Communicator: Enables direct management of basic information, range migration, zero point, and temperature calibration for HART smart transmitters without additional equipment.
Robust Communication Capabilities: Interfaces with host computer software for automated data acquisition, processing, storage, and result printing, facilitating quality management.
4. Flexible Multi-Function Display
Equipped with multiple independent standard display meters, simultaneously showing real-time parameters like pressure, current, and voltage for intuitive monitoring.
High-resolution touchscreen provides an intuitive human-machine interface with Chinese display support for simplified operation.
