Rail Transit Manufacturing Gains a New Metrology Asset | Shanghai Deyida Introduces Hsin Sheng Weiye HSIN6000T Fully Automatic Pressure Calibration System

Recently, Shanghai Deyida Electronic & Electrical Equipment Co., Ltd. procured the HSIN6000T Fully Automatic Pressure Calibration System from Beijing Hengsheng Weiye, for factory verification and performance calibration of rail transit onboard sensors and pressure instruments, further improving the company's in-house metrological calibration capabilities and solidifying the quality foundation of rail transit equipment products.

Shanghai Deyida is a high-tech enterprise deeply engaged in the rail transit sector, focusing on the R&D and manufacturing of railway signaling, onboard monitoring equipment, speed sensors, and other products. Its products are widely used across multiple domestic rail transit lines, and it maintains stringent requirements for pressure parameter testing of components and complete units. Its metrological testing capability directly affects the operational safety of rail transit equipment. As its business scale continues to expand, the original calibration model suffered from pain points such as cumbersome operation, excessive manual intervention, and low verification efficiency. The company urgently needed a pressure calibration system with a high degree of automation and strong stability to meet the production testing requirements of batch instrument verification and data traceability.

The HSIN6000T Fully Automatic Pressure Calibration System is a fully automatic pressure verification platform developed for industrial laboratories. It is available in micro-pressure, pneumatic, and hydraulic versions, with optional standard pressure modules to suit calibration scenarios involving different ranges and media. Its pressure stability can reach 0.01%F.S/s. The device core adopts a dual closed-loop control scheme for pressure and pressure rate of change, delivering smooth pressure output without overshoot and excellent pressure stabilization performance, in line with the pressure rise/fall and return verification logic requirements of current pressure instrument verification regulations.

The device is equipped with a 7-inch touchscreen, supporting local on-device operation as well as remote control via host computer software. Both modes can fully execute the automatic verification process. The accompanying professional metrology software allows preset verification plans, automatically completing the full process of pressure rise, stabilization, and return pressure drop, automatically collecting pressure, current, and other testing data, and generating original records and verification certificates with one click. It fully preserves testing data, eliminates errors caused by manual reading and handwritten recording, significantly reduces the verification man-hours for batch instruments, and markedly improves laboratory testing capacity.

Once deployed, the equipment will serve Shanghai Deyida's incoming inspection, R&D validation, and factory inspection of rail transit pressure components and onboard instruments, achieving automation of the pressure verification process and complete, traceable retention of testing data. It will provide reliable metrological support for product R&D iteration, component incoming inspection, and finished product factory gatekeeping, helping the company safeguard the quality threshold of rail transit equipment.

This collaboration marks another implementation of Hsin Sheng Weiye's metrology solutions in the rail transit equipment manufacturing industry. The rail transit industry has extremely high requirements for safety and reliability, and high-precision metrology equipment is the underlying guarantee of equipment quality. Hengsheng Weiye continues to serve industries such as rail transit and testing institutions, delivering integrated pressure, temperature, and liquid level metrological calibration equipment and supporting services. With domestically produced high-precision metrology equipment, it helps enterprises across industries improve their internal metrology systems and consolidate the foundation of product quality.

In the future, both parties will continue to maintain technical exchanges, leveraging metrology technology to empower rail transit equipment R&D and manufacturing, and jointly contributing to the high-quality development of the rail transit industry.
