Automatic Piston Pressure Calibrator

Product detail

Product Introduction

The IQS910-X Fully Automatic Piston Pressure Calibratorseries includes four models:

  • IQS910P — Fully Automatic Gas Piston Pressure Gauge

  • IQS910H — Fully Automatic Liquid Piston Pressure Gauge

  • IQS910A — Fully Automatic Absolute Pressure Piston Gauge

  • IQS910N — Fully Automatic Positive/Negative Pressure Piston Gauge

The system consists of a fully automatic piston pressure gauge main unit and a pressure controller, enabling fully automatic weight loading and pressure generation. The structure and materials are designed for wear resistance, ensuring that the maximum error of the piston system remains within permissible limits throughout a verification cycle.
It is suitable for industries including metrology institutes / bureaus, electric power, nuclear power, high-speed rail, metallurgy, petroleum, chemical, power construction, petrochemical construction, military, aviation, aerospace, shipbuilding, aircraft maintenance, gas fields, oil fields, third-party testing institutions, higher education institutions (teaching), factories, mines and enterprises, and pressure instrument manufacturers. It provides highly stable and accurate pressure calibration instruments for pressure instrument verification, calibration, teaching and research, improving pressure verification efficiency.

Key Features

  • Fully automatic weight loading

  • Built-in pressure source for fully automatic pressure generation

  • 24 V output and electrical signal measurement functions

  • Real-time measurement of piston position and piston head temperature

  • Real-time measurement of weight rotation speed

  • Synchronous rotation of all weights — zero wear during weight loading

Main Functions

  • Fully automatic verification of pressure transmitters— automatic recording of verification results, automatic printing of verification reports

  • Fully automatic verification of precision digital pressure gauges— automatic recording of verification results, automatic printing of verification reports

  • Fully automatic verification of pressure indicating gauges— automatic error calculation, automatic recording of verification results, automatic printing of verification reports
