I. Product Overview

The CWKJ200/100 model pressure automatic control device is a single-channel/multi-range automatic pressure controller, utilizing modern high-precision pressure sensor technology with an accuracy of up to 0.01%FS. It offers high measurement precision and long-term stability, making it particularly suitable as a production tool for transmitter manufacturing, a calibration and maintenance tool for pressure measuring instruments, and as a factory/work standard for calibrating various pressure measuring instruments. It is designed for automatic and semi-automatic verification and calibration of overpressure and absolute pressure measuring instruments (such as pressure calibrators, sensors, reference, and technical pressure gauges), with a measurement range of 0~100MPa.
