High Accuracy, Fast Pressurization, and Long-Term Stability — All in One Instrument

The MC300 Pressure Controller incorporates Yokogawa's proprietary silicon resonant sensor and a needle valve servo mechanism to deliver high-accuracy pressure control. With an output relative accuracy of ±0.04% and a 12-month accuracy guarantee period, it provides stable pressure control over extended operating periods. The MC300 is used across a wide range of process management and production automation applications that require precise pressure control, including production line inspection of pressure sensors and pneumatic devices, compliance testing of blood pressure monitors, leak testing of enclosures, and calibration of differential pressure and pressure transmitters.

High-accuracy pressure control that suppresses variation in starting pressure and supports highly repeatable air leak testing

A pressure controller can stably generate the starting pressure in air leak testing for automotive parts such as inverters and battery cases. By suppressing variation in the starting pressure, highly repeatable testing can be expected throughout the entire process, from development to mass-production final inspections.

Continuous control with a needle valve mechanism shortens takt time in mass-production pressure sensor inspection

A needle-valve pressure controller can be used for final inspection of pressure sensors on mass-production lines in the automotive, industrial equipment, and medical device industries. By combining high-speed pressurization with low overshoot, it can help shorten inspection takt time, streamline pressurization and depressurization testing, and support long-term stable operation.
