I. Product Overview

The ACU10P series pressure controllers and pressure gauges feature a straight‑through design, with measurement ranges from 100 kPa to 10 MPa—available in both absolute and gauge pressure configurations. In addition, differential pressure transmitters are also offered. This series delivers high accuracy and excellent repeatability, and is available in two configurations: upstream pressure control and downstream pressure control.

The ACU10P series comes standard with a piezoelectric diaphragm‑type pressure sensor and a digital circuit board, delivering high‑accuracy, stable, and reliable pressure measurement and control. This basic digital PC board incorporates all the essential functions required for measurement and control. In addition to the standard RS485 output signal, the ACU10P also offers analog I/O signals.

II. Product Applications

The ACU10P pressure controller can be equipped with either an integral or a modular control valve. It features a proportional solenoid‑controlled valve that delivers exceptionally fast and smooth regulation. We offer a range of control valves tailored to specific application areas: standard direct‑acting valves for routine use, and pilot‑operated valves for high‑flow applications. Typical applications include semiconductor processing, gas‑phase and liquid‑phase chromatography, vapor‑pressure control in MOCVD processes, gas‑pressure protection during extrusion molding, and pressure control in autoclaves and reactors, among others.
