I. Product Overview

The ACU10P series pressure controllers/pressure gauges feature a straight-through design and cover a measurement range from 100 kPa to 10 MPa (both absolute and gauge pressures are supported). In addition, differential pressure transmitters are also available. This series of instruments boasts high accuracy and excellent repeatability, and is available in two configurations: front-pressure control and back-pressure control.

The ACU10P series comes standard with a piezoelectric diaphragm pressure sensor and a digital circuit board, offering high-precision, stable, and reliable pressure measurement and control. This basic digital PC board features all the essential functions required for measurement and control. In addition to being equipped with a standard RS485 output signal, the ACU10P also provides analog I/O signals.

II. Product Applications

The ACU10P pressure controller can be equipped with either an integrated control valve or a split-type control valve. It is a proportional solenoid-controlled valve characterized by ultra-fast and smooth control performance. We offer various series of control valves tailored to specific application fields. For conventional applications, a standard direct-acting valve is used; for high-flow-rate applications, a pilot-operated valve is recommended. Application areas include: semiconductor processes, gas-phase and liquid-phase chromatographs, vapor-pressure control in MOCVD processes, gas-pressure protection control during extrusion molding, and pressure control in autoclaves/reactors, among others.
