I. Product Overview

The ACU20P series pressure controller/gauge features a straight-through design with a measurement range from 100 KPa to 10 MPa (both absolute and gauge pressure). Differential pressure transmitters are also available. This series of instruments boasts high accuracy and excellent repeatability, and is available in two types: front pressure control and back pressure control.

The ACU20P series comes standard with a pressure sensor and a digital circuit board, providing high-precision, fast, stable, and reliable pressure control. This PC digital board has all the functions required for pressure control. In addition to the standard RS485 output signal, the ACU20P also provides analog input/output signals, allowing precise control of the entire process by adjusting the setpoint. The ACU20P series pressure controller can be equipped with an integrated control valve or a separate control valve. It is a proportional solenoid valve with ultra-fast and smooth control characteristics.

II. Product Applications

Application areas: Semiconductor processes, gas and liquid chromatography, vapor pressure control in MOCVD processes, gas pressure protection control in extrusion molding processes, high-pressure vessel/reactor pressure control, etc.
