Do you already know the four major advantages of a sealed container pressure controller?

Word Size
The sealed container pressure controller uses two custom high-speed proportional control valves to rapidly and precisely regulate either absolute or gauge pressure within the closed system. Typically, maintaining a constant pressure inside a sealed container requires the additional installation of an exhaust valve. However, this controller features a unique dual-valve design: one valve maintains the set pressure, while the other serves as a safety relief valve, eliminating the need for an extra exhaust valve and significantly reducing waste of expensive gases. Additionally, the sealed container pressure controller can effectively manage and maintain the pressure differential within the container.
Advantages of using a sealed container pressure controller:
1. Repeatability:
Typically, process equipment with a modular design requires instruments that are highly repeatable. This product boasts remarkable repeatability: ≤0.1%.
2. Response Speed:
Through improved PID loop control, the closed-container pressure controller can quickly and accurately reach a setpoint. Since the PCD utilizes control calculations similar to those of the PC single-valve series, its response time is measured at less than 0.1 second.
3. Reduce Costs:
The sealed container pressure controller allows only one valve to remain open at a time, automatically switching the PID loop control to the corresponding valve. By simultaneously opening and closing a single valve, it significantly reduces gas emissions required to maintain a set pressure—effectively minimizing gas waste. Switching to this pressure controller can help users who purchase bottled gases save thousands of dollars in costs each year.
4. Control Precision:
This product employs an advanced PID control loop and two proportional control valves, enabling standard control accuracy as low as ≤±0.5% F.S., with higher-precision options available upon request. The enhanced PID loop and proportional control mode not only improve the precision of pressure regulation in sealed or nearly sealed systems but also eliminate the blind spots inherent in pressure controllers that rely on pressure switches or on/off valves.
Currently, closed-container pressure controllers are widely used across various industry sectors, including leak testing, fuel cells, fluid dispensing, and process control. Featuring a 1:100 adjustable range, they deliver precision as high as ≤±0.5% F.S., with repeatability better than ≤0.1%, and a control response time of less than 100 milliseconds—features that significantly optimize the pressure control process.
Technical features:
1. The sealed container pressure controller is suitable for various industrial applications and can ideally replace similar foreign products.
2. Stable performance, simple structure, and no detachable components;
3. Multiple pressure and electrical interfaces available for selection.
The ACU10FA analog-type mass flow controller features fast response and high precision. It offers a wide control range, with a flow rate capability spanning from 5 SCCM to 30 SLM, and can accurately measure and regulate flows as low as 1 SCCM—making it ideal for controlling even the tiniest gas flows.
The ACU10FD digital mass flow controller consists of a mass flow sensor, laminar flow separator, flow controller regulating valve, and amplification control circuit. It features digital signal input and output, offering advantages such as short preheating time, minimal zero drift, and high reliability.
The ACU10FDR low-pressure-drop gas mass flow controller is equipped with a proprietary high-flow electromagnetic valve, making it ideal for controlling mass flow even when system pressure is nearly unavailable. Its minimal pressure differential ensures the least possible impact on the system, enabling precise flow control under near-atmospheric conditions while significantly reducing system response time. We can customize the valve and PID control features based on your specific application parameters, guaranteeing fast, stable performance with minimized pressure loss.
The ACU10FC differential-pressure mass flow controller employs a differential-pressure-based mass measurement principle that features no thermal drift and zero response lag. It can simultaneously display and output parameters such as instantaneous flow rate, totalized flow, pressure, and temperature. When control functionality is required, an electromagnetic proportional control valve can be added, along with built-in PID regulation capabilities.
Unlike thermal mass flow meters, the ACU10FC eliminates any additional "specific heat capacity" error when using gas conversion factors. As a result, even if the gas being measured differs from the calibration gas used at the factory, the measurement accuracy remains unaffected.
The ACU10P series pressure controllers/pressure gauges feature a straight-through design, with measurement ranges from 100 kPa to 10 MPa (both absolute and gauge pressures are supported). Additionally, differential pressure transmitters are also available.
