Customer Introduction

A certain experimental instrument company, which develops various high-end experimental equipment and systems for universities, laboratories, and scientific research enterprises. The equipment and systems are mainly used in geotechnical engineering, materials science research, and scientific research teaching.

Operating Conditions Requirements

This experimental instrument company needs to integrate an experimental device for a customer, which requires a gas pressure control function. If a pressure controller is configured, the control pressure must be 15 MPa high pressure, 200 L/min high flow rate, and other partial operating condition requirements are also proposed.

The experimental instrument company stated that they consulted several domestic and foreign measurement and control companies, but none could generally meet these operating condition requirements. The company staff contacted ACCU, hoping to solve this problem.

Solution

The customer clearly only needs a pressure controller, but has not yet found a product that meets the operating conditions on the market. In order to accurately recommend products, ACCU staff communicated in depth with the customer's needs, and learned in detail about the equipment's use, medium, signal output, gas source pressure, and other information. At the same time, they promoted the customer to collect operating condition data and communicated with internal technology.

The customer finally sorted out the operating conditions and conveyed them to ACCU. The basic operating conditions are as follows:
Controlled Medium: Air
Pressure Control Range: 0~10MPa, gauge pressure
Control Ratio: 50:1
Gas Source Pressure: 15MPa
Cavity Volume: 105L
Corresponding Maximum Flow Rate: 200L/min
Signal: 4~20Ma
Communication Method: RS485
Connector: External thread M24*1.5 24° cone

The valve of the pressure controller is a core component, and different valves are configured for different application scenarios. After understanding, the customer also requires the controller to have pressure stabilization and pressure relief functions, and to support high-temperature operating conditions. To achieve this function, a double valve needs to be installed on the pressure regulator, and a split control valve must be used to meet the operating condition requirements.

Because this operating condition is relatively special, ACCU staff proposed a customized solution: based on the general model of ACCU ACU20PCD digital dual-valve pressure controller, add a split control valve, increase the maximum flow rate, and change the connector type, etc.

After completing the solution, the customized product was tested under operating conditions, and the results met the customer's actual needs, and the delivery was successfully completed.

Project Benefits

The customized solution proposed by ACCU staff helped the customer complete the project delivery and achieved good results:

1. Successful high-quality delivery, winning market trust
With the cooperation of ACCU, the experimental instrument company overcame complex operating condition requirements and successfully completed the project delivery with high quality, winning market trust.

2. Shorten delivery time, efficiently complete the project

In this project, ACCU fully demonstrated its customization capabilities and successfully met the demanding operating condition requirements. Through close cooperation and communication, we not only provided customers with satisfactory solutions but also accumulated valuable experience for the company itself.

In the future, ACCU will continue to cultivate the experimental instrument field, using innovative technology, high-quality products, and perfect services to help more customers achieve high-quality development.


Related Products

ACU10FA


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.

ACU10FD


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.

ACU10FDR


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.

ACU10FC


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.

ACU10P


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.
