Xi'an Shenghongchuang Instrumentation Co., Ltd. Successfully Solves Flow Control Challenges Under Complex Operating Conditions

Leveraging the outstanding performance of the CY-DB2104 differential pressure transmitter, Xi'an Shenghongchuang Instrumentation Co., Ltd. successfully helped a customer in Xi'an solve flow control challenges under complex operating conditions. As a professional differential pressure sensor manufacturer, we provide a full range of customizable differential pressure transmitters such as PTS801 and DMP338, winning the trust of industrial customers with precise measurement and stable performance.

1. Flow Control Challenges Faced by the Customer

On the production line of a large chemical enterprise in Xi'an, the customer encountered difficult flow control problems. Due to the complex characteristics of the medium (high viscosity, containing particulates) and large pipeline pressure fluctuations (±0.5MPa), the conventional DMP335 differential pressure transmitter frequently experienced measurement drift, resulting in:

• Process parameter control deviation reached 8%, exceeding the allowable range
• Monthly raw material waste caused by this exceeded 3万元
• Equipment maintenance frequency increased to once per week

After an on-site inspection, our engineers found that the diaphragm material (316L stainless steel) of the existing transmitter could not adapt to the corrosiveness of the medium, and the traditional sensor structure was prone to blockage by particulates.

2. Customized Solution of the CY-DB2104 Differential Pressure Transmitter

In view of the characteristics of these operating conditions, we recommended the CY-DB2104 differential pressure transmitter with a modular design and carried out three key improvements:

At the same time, this solution retains the core advantages of the CY-DB2104: 0.05% high accuracy, IP68 protection rating, and support for HART/Modbus dual-protocol communication.

3. Implementation Results and Customer Benefits

Tracking data after three months of operation showed:

1. Measurement stability: fluctuation amplitude decreased from ±8% to ±0.3%, better than the GB/T 17614-2015 standard
2. Economic benefits: annual raw material loss savings reached 36万元, maintenance costs reduced by 67%
3. Expanded application: the customer subsequently purchased an additional 12 transmitters of the same model

The successful implementation of this case also prompted us to carry out process upgrades to the same standard for other product series such as PTS801 and ZFBY3083T.

4. Differential Pressure Transmitter Selection Guide

Based on 20 years of industry experience, we have summarized the key selection factors:

• Medium characteristics: for corrosive media, priority should be given to the YM-7 series with PTFE lining
• Pressure range: DS6100 is suitable for 0-10kPa micro-pressure measurement, and BYP610 is suitable for 10MPa high pressure
• Output requirements: LDN100 provides dual signals of 4-20mA+pulse output
• Certification requirements: SP-832 has passed SIL2 certification and is suitable for safety-critical applications

All models can provide special versions such as explosion-proof and intrinsically safe, and support non-standard customization services.

5. Why Choose Xi'an Shenghongchuang
