2024 Diffused Silicon Pressure Transmitter Selection Guide

In the field of industrial automation, the selection of pressure transmitters directly affects production efficiency and equipment safety. As a core component of flow control equipment, the PA-PY series pressure transmitters have become the preferred choice of many enterprises due to their stable performance and excellent cost-effectiveness. This article provides an in-depth analysis of the mainstream diffused silicon liquid and gas pressure sensors on the market in 2024, helping you find a solution that is both economical and reliable.

I. Core Advantages of Diffused Silicon Pressure Sensors

As a mainstream solution in the field of pressure sensing, diffused silicon technology has significant advantages over traditional strain gauge sensors. It uses semiconductor technology to form a Wheatstone bridge by diffusion on a silicon chip, with sensitivity 50-100 times that of metal strain gauges and more stable temperature characteristics. Products such as the PA-Y and PA-Ei series manufactured by Xi'an Shenghongchuang Instrumentation Co., Ltd. all use imported diffused silicon chips, with long-term stability up to ±0.1%FS/year, making them particularly suitable for harsh operating conditions such as petrochemicals and water treatment.

In practical applications, diffused silicon sensors demonstrate three core values:

• Accuracy Assurance: High-end models such as PTS-PTS702 can achieve 0.075% accuracy, meeting ISO9001 certification requirements
• Cost Advantage: The factory-direct supply model makes models such as PA-SEi priced 15-20% lower than the market average
• Strong Compatibility: The HP-1 series supports multiple protocol outputs such as HART and Modbus, adapting to various PLC systems

II. Comparative Analysis of Mainstream Model Performance

According to third-party testing data in 2024, we conducted a horizontal evaluation of six popular diffused silicon pressure transmitters on the market:

Of particular note is the PTS-PTS612 model, which adopts military-grade ceramic capacitive technology and performs excellently in the food and pharmaceutical industries. For corrosive media, the PA-Ei series is equipped with a Hastelloy diaphragm, with a service life more than 3 times that of ordinary models.

III. Five Key Indicators for Selection

1.Media Compatibility: For gas measurement, the PA-Y series with built-in temperature compensation is recommended; for liquid measurement, priority should be given to the PTS702 with a 316L isolation diaphragm

2.Environmental Adaptability: For outdoor applications, attention should be paid to the IP protection rating; the PM-PR series reaches IP68 and can be used underwater

3.Long-Term Stability: The annual drift of high-quality diffused silicon sensors should be ＜±0.1%; Xi'an Shenghongchuang products are verified through 1000-hour aging tests

4.Certification Standards: The petrochemical industry requires ATEX explosion-proof certification, while the food industry requires 3A sanitary certification

5.After-Sales Service: Regular manufacturers should provide an 18-month warranty; for example, the PTS614 series enjoys free calibration services

IV. Cost Optimization Strategies for Factory-Direct Supply

As a leading sensor manufacturer in Northwest China, Xi'an Shenghongchuang reduces production costs by 30% through vertically integrated supply chains. For different procurement needs, we provide tiered quotation plans:

• Sample procurement: Standard models such as PTS612 support orders starting from 1 unit
• Small and medium batches: Orders of 50 units or more of the PA-SEi series enjoy a 10% discount
• Annual agreement: Signing a framework contract entitles you to free technical training

Special reminder: Orders for the HP-1 series before Q3 2024 can be upgraded to the Modbus-RTU communication protocol free of charge. Bulk purchases of PA-PY pressure transmitters can also enjoy complimentary accessory packages such as installation brackets.

V. Analysis of Industry Application Scenarios

In the smart water sector, the PTS-Z series, with its hygienic design, has been successfully applied in a secondary water supply project in a provincial capital city, where more than 2000 units have operated for 3 years with zero failures. In oil and gas transmission scenarios, the PA-Ei explosion-proof pressure transmitter has withstood the extreme environment of Xinjiang oilfields, with measurement deviation consistently maintained within 0.3%.

For the food and beverage industry, we recommend the PTS-PTS702 stainless steel all-welded structure, which is EHEDG certified and can withstand CIP/SIP cleaning processes. For the wind power industry, the PM-PR series wide-temperature products are more suitable, maintaining stable output even at -40℃.
