What is the secret behind the FY-FY211 pressure transmitter's 30% accuracy improvement? The diffused silicon Wheatstone bridge core technology is the key! As a professional supplier in the field of flow control equipment, Xi'an Shenghongchuang Instrumentation Co., Ltd. reveals the core technical advantages of FY-FY212, DMP-DMP335 and other series products for you, helping business evaluators accurately select high-precision, long-life pressure sensor solutions.

Diffused silicon Wheatstone bridge technology: a revolutionary breakthrough in accuracy and service life

In the field of flow control equipment, the accuracy of pressure transmitters directly affects system stability. The diffused silicon Wheatstone bridge technology adopted by Xi'an Shenghongchuang Instrumentation Co., Ltd. realizes micro-strain detection through the piezoresistive effect of monocrystalline silicon materials, improving the overall accuracy of FY-FY211 and other series products to ±0.075%FS, which is 30% higher than traditional products. This technology forms a Wheatstone bridge on the surface of the silicon chip through semiconductor processing. When pressure is applied, the resistance value change of the bridge arm has a linear relationship with pressure. Combined with a temperature compensation algorithm, it ensures that temperature drift within the range of -20℃~85℃ is ≤±0.01%/℃.

Comparative analysis of key performance parameters

In-depth analysis of industry application scenarios

In the petrochemical field, the PMP131-A1B01A73 pressure transmitter combined with a diffused silicon Wheatstone bridge sensor can withstand H2S corrosive environments; in smart water systems, the DMK-DMK457 series achieves long-term monitoring at a depth of 5 meters underwater through an IP68 protection design. It is particularly worth noting that, similar to the domestic weighing sensor LCS-M4 miniature weighing sensor load pressure button-type pressure sensor, our pressure transmitters also perform excellently in the electronic scale field, and their overall accuracy of 0.02~0.03 meets trade settlement-grade requirements.

Procurement selection guide: avoid three common misunderstandings

1. Misunderstanding 1: excessively pursuing measuring range. In practice, products with a turndown ratio of 10:1 should be selected. For example, the 8472.25-5717 transmitter can maintain optimal linearity within the 0~10MPa range
2. Misunderstanding 2: ignoring media compatibility. For acidic and alkaline media, a 316L stainless steel isolation diaphragm must be selected
3. Misunderstanding 3: overlooking certification requirements. Export equipment must comply with the EN 837-1 standard, and the 18.601G-G series has passed ATEX explosion-proof certification

Why choose Xi'an Shenghongchuang?

As a national high-tech enterprise in Xixian New Area, we have a complete pressure sensor industry chain: from the independent R&D of diffused silicon chips to the fully automated production of transmitters, the 30.600G-G series products have been successfully applied in key national projects such as West-to-East Gas Transmission. To address the cost issue most concerned by business evaluators, we provide the PTHY-A technical evaluation report template to help you accurately calculate TCO（total cost of ownership）.

Outlook on technological development trends

With the development of IIoT, future pressure transmitters will evolve toward intelligence. The YM-110 series has integrated the HART7.0 protocol, supporting remote diagnostics and parameter configuration. In the materials field, the development of silicon carbide sensors will raise the upper operating temperature limit to 300℃, which will completely transform pressure measurement methods under high-temperature working conditions.
