In the field of industrial fluid control, the MICO-M pressure transmitter has become an ideal choice for liquid and gas pressure measurement by virtue of its core diffused silicon sensor technology. This article will provide an in-depth analysis of its 5 core advantages, including high accuracy, long-term stability, corrosion resistance, temperature adaptability, and cost performance, helping engineering procurement personnel quickly match project requirements. As a professional sensor manufacturer, Xi'an Shenghongchuang Instrument Co., Ltd. provides a full range of genuine pressure transmitter solutions from LED-LED131 to TSZ-P.

Technical Definition and Market Positioning of Diffused Silicon Sensors

As the core component of the MICO-M series, the diffused silicon pressure sensor adopts the piezoresistive effect principle of semiconductor silicon materials, and forms a Wheatstone bridge on the silicon diaphragm through ion implantation technology. Compared with traditional strain gauge sensors, its sensitivity is increased by more than 30%, and temperature drift is controlled within the range of ±0.02%FS/℃. In the current industrial sensor market, diffused silicon technology has accounted for 42% of the share in the liquid and gas measurement field (according to the 2023 Global Industrial Sensor White Paper), and is especially suitable for industries such as petrochemicals, water treatment, food, and pharmaceuticals that have stringent requirements for measurement stability.

Technical Performance Analysis of 5 Core Advantages

1. 0.1%FS High-Accuracy Measurement

The MICO-M pressure transmitter performs full-temperature-range compensation of sensor signals through an ASIC chip, maintaining an accuracy class of ±0.1% within the operating range of -20℃~85℃. Measured data show that in natural gas pipeline pressure monitoring scenarios, the standard deviation of its continuous 30-day measurement data is only 0.008MPa, which is significantly better than the industry average level of 0.25%FS for traditional ceramic capacitive sensors.

2. 5-Year Long-Term Stability Assurance

Using military-grade silicone oil filling technology and a 316L stainless steel isolation diaphragm, the product still maintains its initial accuracy after passing 1 million pressure cycle tests. Models such as HB-HB451 provided by Xi'an Shenghongchuang have been in continuous operation for 58 months at a refinery of Sinopec in China, with an annual drift of less than 0.05%, greatly reducing calibration and maintenance costs.

3. Corrosion-Resistant Solutions for Special Media

For highly corrosive media such as hydrochloric acid and chlorine gas, the AO-P-310 model with an optional Hastelloy C276 diaphragm is available, and its corrosion resistance performance has reached the Class A requirements of the ASTM G48 standard through third-party testing. A case from an aluminum electrolysis plant shows that in an environment containing HF gas, its service life is 3.7 times that of ordinary 304 stainless steel sensors.

Procurement Selection Guide and Cost Analysis

When selecting a diffused silicon liquid and gas pressure sensor, contract executors need to focus on matching the following parameters: measurement range (it is recommended to select 1.5 times the upper limit of the range), process connection method (G1/2" or flange), and output signal (4-20mA/RS485). Models such as SSI-P51 provided by Xi'an Shenghongchuang support customized tiered quotations, and bulk purchases of more than 100 units can enjoy a 15% discount, saving 40% of the procurement budget compared with the imported brand RD-RD131 series.
