一、 Industry dilemma under import capacitor vibration chip tariff crisis

In recent years, the United States' policy of imposing tariffs on China has led to a significant increase in the cost of capacitive acceleration sensors, mainly imported from the United States. The prices of some core models have risen by as much as 30% -50%, and the delivery cycle has been extended, resulting in a sharp decline in supply chain stability. This change has a serious impact on the domestic wireless intelligent vibration monitoring industry that relies on such sensors:

-Cost pressure: In the fields of industrial Internet of Things, wind power, rail transit, etc., customer procurement costs have surged, and project profit margins have been compressed;

-Supply risk: Uncertainty in international logistics and trade policies threatens the continuity of enterprise production;

-Passive technology: Key components are controlled by others, which restricts the process of domestic high-end equipment localization.

二、 Domestic solution of Senther Technology: Breakthrough advantages of 540A/540C piezoelectric sensors

As a leading enterprise in piezoelectric sensing technology in China, Senther Technology has launched the 540C (standard industrial grade) and 540A (high-frequency precision type) series acceleration sensors, which provide a cost-effective alternative path for the industry with a 100% domestically produced supply chain and benchmark international performance parameters

1. Core performance benchmarking, seamless replacement of imported capacitive accelerometers solution

-Broadband high sensitivity: The 540C series has a bandwidth of 0.5-28000Hz @ ± 3dB, 1-14000Hz @ ± 10%, and can be selected from two models: ± 50g sensitivity 40mV/g and ± 500 sensitivity 4mV/g. It has an industrial grade appearance similar to imported capacitor acceleration products, but its performance indicators are much higher than capacitor chip products, making it particularly suitable for existing vibration monitoring systems;

-Extreme environmental adaptability: operating temperature range of -40 ℃~150 ℃, using long-term stable and reliable shear ceramic technology to meet the long-term stable monitoring needs of harsh working conditions such as petroleum, petrochemicals, wind power, mining machines, etc;

-Low power design: Designed with a current consumption of less than 1mA, compatible with the low-power requirements of wireless vibration monitoring nodes;

-Ultra low noise design: 4 µ g/√ Hz @ 1kHz

-Installation support: Z-axis measurement perpendicular to the installation surface, and the entire line supports reflow soldering operation process requirements (with the "540C&590C Piezoelectric Acceleration Sensor High Temperature Reflow Soldering Operation Guidance Document" attached)

2. Core value of localization

-Zero tariff cost advantage: Local production avoids an additional 25% tariff, resulting in a comprehensive cost reduction of over 40% compared to imported capacitor accelerometers of the same level;

-Agile supply chain response: The Yangtze River Delta and Pearl River Delta supply chain clusters ensure a 7-day delivery cycle and support urgent customer order needs;

-Customized service capability: Provide parameter customization such as sensitivity and interface protocol, and quickly match customer PCB designs.

3. Technological autonomy and controllability

-Core technology of piezoelectric ceramics: doped modified PZT material with stable annular shear structure, which has better long-term stability than capacitive sensors;

-Fully automated calibration: Achieving ± 1% batch consistency through laser fine-tuning technology to ensure industrial grade reliability.

三、 Alternative Implementation Path: How to Smoothly Transfer to Senther Sensor

1. Hardware compatibility design

-Pin compatibility: The 540A series provides the same 3.3V/5V power supply interface as imported capacitive accelerometers, which can directly replace the original sensor module;

-Signal conditioning adaptation: Provide supporting signal amplification/filtering reference designs to address the differences in output characteristics between piezoelectric sensors and capacitive sensors.

2. Data consistency assurance

-Cross validation database: Senther has established a comparison database between mainstream models of imported capacitive accelerometers and 540A/540C operating condition data, allowing customers to quickly verify the compatibility of monitoring algorithms;

-OEM collaboration support: open the sensor raw data interface to help customers optimize the filtering algorithm of edge computing nodes.

3. Full lifecycle services

-Old model replacement subsidy: Provide technical guidance and cost subsidies for 1:1 replacement of existing imported capacitor accelerometer projects;

-Joint R&D Program: Collaborate with leading clients to establish a vibration diagnosis model optimization laboratory, accelerating the deep adaptation of domestic sensors and AI algorithms.

四、 Industry Win win: Building a Domestic Sensor Ecological Chain

-Senther Technology Industry Chain Partner, creating a full stack domestic vibration monitoring solution from sensor chips to cloud analysis. At present, the 540 series has been successfully applied to:

-Wind power operation and maintenance: A state-owned enterprise's wind farm project replaced over 2000 imported capacitive accelerometer sensors, saving over 6 million yuan in annual procurement costs;

-Intelligent Machine Tool: Replace the vibration module of imported acceleration chip companies to achieve closed-loop control of CNC system vibration compensation;

-Urban pipe gallery: Implement 50km wireless vibration network deployment in underground pipe network equipment monitoring;

-Petrochemical: Batch application of wireless intrinsic safety intelligent vibration sensors to assist in the intelligent upgrading and transformation of tens of thousands of old energy production equipment.

Finally, tariff barriers force supply chain autonomy, and the Senther Technology 540A/540C series, with the dual value of "uncompromising performance and better cost", helps customers take the initiative in the turbulent international trade environment. We call on the industry to jointly promote the localization and substitution of high-end sensors, so that China's intelligent manufacturing is no longer constrained by "chips".
