SongFast Technology Launches the Industry's First Temperature-Compensated Piezoresistive Pressure Sensor Core

2025-05-11

Ceramic materials are widely recognized for their high elasticity, corrosion resistance, wear resistance, and ability to withstand impact and vibration. Ceramic pressure sensors, which utilize a ceramic diaphragm as the sensing material, are the second most commonly used type after MEMS pressure sensors in pressure measurement applications. Their advantages—such as corrosion resistance, elimination of the need for oil filling, and high-temperature stability—make them ideal for automotive and industrial electronics, including engine systems, HVAC systems, diesel urea tanks, and industrial refrigeration systems. The annual domestic demand for these sensors is approximately tens of millions of units. Among them, ceramic piezoresistive pressure sensors are preferred for IoT applications due to their high cost-effectiveness.

After several months of research and product optimization, Dongguan SongFast Technology has launched the industry’s first temperature-compensated piezoresistive pressure sensor core, filling a domestic gap and achieving world-class performance.


CPS18 Series Ceramic Pressure Sensors

The CPS18 series ceramic pressure sensors produced by SongFast Technology are crafted using precision alumina ceramic substrates, advanced thick-film microelectronics technology, and high-stability sensitive materials. The manufacturing process involves advanced techniques such as screen printing, high-temperature sintering, and laser trimming.

The newly released CPS18 series incorporates unique circuit and pattern designs, employing laser inline active temperature compensation. In typical usage scenarios, the influence of temperature fluctuations on the sensor is nearly negligible. This innovation significantly reduces the workload during large-scale sensor calibration and greatly enhances the product's reliability.


Unique Advantages

The corrosion resistance, "dry" packaging, and high-temperature stability of ceramic pressure sensors provide them with distinct advantages in fields such as refrigeration, chemicals, pharmaceuticals, and environmental protection. As a result, they are gradually replacing conventional pressure sensors like diffused silicon. We also offer customization of ceramic pressure sensor cores in various shapes and sizes according to customer requirements. We welcome your inquiries.


Perceiving the World, Innovating the Future

Our company is dedicated to the development, design, and production of ceramic pressure sensor cores and transmitters. We provide comprehensive pressure sensor solutions for industries such as automotive, air conditioning, industrial control, and aerospace. Our goal is to break the monopoly and core technology blockade imposed by international giants on ceramic pressure sensor cores in China, achieving import substitution for these critical components.
