High-Sensitivity And High-Output Piezoresistive Pressure Transmitter
Features and Advantages
Extremely High Precision and Stability:
Modern piezoresistive sensors can achieve ±0.075% or even higher accuracy.
They have low long-term drift and good repeatability, making them the cornerstone of high-performance industrial applications.
Excellent Frequency Response:
The silicon diaphragm is highly rigid and lightweight, providing extremely fast dynamic response, which is suitable for measuring rapidly changing pressures, including pulsating and shock pressures.
High Sensitivity and High Output:
The piezoresistive effect is significant, resulting in a strong raw signal (mV/V), which is beneficial for signal processing and improving the signal-to-noise ratio.
Miniaturization and Low Cost:
Thanks to mature MEMS (Micro-Electro-Mechanical Systems) manufacturing technology, piezoresistive silicon chips can be made very small and produced in large quantities at a very low cost. This makes the technology applicable in a wide range of devices, from industrial transmitters to automotive sensors and barometers in smartphones.
Wide Measurement Range:
By designing silicon diaphragms of different thicknesses and structures, sensors can be manufactured to measure pressures ranging from a few centimeters of water column for micro-pressure to hundreds of megapascals for ultra-high pressure.
Typical application scenarios
Industrial process control (main market): Pressure/differential pressure/absolute pressure measurement for pipelines, tanks, and reactors in industries such as petrochemicals, power. A variety of transmitter forms: general pressure, differential pressure, absolute pressure, remote flange type, etc.
The piezoresistive pressure transmitter is the "backbone" and "technical king" in the field of pressure measurement. It perfectly combines the precision of semiconductor technology, the low cost of large-scale production, and outstanding dynamic and static performance.
