The Glass Micro-Melt Pressure Sensor is a highly reliable solution for pressure detection in various industrial applications. This sensor utilizes the Glass Micro-Melt technology, which combines asilicon strain gaugewith high-temperature sintering and stainless steel thin film bonding. These features provide the sensor with high sensitivity, stability, and excellenttechnical control, making it suitable for large-scale production.
The silicon strain gauge is sintered at high temperatures onto a stainless steel thin film, forming a bridge with four equivalent resistors. When pressure is applied to the gas or liquid on the other side of the thin film, it undergoes a slight deformation, causing the four strain gauge resistors to change. The bridge produces an output voltage that is proportional to the applied pressure when a voltage is supplied.
Thedifferential outputof thebridge needsto be compensated for temperature and normalized to a 0-100mV output before being amplified and converted into a standard industrial signal, such as 4-20mA or 0-5V. The electronic components require protection from the industrial environment with packaging and housing.
One of the advantages of the Glass Micro-Melt Pressure Sensor is its use ofaviation technologyin modern equipment. By melting the micro-machined silicon pressure-sensitive resistor strain piece onto the stainless steel isolation sheet using high-temperature glass, the sensor’s long-term stability performance in industrial environments is improved, and the P-N result effect phenomenon that may occur during traditional micro-machining manufacturing processes is avoided.
Furthermore, the Glass Micro-Melt Pressure Sensor is highly reliable, with no hysteresis, high sensitivity, and excellent technical control. Thebonding processof the glass technology also avoids the effect of temperature, humidity,mechanical fatigue, and media on the adhesive and material.
In summary, the Glass Micro-Melt Pressure Sensor is an excellent choice for high-pressure overload applications, providing reliable and accurate pressure detection in various industrial environments.
