Micro-fused pressure sensors and transmitters are highly versatile and find use across a broad spectrum of industries thanks to their robust design, high accuracy, and reliable performance under demanding conditions.


Hydraulic and Pneumatic Systems


In hydraulic servo control systems, micro-fused pressure transmitters provide real-time pressure monitoring and control, ensuring precise mechanical movement and optimal system response. Their wide pressure range and shock resistance make them ideal for use in hydraulic cylinders, motors, and valve blocks, where stable pressure control is critical. For specialized applications involving hydrogen, consider our detailed insights on hydrogen pressure transducers that address unique challenges in this field.

Micro fused Pressure Transducer Use for Industrial Process Control


Microfused pressure sensors excel in industrial process control applications such as plastic molding, where monitoring pressure inside mold cavities is essential to ensure product quality and reduce scrap. Their leak-proof stainless steel diaphragm and temperature compensation features maintain accuracy even in harsh environments with corrosive or contaminated media, and notably, these sensors operate without any oil filling, eliminating leakage risks. For a deeper understanding of diaphragm designs and their benefits, check out our article on flush diaphragm pressure transducers.

How Micro-Fused Pressure Sensors Work


Micro-fused pressure sensors function by integrating a silicon strain gauge with high-temperature glass directly onto a stainless steel diaphragm. This fusion process forms a single, solid sensor element that accurately converts pressure into an electrical signal with exceptional stability. By eliminating the need for oil filling, these sensors achieve a leak-proof design, making them ideal for use in corrosive or sensitive environments. Additionally, advanced temperature compensation ensures precise measurements across a broad temperature range, enabling reliable operation even in the most demanding industrial settings.
