QTB354 High-Voltage Insulation Metal-Based Sputtered Thin-Film Pressure-Sensitive Chip

The QTB354 pressure-sensitive element is a high-stability measurement component with a stainless steel structure. Its maximum dimension is 9.5 mm, and it features a 17-4PH stainless steel construction. The sensitive element is directly grown onto the stainless steel elastomer using CVD and PVD technologies, enabling precise pressure measurement. The pressure to be measured is transmitted through the elastomer to the pressure-sensitive chip, achieving an accurate conversion from pressure to an electrical signal.
