TF300 High-Voltage Insulation Metal-Based Sputtered Thin-Film Sensing Elements
The TF300 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.
Features
◆ Measurement range: 0 MPa to 0.5 MPa…·250 MPa
◆ Available in gauge and absolute pressure packages
◆ Constant current and constant voltage power supply optional
◆ All-17-4PH stainless steel construction
◆ Long-term stability can reach ±0.1%FS/year
The TF300 pressure-sensitive element is a high-stability measurement component featuring an all-stainless-steel structure. With a maximum dimension of approximately 9.5 mm, it is manufactured from 17-4PH stainless steel.
The pressure-sensitive layer is formed directly on the stainless-steel elastic body using CVD and PVD technologies, enabling precise pressure measurement. Applied pressure is transmitted through the elastic body to the pressure-sensitive sensing layer, providing accurate conversion from pressure into an electrical signal.
The compact structure, wide pressure capability and excellent long-term stability make the TF300 suitable for integration into pressure sensors, transmitters and OEM pressure measurement solutions.
