PTB301 series pressure sensor cores
Summary:
This series of pressure sensor is the core with high resistance strain gauge, after thousands of times high-performance chipsets, low temperature, high impact fatigue cycle aging process, through the whole seal welded stainless steel (laser welding) and refined.
Strict check process, and improve the assembly process to ensure the high quality of the products. No irrigation filling liquid temperature tiny integrated structure, stainless steel can adapt to bad conditions.
