Product Description

Product Description

• Product performance description

The QTB351 Pressure Sensitive Element is a high stability pressure measuring element with stainless steel structure. It is made
of 17-4PH stainless steel and has a maximum diameter of Φ9.5. Using CVD and PVD technology, the sensitive element is generated directly on the stainless steel elastomer, enabling highly accurate measurement of pressure. The measured pressure is transferred to the pressure sensitive chip through the elastomer, realizing the conversion of pressure to electrical signal.
