PC10PTFE pressure sensor
Product Overview
PC10PTFE, PTFE type silicon piezoresistive pressure sensor is the core component of pressure sensor and pressure transmitter as the high performance pressure sensitive element. It adopts integrated structure, high static pressure resistance, stable and reliable.
PC10PTFE sensor is a diffused silicon pressure sensitive chip encapsulated in a 316L stainless steel housing. The external pressure is transmitted to the sensitive chip through the stainless steel diaphragm coated with PTFE and the internally sealed silicone oil. The sensitive chip does not directly contact the measured medium, forming a fully solid-state structure for pressure measurement. Therefore, this product can be used in various occasions, including harsh corrosive media environments.
PC10PTFE sensor uses an O-ring for pressure sealing, which is easy to install.
