Ceramic Retainer for Sensor Head
High-performance Ceramic Retainer for Sensor Head, fully compatible with Inficon specifications. Precision water-cooled design ensures maximum stability and durability for film thickness monitoring. A cost-effective alternative to original parts.
1. Product Definition and Names
Names: Ceramic Retainer for Sensor Head, Crystal Sensor, Quartz Monitor Head. Material: The body is typically made of high-grade stainless steel (304/316L) or oxygen-free copper, featuring high-insulation ceramic holders and gold-plated contacts to ensure structural stability and signal transmission in high-vacuum/high-temperature environments.
2. Position in the Vacuum Coating Machine
The sensor head is installed at the top or side inside the vacuum chamber, facing the evaporation source. It connects to the external thickness monitor via a vacuum feedthrough. As the carrier for the quartz crystal, it is the core sensing component directly exposed to the deposition environment.
3. Core Functions
The Ceramic Retainer for Sensor Head plays three vital roles: ① Signal Acquisition & Transmission: Precision internal contacts press against the quartz crystal to transmit frequency changes to the monitor in real-time, enabling precise control of nanometer-scale thickness and deposition rates. ② Crystal Protection & Fixation: A quick-insert or screw-cap design securely locks the crystal, preventing displacement and ensuring reliable electrical contact. ③ Cooling & Heat Dissipation: The built-in water-cooling channel rapidly removes radiant heat, preventing frequency drift or crystal failure caused by overheating, ensuring long-term process stability.
