CY-ZJ-1C Capacitive Thin Film Vacuum Gauge Tube

This type of gauge tube uses a high-quality, imported ceramic capacitive pressure sensor as the pressure-sensitive element. It features various standard or non-standard tube packaging structures. The capacitive diaphragm inside the sensor is made of high-purity Al₂O₃ ceramic, which is corrosion-resistant, impact-resistant, non-aging, stable, and reliable. The sensor can perform temperature compensation within the range of -20 to +80°C, keeping the temperature error at zero and full scale within ±0.5%. A specially developed circuit board ensures stable and reliable performance and a compact design.
