MKS 627D01TDC1B Capacitance Manometer Pressure Transducer – Baratron 627D Series
When a critical vacuum process loses pressure measurement accuracy, the consequences cascade instantly — deposition rates drift, etch uniformity collapses, and entire wafer batches are scrapped. In semiconductor fabs, chemical vapor deposition (CVD) chambers, and high-purity gas delivery systems, the pressure transducer is not a peripheral sensor; it is the heartbeat of process control. Without a reliable, thermally stable, and contamination-resistant measurement device, operators are flying blind in environments where a 1 mTorr deviation can mean the difference between a functional chip and a costly reject.
The MKS 627D01TDC1B is a precision capacitance manometer from MKS Instruments’ industry-defining Baratron® 627D Series — a product line that has set the global benchmark for vacuum pressure measurement for decades. This specific model is engineered for full-scale ranges and temperature-controlled operation, delivering the absolute accuracy and long-term stability demanded by the world’s most advanced semiconductor OEMs, research institutions, and industrial vacuum system integrators. As a gas-type independent sensor, it measures true pressure regardless of the process gas composition, making it indispensable in multi-gas process environments.

Key Features & Benefits
- Gas-Type Independent Measurement: Capacitance manometer technology measures absolute pressure regardless of gas species — no correction factors needed for N₂, Ar, O₂, HF, or exotic process gases.
- Thermally Stabilized Sensor Head: The 627D’s heated sensor design eliminates condensation and thermal drift, ensuring measurement integrity in reactive and corrosive gas environments.
- High Accuracy & Repeatability: Delivers ±0.5% of reading accuracy (full scale), meeting the stringent requirements of semiconductor process control and R&D applications.
- Inconel® Diaphragm: Superior corrosion resistance against aggressive process chemistries including halogen-based etch gases and acid vapors.
- Wide Dynamic Range: Capable of measuring from atmosphere down to high-vacuum ranges, adaptable across multiple process steps.
- Direct OEM Replacement: Drop-in compatible with existing MKS Baratron 627D installations — minimizes downtime during maintenance or upgrade cycles.
- Long Service Life: Robust construction and MKS’s proven diaphragm technology ensure extended MTBF in continuous 24/7 production environments.
