2. Product Introduction
Structure B (Architecture hook): Engineered for semiconductor processing equipment, vacuum systems, wind-tunnel research, and precision industrial gas metrology, the MKS 220CD-00001C2B functions as a high-accuracy differential capacitance manometer within the Baratron 220 series. Designed to measure true total or differential pressures independently of gas composition, this instrument utilizes a tensioned metal diaphragm design that translates minute pressure variations into high-level electrical DC voltage or current signals.
Housed in a ruggedized, corrosion-resistant metallic enclosure designed to withstand demanding vacuum environments and process gas exposure, the internal electronics deliver exceptional zero/span stability, high linearity, and rapid response times for critical closed-loop pressure control applications.

4. Global Compliance & Industry Certifications
Type-test verification and rigid metrological standards compliance are mandatory for high-precision pressure transducers deployed in vacuum and semiconductor fabrication lines.
- Expected Certifications: CE Mark (EMC and Low Voltage Directives), RoHS material compliance declarations, and individual factory calibration traceable to national standards.
- Safety Relevance: Integrated overpressure protection limits and all-welded Inconel wetted surfaces prevent mechanical diaphragm rupture or chemical leakage when handling corrosive process gases.
- Audit Note: Verify that full-scale range ratings, process fitting compatibility, and input power supply requirements match your vacuum system specifications prior to installation.
5. Long-Term Storage & Asset Preservation Guide
Veteran Maintenance Note: Storing precision capacitance manometers requires strict environmental and mechanical protection to prevent zero drift and contamination of the internal vacuum sensor cavity.
- Moisture & Particle Protection: Keep the pressure transducer hermetically sealed inside its original anti-static moisture-barrier bag with protective blanking plugs securely fitted to all process ports.
- Climate Baseline: Store the inventory in a clean, dry location maintaining relative humidity strictly below 50% non-condensing, and ambient storage temperatures between -20°C and +40°C.
- Mechanical Preservation: Handle the unit with care; avoid physical shock or dropping, as high-impact forces can permanently alter the delicate internal diaphragm tension and induce zero offset errors.
6. Physical Installation Prerequisites
- Ensure that the vacuum chamber or gas line is fully isolated, vented, and safe before mounting or removing the pressure transducer.
- Inspect process connection fittings (such as VCR or tube fittings) for cleanliness, ensuring zero particulate contamination is present before mating.
- Mount the unit securely in the recommended orientation (typically vertical or horizontal as specified by system guidelines) and connect the multi-pin circular cable harness, ensuring proper shielding to eliminate electrical noise.
7. Buyer’s FAQ (Logistics & Compliance Focus)
- What Harmonized System (HS) code governs international customs clearance?
The standard global export classification for this industrial pressure transducer is 9026.20.4000 (Instruments and apparatus for measuring or checking pressure of liquids or gases).
- How does Country of Origin (COO) verification impact cleanroom and plant auditing?
Accurate origin tagging on shipping documentation ensures compliance with international trade frameworks and regional import regulations (typically United States manufacturing origin).
- Does this capacitance manometer require field zeroing upon installation?
Yes, due to shipping and handling dynamics, precision capacitance manometers require zero adjustment after final installation and evacuation to baseline reference pressure.
- What level of transit insurance should be specified?
Always mandate fully declared-value, tracked international air cargo insurance to protect precision internal sensor assemblies and connector pins against drop impacts during transit.
