Overview
The York Instrument CPC2000 Portable Micro-Pressure Controller is an electronically actuated, high-stability pressure control system engineered for precision generation and regulation of low-pressure signals in the range of 0.1 to 100 kPa (absolute or gauge, configurable). It operates on the principle of closed-loop electronic pressure control, utilizing a built-in microprocessor-driven servo-valve system coupled with a dual-mode integrated pump capable of delivering both positive and negative pressure (vacuum) outputs. Unlike open-loop manual regulators or pneumatic controllers, the CPC2000 maintains setpoint stability through continuous real-time feedback from its internal high-resolution pressure transducer, enabling dynamic compensation for thermal drift, line pressure fluctuations, and load variations. Its compact, handheld form factor—combined with internal lithium-ion battery operation—makes it suitable for field calibration, on-site verification, and mobile metrology tasks where portability and independence from mains power are critical.
Key Features
- Full-range micro-pressure control from 0.1 kPa to 100 kPa with ±0.1 % full-scale (FS) accuracy, traceable to national standards
- Integrated dual-mode electric pump supporting both pressurization and vacuum generation without external air supply
- Automatic zero-point calibration at power-on, eliminating manual zero drift correction and ensuring baseline repeatability
- Rechargeable Li-ion battery providing up to 8 hours of continuous operation; also compatible with universal AC adapter (100–240 VAC)
- Digital front-panel interface with intuitive menu navigation, adjustable step increments (0–50 % FS), and direct setpoint entry via rotary encoder
- Leak test mode: locks pressure in connected test circuit and logs decay rate over time, with automatic calculation of pressure drop per minute (kPa/min) and elapsed duration
- RS-232 and USB-B interfaces support bidirectional communication for remote control, data logging, and integration into automated calibration workflows
Sample Compatibility & Compliance
The CPC2000 is designed for compatibility with standard NPT 1/8″ and G 1/8″ pressure ports and supports connection to a wide variety of low-pressure devices including differential pressure transmitters, HVAC static pressure sensors, HEPA filter integrity testers, laminar flow hood monitors, medical gas manifolds, and cleanroom differential pressure switches. All internal wetted parts are constructed from stainless steel and PTFE-compatible elastomers to ensure chemical inertness and long-term stability. The instrument complies with EN 61326-1 (EMC for laboratory equipment), IEC 61000-4 series immunity requirements, and carries CE marking for use within the European Economic Area. Each unit ships with a factory-issued calibration certificate indicating as-found/as-left values against reference standards accredited to ISO/IEC 17025. Optional DKD/DAkkS-accredited calibration certificates are available upon request and meet the evidentiary requirements for GLP, ISO 9001, and ISO 14644-3 audit trails.
Software & Data Management
The CPC2000 supports ASCII-based serial protocol over RS-232 and virtual COM port emulation via USB, enabling seamless integration with third-party calibration software such as MET/CAL, Beamex CMX, or custom Python/LabVIEW applications. Firmware includes timestamped event logging (e.g., setpoint changes, leak test initiation, zeroing events) stored in non-volatile memory. Logged data can be exported in CSV format for traceability and report generation. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements when used in conjunction with validated host software—user access levels, electronic signatures, and change history are managed externally but fully supported by the device’s deterministic command-response architecture.
Applications
- Field calibration of HVAC duct static pressure sensors and building automation system (BAS) transmitters
- Verification and adjustment of differential pressure monitors in ISO Class 5–8 cleanrooms and pharmaceutical isolators
- Functional testing and sensitivity validation of medical ventilator pressure sensors and anesthesia machine alarms
- Leak rate quantification for HEPA filter housings, gloveboxes, and containment enclosures per ISO 14644-3 Annex B
- Reference pressure source for benchtop calibrators and deadweight testers operating below 100 kPa
- Research-grade pressure stimulus delivery in fluid dynamics and microfluidic device characterization
FAQ
What pressure units does the CPC2000 support?
The device supports kPa, mbar, psi, inH₂O (at 4 °C), mmH₂O, and cmH₂O, selectable via the MENU interface.
Can the CPC2000 generate vacuum and positive pressure simultaneously?
No—it operates in either positive pressure or vacuum mode per session; switching requires manual reconfiguration via the control menu.
Is the internal pressure sensor user-replaceable?
No—the transducer is hermetically sealed and calibrated as part of the OEM assembly; replacement requires return to authorized service centers.
Does the device support analog output for process monitoring?
No analog output is provided; all data exchange occurs digitally via RS-232 or USB.
How often should recalibration be performed?
York Instrument recommends annual calibration under normal use conditions; frequency may increase in high-cycle or harsh-environment applications per ISO/IEC 17025 Clause 7.7.
