Overview
The Crystal XP2i is an intrinsically safe, high-precision digital pressure gauge engineered for mission-critical pressure verification, calibration, and process monitoring in hazardous and demanding industrial environments. Based on piezoresistive sensor technology with temperature-compensated signal conditioning, the XP2i delivers traceable, repeatable measurements across its full range — from vacuum to 15,000 psi (103.4 MPa) — while maintaining a certified accuracy of ±0.1% of full scale. Designed and manufactured under strict quality controls in Denmark, the instrument complies with international intrinsic safety standards including ATEX Directive 2014/34/EU (Category 1G, IIC T4), IECEx Ex ia IIC T4 Ga, and UL/cUL Class I, Division 1, Groups A–D. Its robust marine-grade stainless steel and polymer composite housing ensures long-term resistance to salt spray, chemical exposure, and mechanical shock — making it suitable for offshore platforms, petrochemical refineries, pharmaceutical clean utilities, and aerospace test stands.
Key Features
- Intrinsically safe design certified for use in Zone 0/20 and Class I Div 1 hazardous areas without additional barriers or enclosures
- Dual-line LCD display enables simultaneous readout of primary pressure value and secondary parameter (e.g., units, status, or logged data index)
- Menu-free interface: all functions accessed via dedicated front-panel keys — no training or manual required for routine operation
- PSV (Pressure Safety Valve) test mode provides real-time overpressure response tracking with configurable hold-and-record intervals
- Customizable pressure units including psi, bar, kPa, MPa, kgf/cm², inH₂O, mmHg, and torr — selectable per application without firmware update
- Ultra-Low-Power (ULP) architecture supports up to 12 months of continuous data logging at user-defined intervals when paired with DataLoggerXP software
- Integrated memory stores 32,000 timestamped readings with full audit trail — compatible with GLP/GMP-compliant documentation workflows
Sample Compatibility & Compliance
The XP2i is compatible with gaseous and liquid media that do not chemically attack 316L stainless steel wetted parts. It is rated for non-corrosive, non-clogging, non-crystallizing media typical of compressed air, nitrogen, hydraulic oil, water-glycol, and process steam systems. The gauge meets ISO 9001:2015 manufacturing requirements and conforms to EN 837-1 (analog and digital pressure gauges), EN 61000-6-2/-6-3 (EMC immunity/emissions), and IEC 60079-0/-11 (explosion protection). For regulated industries, the device supports 21 CFR Part 11-compliant electronic records when used with validated DataLoggerXP configurations — including user authentication, electronic signatures, and immutable audit logs.
Software & Data Management
DataLoggerXP is a Windows-based configuration and analysis tool that enables full control of XP2i’s logging parameters, including sampling rate (10 ms to 24 h), trigger conditions (threshold, slope, time), and metadata tagging (operator ID, location, test ID). Export formats include CSV, PDF reports, and XML for integration into LIMS or MES platforms. All logged datasets retain embedded calibration certificate references and sensor serial identifiers, ensuring metrological traceability. Firmware updates are performed via USB-C connection and digitally signed to maintain integrity and regulatory compliance.
Applications
- Field verification and functional testing of pressure safety valves (PSVs), relief devices, and rupture discs
- Calibration support for deadweight testers and reference standards in accredited labs (ISO/IEC 17025)
- Hydrostatic and pneumatic leak testing of pipelines, vessels, and heat exchangers
- Process validation and qualification in pharmaceutical water-for-injection (WFI) and clean steam systems
- Offshore platform instrumentation commissioning and periodic integrity checks under API RP 14C guidelines
- Aerospace component proof testing per ASTM E1012 and SAE AS5678 requirements
FAQ
Is the XP2i suitable for use in explosive atmospheres?
Yes — it carries full ATEX, IECEx, and UL intrinsic safety certifications for Zone 0/20 and Class I Div 1 environments.
Can the XP2i measure vacuum and compound pressure?
Yes — models are available as vacuum/gauge, compound (−1 to +15,000 psi), or absolute pressure variants.
Does the device require annual recalibration?
While not mandatory, Crystal recommends calibration every 12 months against NIST-traceable standards to maintain stated accuracy specifications.
What is included in the standard delivery package?
XP2i main unit, protective rubber boot, USB-C cable, quick-start guide, and factory calibration certificate with uncertainty budget.
Is wireless data transmission supported?
No — the XP2i relies on wired USB-C communication for security, determinism, and EMC robustness; Bluetooth or Wi-Fi modules are excluded to preserve intrinsic safety certification.
