AMETEK Crystal nVision – Reference Pressure Recorder

Description

AMETEK Crystal nVision – High-Accuracy Reference Pressure Recorder

The Crystal Engineering nVision Reference Recorder by AMETEK Calibration is an intrinsically safe, portable digital pressure recorder designed for precision measurement, instrument calibration, and industrial pressure testing.

Unlike conventional pressure gauges and mechanical chart recorders, the nVision allows technicians to measure, record, and visualize pressure changes in real time using its graphical display.

Its interchangeable measurement modules provide flexibility for pressure, temperature, current, voltage, and switch testing, making the instrument suitable for industrial maintenance, calibration laboratories, oil and gas facilities, and field inspection applications.

Key Features and Benefits

• High Measurement Accuracy: Up to ±0.025% of reading with selected pressure modules and measurement ranges.
• Wide Pressure Range: Interchangeable pressure modules supporting applications up to 15,000 psi (1,000 bar).
• Real-Time Graphical Display: View pressure trends and identify changes directly on the instrument.
• High-Capacity Data Logging: Stores approximately 1 million data points when recording a single module.
• Fast Recording: Captures measurements at rates up to 10 readings per second.
• Multiple Measurement Functions: Supports gauge pressure, absolute pressure, differential pressure, temperature, current, voltage, and switch testing, depending on installed modules.
• Temperature Compensation: Maintains specified accuracy across −20°C to +50°C.
• Intrinsically Safe Design: ATEX and IECEx approvals for suitable hazardous-area configurations.
• Rugged Construction: IP66/IP67 protection, including submersion in 1 metre of water for up to 30 minutes.
• USB Data Transfer: Mini-USB interface for connection to compatible computers.
• CrystalControl Software: Export measurement records to Excel-compatible formats, CSV, PDF, or digitally signed PDF files.
• Long Battery Operation: Typically up to 200 hours using four AA batteries under specified conditions.
