nVision Intrinsically Safe Reference Pressure Recorder

The nVision Intrinsically Safe Reference Pressure Recorder is designed for verification and calibration in the field, explosive or laboratory environment:

  • Dial and digital devices showing and recording gauge, absolute and differential pressure, as well as current, voltage and temperature;
  • Pressure transmitters of various types;
  • Technical manometers;
  • Pressure switch.

The calibrator provides a wide range of capabilities for testing a variety of valves, burst discs, recorders and other devices.

Key Features:

  • Intrinsically safe design 0ExiaIIBT3 / T4Ga X;
  • Measurement and registration of gauge and – with the installed barometric module – absolute pressure, as well as differential pressure under the operating pressure, when installing two pressure modules;
  • Measurement and registration of pressure / differential pressure in the ranges of -0.1 … 100 MPa with a relative error of ± 0.025%;
  • Measurement and registration of direct current, voltage, resistance (mA, V, Ohm) with a relative error of ± 0.015%;
  • Datalogger up to 1 million points with simultaneous registration of readings of two modules;
  • Graphic display with backlight;
  • Rugged weatherproof IP67 case (withstands immersion in water up to 1 m for 30 minutes);
  • Small dimensions and weight;
  • Delivery both as a separate digital meter and as part of calibration systems with pneumatic and hydraulic hand pumps in aluminum or plastic cases;
  • Unique system of quick-release fittings CPF for hand tightening, including for high pressure (up to 70 MPa);
  • CrystalControl software, included as standard, provides extensive control of the calibrator, data logging and data processing on a PC.
  • The nVision is approved for use as a portable test instrument for Marine use and complies with Det Norske Veritas’ Rules for Classification of Ships, High Speed & Light Craft and Offshore Standards.
