Description
The NV-4AA-1KPSI-BARO-B configuration carries a 1,000 psi (70 bar) pressure module with internal barometric reference. The barometric reference lets the gauge pressure module also report absolute pressure. The Crystal Engineering nVision is a portable reference recorder built around two interchangeable measurement modules. Pressure, RTD temperature and current/voltage modules can be combined in one housing, and an internal barometric reference can be added. The unit displays and graphs live readings, logs data without a PC, and exports records through Crystal software. Calibration technicians, instrument engineers and test crews use it for field and lab calibration, leak tests and long-term pressure recording.
Key features
- Two module slots for pressure, RTD temperature or mA/voltage measurement
- Logs up to 500,000 data points at up to 10 readings per second
- Live graphical display, no PC needed for viewing trends
- Temperature-compensated accuracy from -20 to 50 °C
- Sealed housing rated to withstand submersion in about 3 feet of water
- CPF fittings with replaceable adapters to take everyday wear
Typical applications
- Calibration of pressure gauges, transmitters and switches
- Hydrostatic and leak testing of pipelines and vessels
- Long-term pressure and temperature monitoring and recording
- Reference measurement in calibration labs and on site
