Measure / Record: nVision Reference Recorder

*Not recommended for oxygen service.

• Calibrate pressure transducers, switches, transmitters and gauges
• Calibrate natural gas correctors and flow computers
• Pressure relief valve testing
• Field datalogging of pressure and temperature
• Record water hammer events
• Leak testing with simultaneous graphing of pressure and temperature
• Temperature monitoring and recording
• Pass/fail events for pressure bearing vessels such as gas cylinder, flow meter, etc.
• Start and stop recording runs remotely from CrystalControl

Included with every new nVision Reference Pressure Recorder is an A2LA accredited calibration certificate with test data recorded at 5 different temperatures - proving that it meets published specifications over the entire operating range. You won't get this kind of detailed report anywhere else!

Pressure Measurement 

Pressure Ranges

Pressure Accuracy

30% to 100% of Full Scale: ±(0.25% or Reading), ±(0.05% of Reading), ±(0.1% of Reading)
0 to 30% of Full Scale: ±(0.0075% of Full Scale), ±(0.015% of Full Scale), ±(0.03% of Full Scale).
Vacuum, for 300 PSI and lower pressure modules: ±(0.06% of Full Scale*, typical), 

* Full Scale = -14.5 PSIG (not recommended for continuous use below -14.5 PSIG)

Gauge Pressure Accuracy

  Absolute Pressure Accuracy

Differential Pressure Accuracy (Tare Mode with Equalizing Valve)

Temperature Measurement: RTD Module (P/N: RTD100)

Supports Pt100 RTD or PRT (100 Ohms at 0°C Resistance Temperature Detector) sensors conforming to DIN/IEC 60751 (or IEC751) with US, Euro and Lab calibration curves. Each RTD 100 comes with P/N 3953 RTD Connection Kit.

Current, Voltage & Switch Test: mA/V Module (P/N: MA20)

Intended for use with a 4-20mA loop measurement. This module is also capable of measuring 24VDC supply voltages. Additionally the module has an auxiliary fixed output for use in switch open/closure testing. Each MA20 module comes with P/N 3952 test lead kit.

WARNING: Never install two (2) MA20 modules simutaneously.  This configuration may permanently damage your nVision.
