Pressure generation and control

The internal, motorized pump provides an easy, efficient alternative to time consuming, tiring hand pumps. For applications that involve filling a large volume with pressure, the 3130 allows for connection to an external gas supply such as compressed plant air. The pressure can be fine-tuned using the variable volume.

Pressure measurement

The 3130 offers an onboard pressure sensor with a full scale of 2 MPa (300 psi, 20 bar) and an accuracy of ± 0.025 % reading + 0.01 % FS (includes precision, one-year stability, uncertainty of the calibration standard, and temperature effects). In addition, the 3130 can be used with the Fluke 700P pressure module series to improve measurement performance across the entire range.

Electrical measurement

The 3130 offers electrical measurement capabilities for calibrating pressure transducers and transmitters, including measurements of 4 to 20 mA or 0 to 30 V dc. In addition, the 3130 provides 24 V dc supply to power the device under test and can generate current in the 4 to 20 mA range.

Portability

The 3130 is built into a ruggedized case with internal storage for power supply, test leads, and fittings. In addition, it includes a rechargeable, NiMH battery, allowing for approximately 50 hours of operation. When using the internal pump, the battery is sufficient to provide up to 100 calibration cycles to 300 psi. The battery is recharged by simply plugging the unit in using the included universal mains adapter.
