Fluke Ruska 7250LP Digital Pressure Controller

7250LP Automatic Low Pressure Controller with 0.005% measurement accuracy for precise differential pressure calibrations

• Dual range, select from 2.5/7.5 kPa (10/30 inH2O) or 5/15 kPa (20/60 inH2O) or 10/25 kPa (35/100 inH2O) range combinations
• Precision: 0.005 % of reading from 25 % to 100 % Full Scale (FS)
• Control stability: 0.004 % of each range
• Resolution to 0.01 Pa (0.0001 inH2O)
• Time to set point: 30 seconds with no overshoot

The 7250LP low pressure controller/calibrator, part of the versatile Series 7250 family, is specifically designed to meet the demanding performance requirements of calibrating low pressure sensors, transducers, mechanical gauges, portable calibrators and their plug-in modules. To accommodate bidirectional devices,
the 7250LP can be supplied to operate in both positive and negative gauge modes.
The 7250LP offers unmatched performance and enhanced control stability. Utilizing multiple ranges in a single instrument, the 7250LP combines precision, stability, speed and affordability. The 7250LP has a unique quartz sensor, the most accurate pressure sensing technology available in a digital pressure calibrator. Each
quartz sensor is manufactured and tested to provide the ultimate performance required by a Fluke Calibration pressure calibrator, ensuring that every customer receives the highest quality, precision and stability in their instrument.

The 7250LP is available in three different range configurations:
- 2.5/7.5 kPa (10/30 inH2O)
- 5/15 kPa (20/60 inH2O)
- 10/25 kPa (35/100 inH2O)

Each combination provides a precision to 0.005 % of reading from 25 to 100 % of the higher range. For pressures from 0 to 25 %, the precision is a fixed error equal to 0.005 % of 25 % FS. This unmatched precision is achieved by the unique quartz pressure sensing technology that puts the pressure in direct contact with
the quartz element, eliminating mechanical linkages and metal diaphragms.
