Applications:
The 7250 Sys multi-range pressure calibration system is a complete, turn-key systems ideally suited for the test and calibration of the following:
• Pressure sensors
• Pressure transducers
• Pressure transmitters
• Pressure switches
• Pressure gauges
The third-generation in multi-range pressure calibration systems For over 35 years, Ruska, now under the name Fluke Calibration, has supplied multi-range pressure calibration systems. These systems provided maximum performance over a wide pressure range and relieved the customer of the need to utilize internal resources to configure a comprehensive pressure calibration system.
These systems consisted of multiple pressure controllers multiplexed to a single test port with automatic range switching and included ancillary components required for operation, such as vacuum pumps for sub atmospheric pressure control and gas boosters for high pressure systems. The 7250 Sys represents a significant advancement in
performance and capability coupled with a size reduction and cost saving design.
The 7250 Sys is based on Ruska’s popular Series 7250 digital pressure controllers featuring our unique quartz sensor
that provides unmatched precision and long term stability. The 7250 Pressure Controllers also utilize digital control
valve technology that provides fast response pressure control with zero overshoot allowing separate repeatability and
hysteresis checks of the DUT.
Three different 7250 Sys configurations are available depending on performance and pressure range requirements:
• Eight ranges to 1 000 psi (70 bar)
• Eight ranges to 2 500 psi (170 bar)
• Twelve ranges to 2 500 psi (170 bar)
Although each of the above configurations includes multiple pressure ranges and controllers, the 7250 Sys has a single point of operation featuring a color, Active Matrix display. The 7250 Sys can also be operated via PC with the
included IEEE-488 interface. All supporting subsystems, such as a vacuum pump, gas pressure booster, pressure regulators and power distribution are integrated into a single bay cabinet with easy access doors, cooling fans, and casters.
