The third-generation in multi-range pressure calibration systems
For over 35 years, Ruska, now under the name Fluke Calibration, has supplied multi-range systems for pressure sensor calibration, pressure transducer calibration, pressure transmitter calibration, pressure switch calibration, and pressure gauge calibration. 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 the popular Series 7250 digital pressure controllers featuring the 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 device under test.
