7350 Pneumatic High Pressure Controller
This product is discontinued. For a replacement please see the 8270A and 8370A Modular High-Pressure Controllers / Calibrators »
- Pneumatic full scale (FS) ranges to 10 000 psia (700 bara)
- Precision to 0.01 % of range • Stability 0.01 % of range per year
- Up to three ranges available in one instrument
- Automates high pressure pneumatic calibrations
- Available in bench top or cart-mounted configurations
- FS pressure ranges of 6 000 psi (415 bar) or 10 000 psi (700 bar)
The Model 7350 high pressure pneumatic controller provides a safe, easy to use and effective means of automating high pressure test and calibration of a wide range of pressure measuring devices. In control mode, these controllers simultaneously measure and control pressure, and can be used for the calibration and testing of pressure gauges, transducers, pressure switches and production pressure instruments.
Precision and stability
The Model 7350 controller uses a quartz transducer for unmatched performance in conducting automated high pressure testing and calibration. Precision levels are 0.01 % of FS for pressures to 10 000 psi (700 bar). Stability is 0.01 % of FS per year, providing for an annual recalibration interval.
Automating high pressure test and calibration
The Model 7350 features an easy-to-use, menu-driven user interface for straightforward, simple operation. Step up/down: For calibrations where the increments are fixed intervals, enter a user-defined step value. The controller increases or decreases the pressure by the step amount with a single keystroke. No more lengthy keystroke sequences to program.
Sweep test: For simple exercising routines, as with dial gauges, enter a start value, a stop value andumber of times to repeat the cycle. The controller automatically exercises the device under test prior to the calibration run.
Onboard programs: For frequently used or lengthy calibrations, the controller can store up to 20 user-defined programs/profiles with up to a total of 1000 steps in internal memory.
Computer interface: Every controller is provided with both an RS-232 and IEEE-488 interface, and the controller syntax follows SCPI protocol for easy programming. A LabVIEW® driver is also available.
Intecal Software: Provides complete automation of pressure calibrations. A ready-to-use software package that interfaces with all former Ruska controllers, along with popular digital multimeters to provide full, closed loop calibrations. Intecal also provides calibration management solutions by providing a printout of calibration results and performance analysis, and stores historical data.
Triple range option
All ranges can be supplied with the triple scale option to provide three ranges with a single sensor.
Versatility to handle almost any high pressure calibration
The Model 7350 high pressure controller is versatile enough to handle almost any type of high pressure calibration.
Pressure ranges: Available in standard pressure ranges of 6 000 or 10 000 psia (415 or 700 bara) FS. Choice of media: Clean, dry laboratory grade air or nitrogen.
Pressure units/scales: Features two userdefined, programmable units of measure, and twelve standard units: inHg at 0 °C, inHg at 60°C, kPa, bar, psi, inH2O at 4°C, inH2O at 20 °C, inH2O at 60 °F, kg/cm2, mmHg at 0 °C or cmH2O at 4 °C.
Head pressure: Automatic correction for given head pressure differences
Zeroing: With a few keystrokes, the controller will automatically zero the sensor.
Protection of the device under test: Set upper and lower pressure limits to ensure protection of the device under test
Options: The Model 7350 is an absolute instrument and includes a tare feature for simulated gauge mode operation. The following option is available: Triple scale option provides three ranges with single sensor
The high pressure controllers can easily automate your high pressure test and calibration workload. These controllers are easy to use, easy to maintain and have the reliability, the performance and the features that you want.
