The new Series 7252 offers a unique and flexible approach to automated calibration over a wide pressure range. The 7252 includes two pressure ranges with independent controllers for each range. Therefore, two calibrations can be performed simultaneously.
■Features
Range: 0 to 10 inH2O to 0 to 2500 psi (25 mbar to 172 bar)
-There are two performance models, 7252i and 7252.
・Fast control: less than 15 seconds external capacity to 15 in3 (245cc) with zero overshoot
・Stability: 0.0075% of reading/year
・Control stability: 0.001% full scale for each range
・Labview® driver can be used
■Pressure range Standard pressure range
Model 7252: Choose from two full-scale pressure ranges from 5 to 2,500 psig (400 mbar to 172 bar). An optional permanent absolute range is also available from 15 to 50 psia (1 to 4 bara).
■Pressure range Optional mode
- Absolute: Using barometric pressure reference sensors in the range 15 to 2,500 psig (1 to 172 bar)
Absolute: 5 to 2,500 psig (400 mba to 172 bar) range using barometric reference sensor, negative gauge
■ Maximum deviation of pressure, including accuracy, stability, temperature effects, and uncertainty of higher pressure standards
Series 7252: Range 5 to 2500 psi (400 mbar to 172 bar), 90 days: RSS 0.003% full scale + 0.002% reading, 1 year: RSS 0.003% full scale + 0.0075% reading
