Fluke – 7050/7050i Digital Pressure Indicators

מאפיינים מרכזיים

The Series 7050 digital pressure indicator expands upon the popular line of Series 7000 products such as the Series 7250 digital pressure controller and Series 7252 dual output pressure controller. The 7050 provides an instrument for applications that only require pressure measurement.

Three models are available to meet a wide range of applications:
* Model 7050i with advanced percent of reading precision
* Model 7050 with a high performance-to-price ratio
* Model 7050LP for low pressure measurements

  • Pressure ranges from 0 to 10 inH2O and 0 to 1 500 psi (0 to 25 mbar and 0 to 100 bar)
  • Choose from three models: 7050i, 7050 and 7050LP
  • Model 7050i provides advanced precision of 0.005% of reading
  • Model 7050 provides 0.003 % of full scale precision
  • Stability: 0.0075 % of reading per year
  • Active matrix color screen with enhanced navigation menus
  • Languages: English, French, Chinese, German, Japanese, Spanish and Italian

0.003% of FSModel 7050i
From 25% to 100% full scale (FS): 0.005% of Reading Below 25% FS: 0.005% of 25% FSPrecision is defined as the combined effects of linearity, repeatability and hysteresis throughout the operating temperature range. Expression of total uncertainty conforms with the recommendations of the ISO Guide to the Expression of Uncertainty in Measurement.
Stability All models: 0.0075% of reading per year
Display Resolution User selectable to 1:1,000,000
Negative Gauge Precision (optional) Model 7050
0.003% of FSModel 7050i
0.005% of 25% FS or 0.0005 psi (0.034 mbar), whichever is greater
