Additel 761-BP



Product Description

Additel 761-BP

  • Fully automated pressure calibrator with built-in pressure generator / controller from 100hPa to 1200hPa
  • 0.01%FS accuracy
  • Built-in filter and liquid trap with venting system prevents contamination of the calibrator
  • Portable (16.3 lb)

With a built-in high performance electronic pump and precision pressure controller, the 761 series portable automated pressure calibrators provide a turn-key solution for calibration of gauges, transmitters, and switches both in the field and in the laboratory. In a portable package, this calibrator can automatically generate pressures  from 100hPa to 1200hPa.

The 761-BP is specially designed for low pressure calibration . With a quartz pressure sensor , the accuracy of 761-BP can achieve 0.01%FS accuracy .

In addition to the pressure generation, control, and measurement capabilities, the 761 also features HART communication capability, supplies 24V loop power, and reads the current or voltage produced by the pressure transducers. The 761 is a state of the art automated pressure calibrator which brings automated pressure calibration to the field.

* One year accuracy (including 1 year stability). FS specification applies to the span of the module range.

** 0.05% FS accuracy (including 6 months stability). One year accuracy is 0.05% FS calibration accuracy combined with 0.05% FS one year stability.

*** Additel 761 calibrators support 160A series intelligent digital pressure modules that are available for gauge, vacuum and absolute pressure from -15 psi to 10,000 psi (-1 bar to 700 bar). Accuracy from 0.025%FS includes operation over 14°F to 122°F (-10°C to 50°C), one year stability and calibration uncertainty. For detailed specification refer to 160A series pressure modules datasheet.
