 Martel BetaGauge 311

Features:
  • One isolated, stainless steel pressure sensor
  • Temperature compensation to ensure field use accuracy
  • External pressure module connection supports all BetaPort-P pressure modules
  • Large Backlit configurable display for 1,2 or 3 variables
  • Switch test on Pressure (Internal or External)
  • % Error and damping functions
  • RS-232 port for remote operation


  Description

The Advanced Pressure Calibrator is a general purpose, high accuracy pressure calibrator with special features intended to facilitate calibration of mass flow computers. With one internal pressure range and an available adapter for external BetaPort-P pressure modules, the possibilities are extensive. In addition, the advanced pressure calibrator has a port to connect a precision RTD probe for the temperature factor calibration required for electronic flow meters (EFMs).

The available internal sensor ranges (in PSI) are: 5,15,30,100,300, 500, 1000, 15000, 3000, 5000, and 10000. Pressure may be displayed in the user's choice of engineering units.
