Additel 672 Digital Pressure Calibrators -50 psi to 50 psi Differential – 0.05% Accuracy

Product Overview: Additel 672 Digital Pressure Calibrators -50 psi to 50 psi Differential – 0.05% Accuracy

ADT672

• Pressure ranges to 36,000 psi (2500 bar)
  
• HART Communication capability
  
• Measure mA or V, and with 24V loop power
  
• Easy-to-use, inexpensive pressure calibrator with uncertainty better than 0.025% FS

With advanced microprocessor technology and state-of-the-art silicon pressure sensors, the 672 series precision pressure calibrators provide a pressure calibration solution for gauges, transmitters, and switches over a wide pressure range. The 672 is a very portable device and can measure pressure precisely with a built-in pressure sensor, as well as read the current or mV produced by a transducer. It can even supply an excitation voltage to power sensors or transmitters during calibration. In order to reach 0.025% F. S. accuracy up to 10,000 psi (700 bar) and 0.1% F. S. accuracy up to 36,000 psi (2,500 bar), every silicon pressure sensor in our gauges has been specially aged, tested and screened before assembly. The 672 series precision pressure calibrators are unmatched in performance and reliability.
