    Overview
     

     Overview

    		 
    • In-place system calibration and on-line monitoring without disturbing process tubes with optional process valve actuator and test jacks
    • Ultrathin profile ideally suited for DIN rail mount reduces installation and calibration costs
    • High accuracy, two options; 0.25% or 0.50% of span designed for use in critical monitoring of cleanrooms for pharmaceutical, biotechnology, medical device and semiconductor controlled manufacturing environments
    • Extremely robust MEMS silicon sensor technology provides very high accuracy, sensitivity, stability and durability
    • NIST traceable 9 point calibration with certifi cate
    • Front side accessible zero and span adjustment potentiometers
