Product Details

Honeywell differential pressure transmitter STD725-E1AS4AS-1-0-AHT-12S-A-20A0-00-0000


All ST 700  transmitters are modular in design supporting the user’s  ability to replace meter bodies, add indicators or change  electronic modules without affecting overall performance or  approval body certifications. Each meter body is uniquely  characterized to provide in-tolerance performance over a wide  range of application variations in temperature and pressure  and due to the Honeywell advanced interface, electronic  modules may be swapped with any electronics module  without losing in-tolerance performance characteristics. 


Best in Class Features:  

o Accuracies up to 0.05% of span 

o Stability up to 0.02% of URL per year for 5 years  

o Automatic static pressure & temperature compensation  

o Rangeability up to 100:1  

o Response times as fast as 100ms  

o Alphanumeric display capabilities
