PRESSURE TRANSMITTERS

   
     

HIGH AND LOW PRESSURE, DRAFT, VACCUM AND COMPOUND RANGES

 

Lectrotek Gage Pressure Transmitters are suitable for gage pressure, draft, vacuum and compound range measurements for industrial fluids. They are available in standard pressure range versions (1 bar to 600 bar), vacuum and compound ranges etc. Output provided is standard 4-20 mA for these 2-wire loop powered transmitters, although 3-wire versions are available on request. The transmitters are peizo-resistive and strain gage principle based, and offer benefits in terms of economy, accuracy, reliability, high overpressure capability and MTBF.

   

FEATURES
