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. |
