Description
PL303-13 Level transmitter has small diameter as 13mm . It adopts
high performance diffused silicon pressure sensor as the measuring
element .The products has reliable amplified circuit and precision
temperature compensation, to transfer the gauge or absolute
pressure of measurement medium to standard voltage or current
signal.
PL303-13 level transmitter is widely used in sewage, river and
lakes treatment as well as channel, large rivers, l reservoirs and
coastline monitoring. This product has got intrinsic safety
certification, explosion proof certification and CE certification.
The lead of two-wire circumfluent is no-polarity
