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
PL303 series are submersible level transmitters with the fully welded structure. The product utilizes a piezoresistive sensor with proved long term stability and reliability and a special digital compensation circuit that is housed in a rugged stainless steel housing. It offers an integrated structure, supports standard outputs, and cable options of multiple material for a wide range of operation temperature. Specifically, PL303 is mostly used in the level monitoring of refined oils, such as gasoline,diesel, kerosene, etc., PL303 is mostly used in the level monitoring of chemicals, such as methanol, ethanol, diesel exhaust fluid (DEF), diesel engine coolant, etc. Both two level transmitters are also applicable for other environments with high requirements for wear resistance, protection, or explosion-proof.
