Digital Submersible Diesel Pressure Level Sensor PL303 SDI - 12
ATECH Factory PL303 SDI-12 Digital Submersible Diesel Pressure Level Sensor
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.
