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.
