ATECH Factory PL303 SDI-12 Digital Submersible Diesel Pressure Level Sensor
PL303 series is an all-welded structure input liquid level transmitter. The product features a piezoresistive sensor with proven long-term stability and reliability, and a special digital compensation circuit housed in a robust stainless steel housing. It offers integrated construction, supports standard outputs, and cable options in multiple materials for a wide range of operating temperatures. Specifically, PL303 is mostly used for liquid level monitoring of refined oil products such as gasoline, diesel, kerosene, etc. PL303 is mostly used for liquid level monitoring of chemicals, such as methanol, ethanol, diesel exhaust fluid (DEF), diesel engine coolant, etc. These two level transmitters are also suitable for other environments with high requirements for wear protection, protection or explosion protection.
