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.
