Description of hydrostatic level sensor

PL301 capacitive water diesel tank level sensor with CE&ISO series fuel oil level sensor adopts high performance diffused silicon piezoresistive pressure sensor as the measuring element series pressure transmitter is a high reliability, high stability, high accuracy and small volume level transmitter with part structure. Widely used in measurement liquid pressure and height in small inside diameter pump as well as level height of liquid reservoir, such as water, oil and mild corrosive liquid.

We offer special ventilate cable that resistance to abrasion, oil, acid & alkaline and strength according to on-site environment.

PL301 capacitive water diesel tank level sensor with CE&ISO has got intrinsic safety certification, explosion proof certification and CE certification.

After long-term aging time, PL301 capacitive water diesel tank level sensor has stable and reliable performance, It can adapt to the harsh environment outdoors.
