Product Description



Product overview
PL301 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 resservoir, 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 has got intrinsic safety certification, explosion proof certification and CE certification. After long-term aging time, PL301 has stable and reliable performance,It can adapt to the harsh environment outdors.
Features
Wide range application ,Long service lif ,Diffused silicon oil-filed sensor cel ,CE certificat ,Reinforcement cables optiona ,Intrinsically sate ,explosion proof
Precautions
1 When the pressure transducer is in danger of being submerged or submerged, please order the IP68 type pressure sensor with liquid level sensor outlet type, or consult.
2 The pressure transducer port thread of the flat membrane pressure sensor is limited to M20 × 1.5 or G1 / 2,3/4" Tri-
clamp, if you need other special threads, please feel free consult us .
3 When pressure sensor range is in the range of - 5 ~ 5kpa, the sensor uses a non-isolated silicon piezoresistive pressure chip, and the product can only measure non-corrosive gases,please consult us for more information.
4 When testing media has high temperature, please choosing our high-temperature pressure sensor, the radiator needed well ventilated,
We can make sensor 175ºC- 230ºC for special use ,please consult us or pressure sensor
5 Gauge pressure sensor with a range less than 450PSI are equipped with vents or vent cables to prevent the vents from being blocked, please sonsult us!
