LIGO – RS485 FUEL LEVEL SENSOR

LIGO – RS485 probe length: (700mm-6000mm)

General description 

LIGO-RS232 / 485 fuel level sensor is researched and manufactured by SOJI ELECTRONICS. Equipment designed to monitor fuel levels in tanks, tanks, or reservoirs used in a variety of fields and applications. The measured values ​​will be transmitted to the external device through the supported interfaces: RS232, RS485 to connect to an external device.

Under certain conditions, the instrument can reach a high accuracy of up to 99.5%. There are several types of sensors currently used in the market to measure fuel levels using different technologies such as: the technology of magnetic switch device, the ultrasonic technology, Capacitive sensor (capacitive sensor). Among them, capacitive sensor technology is believed to achieve the best accuracy and longevity.

 

  • Highly accuracy up to 99.5%.
  • Length allow cut off up to 80 % of the initial length of the measuring probe.
  • Automatic recognize new length after cutting feature (this feature can be enable or disable by software on PC).
  • Wide range working temperature from -40°C – +85°C.
  • Screen filter is mounted on the measuring probe tubes to protect measuring probe electrodes from mud and water.
  • IP67 waterproof.
  • Advanced filter algorithm and temperature compensate.
  • Configuration,update firmware through software on PC .
  • Easy to install and sealed.
  • IP67 WATERPROOF.
