SOJI SP-RS232 FUEL LEVEL SENSOR

The second version of SOJI Capacitive Fuel Level Sensor Series, giving an complete solution for most popular GPS Trackers with digital output signal (RS232).

General description 

SP – RS232 is a special improvement line, a product of the research team of Soji fuel level sensor. Changes in the mechanical design help the sensor achieve high accuracy and durability.

  • Measurement accuracy up to 99.5%.
  • Length  reduction up to 80 % of the initial length of the measuring probe.
  • Automatic recognization of 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 compensation.
  • Configuration,update firmware through software on PC .
  • Easily to installing and sealling.

SOJI SF-RS232 FUEL SENSOR SIZE

Constantly changing fuel characteristics can dramatically impact the result of fuel measurements and cause confusion in statistics. For example, factors such as changes in temperature, vehicle motion – causing errors in fuel-level calculations of up to 30%.

In order to achieve greater works, SOJI SP-RS232 Capacitive Fuel Level Sensor uses algorithm to compensate the effect of these changes and guarantee unprecedented accuracy of 99.5% in all conditions.

Therefore, SOJI SP-RS232 Digital Fuel Level Sensor reduces maintenance and re-calibration needs with the ability to compensate for errors in initial calibration, an issue that affects 20% of installed sensors. It provides accurate statistics for fleet owners and builds trust for installation partners who can confidently deliver on promises of accuracy.

In compare to Technoton Dut-E Sensor, Soji gives an equivalent solution in terms of quality whereas cutting the cost to a half.

Apart from Analog Version, SOJI Fuel Sensor is also available in Analog and RS485 signal standard, giving customers more options to suit with current operating system. Find out more at: SOJI SP-AF Analog Fuel Level Sensor or SOJI SP-RS485 Fuel Level Sensor.
