LIGO-AIR Fuel Level Sensor is developed and manufactured by SOJI Electronics JSC. The device is designed to measure the level of liquid fuel and other non-conductive liquids in vehicle tanks and stationary fuel storage, applicable in different fields. Equipped with advanced Bluetooth Low Energy technology, LIGO AIR enables seamless, real-time data transmission without the need for complex wiring and is easy to install.
The purpose of creating a new product was to satisfy the increasing demand in the transport telematics market for improved reliability of the design, data, and ease of installation. Unlike its predecessors, the wireless fuel level sensor helps minimize the risk of signal wire tampering.
In addition, the heavy-duty metal structure helps increase protection against environmental factors such as dust, moisture, vibration, and high temperature conditions. This ensures that the LIGO AIR sensor maintains stability, durability, and an operational lifespan equal to or even greater than that of wired sensors.
Key features:
– High accuracy up to 99.5%.
– By utilizing directional antenna technology, the sensor achieves a communication range up to 5 times greater than that of typical market-available sensors.
– With ultra-low power consumption (9uA in working mode and 4uA in storage mode), the sensor ensures longer battery life and reduced maintenance.
– Can be optionally shortened or extended up to 6000mm.
– Wide operating temperature ranges from -40°C to +85°C.
– TX power up to 19.5dBm (LIGO AIR PRO).
– Battery capacity up to 3600mAh (optional) helps extend sensor’s battery life.
– Built-in accelerometer.
– Built-in 32MB EEPROM for data logs (Continuously stored for a minimum of 90 days) and setting logs (Maximum 500 logs).
– Built-in Anti-mud oil filter and anti-vibration springs.
– IP69K waterproof standard.
– 8-10 years of battery life.
General applications
– Trucks, excavators, heavy construction machines…
– Marine vessels and electric generators.
– Off-highway machinery including high-temperature & vibration environments.
– Industrial oil storage tanks or stationary storage tanks.
