The fuel level sensor is an additional equipment designed for continuous monitoring of fuel level in vehicles and in tanks. GL-TV AFD - sensor of capacitive type, which allows to measure fuel level in tanks and tanks of vehicles up to 3 meters deep. The fuel level sensor has a high resolution, less than 0.5 mm in level.
Versatility of the connection, both analog and digital inputs, good technical characteristics together with the original design solutions, prompted by the numerous experience of operation of various level sensors give the following possibilities:
- easy connection to any GPS tracker;
- resistance to mechanical and thermal stresses;
- quick and accurate sensor adjustment and tank calibration;
- visual diagnostics and adjustment of the sensor's operation with the help of graphs of fuel level and calibration.
Constructive and functional capabilities of the sensor:
• Fuel level monitoring in real time; |
• Controlling the temperature of the fuel; |
• Thermal compensation of sensor operation; |
• 5-pin mounting: increased reliability of mounting on the tank; |
• Auto fuel level delivery; |
• All-metal design: withstands extreme loads and is convenient in installation on thin-walled tanks; |
• Allows you to configure and configure the sensor without external power supply with the original GL-TVin device; |
• Support for any GPS trackers with analog (voltage or frequency) and digital interface RS-485; |
• Massiveness and strength of the construction protects the sensor from mechanical influences during operation; |
• Full galvanic isolation: provides reliable protection against surges in the car's on-board network, which guarantees long-term operation of the sensor; |
• Strong elongation wires, with thickened insulation; |
• Linear accurate fuel level measurements; |
