Fuel Level Sensors (FLS Series)
Reliable reed switch technology inside a sealed tube. The magnetic float triggers switches to output a stable resistance, voltage, or current signal. IP67 Rated.
FLS-H Series (Heavy Duty)
Designed for heavy trucks and off-road vehicles. Rugged aluminum header with integrated connector.
- Material: Aluminum Alloy
- Mounting: Bayonet / Twist Lock
- Output: 0-190Ω / 4-20mA / 0-5V
- Length: 200mm to 1000mm
FLS-L / S5 Series
Cost-effective solution for light trucks, generators, and marine. Made of SUS304/316 Stainless Steel.
- Material: SUS304 / SUS316
- Mounting: SAE Standard 5-Hole
- Resolution: 10mm – 21mm
- Temp: -40°C to +85°C
FLS-S Series
Designed specifically for GPS Fleet Management. Compatible with vehicle trackers.
- Voltage Input: 10-32V DC
- Output: 0.5-4.5V / RS232 Option
- Mounting: SAE 5-Hole or BSP Thread
- Feature: High Stability Signal
AdBlue (DEF) Urea Sensors
Ad Series: Designed for SCR systems to reduce NOx emissions. AdBlue freezes at -11°C, so our sensors integrate a coolant heating circuit.
- ✔ Material: 316 Stainless Steel (Corrosion Resistant)
- ✔ Integrated Functions: Level + Temperature + Heating + Suction/Return
- ✔ Filter: Optional filter foot to protect the pump
- ✔ Connector: TE / Delphi / Deutsch available
CLS Capacitive Sensors
Unlike reed sensors, the CLS series uses capacitance technology for continuous, high-precision measurement (Resolution < 1mm). Best for tall tanks or when length customization is needed.
Key Feature: Cut-to-Length
Distributors can stock long units and cut them to size. Calibration is done via external calibrator.
Specifications
- Length: 200mm – 1500mm
- Output: 0-5V / RS485 / RS232
- Accuracy: < 1.0%
- IP Rating: IP65
