Epsilon series sensors measure fuel levels in vehicle tanks with an error margin of no more than 1–2%. This accuracy makes it possible to detect fuel refills and drains as small as 5–10 litres for trucks and 10–20 litres for heavy machinery.
Unlike standard resistive-type fuel sensors, capacitive sensors are fully electronic and contain no moving parts, ensuring high accuracy, long-term stability, and reliable operation.
All Epsilon series sensors feature a modular design: the measuring head can be mounted or removed independently of the fuel probe. This allows for quick and easy replacement of the measuring head, if necessary, without recalibrating the tank. The design also enables simple installation, even in hard-to-reach locations.
All Epsilon sensors are installed partly inside the fuel tank and partly near the tank, i.e., in potentially explosive environments. Therefore, all Epsilon sensors are equipped with certified intrinsic safety barriers (protection type 1Ex for Epsilon ES and EN, and 0Ex for Epsilon EZ). Explosion-proof protection is confirmed by relevant national and EU certificates.
Our support service provides technical assistance to customers worldwide. Experienced professionals offer guidance on the installation, configuration, and operation of Epsilon fuel level sensors.
Our training program is designed to help users develop the necessary skills and gain first-hand experience in installing and maintaining our products.
Epsilon-ER2-BLE Wireless Fuel Level Sensor is designed to measure the level of fuel and other non-conductive liquids in vehicle tanks and stationary fuel storage facilities.
Epsilon-ER2-BLE can be used with external data acquisition devices (such as GPS monitoring equipment) that support BLE (Bluetooth Low Energy) technology — a Bluetooth specification optimized for ultra-low power consumption.
Key Advantages:
High sensor resolution, excellent linearity, and temperature stability;
Built-in calibration table for direct data output in liters;
Galvanic isolation to protect the sensor head from power surges;
Robust monolithic design;
Adjustable probe length from 15 to 300 cm;
Easy installation — the probe can be shortened with a standard hacksaw;
The sensor is used for continuous non-invasive, digital, automatic measurement of LPG level and other liquids such as water, chemicals.
Sigma ULB measures the level mainly in aboveground stationary cylindrical metal tanks from 10 cm up to 4 meters depending of the liquid density.
The sensor has measurement error from 5% up to 1 mm depending on the model. Can be installed in the 0 explosive zone.
The sensor is a device that consists of one or two ultrasonic emitters / meters connected to a signal converter.
The converter is connected to intrinsically safe unit. The barrier is not included in the installation set and supplied as a separate, independent product.
Sigma ULB has RS 232, RS 485 output and can be easily connected to GPS tracker, PC, notebook, smartphone or digital indicator
