Capacitive Oil Level Sensor
- PRODUCT DETAIL
Capacitive oil level sensor is the principle of the use of positive and negative electrodes filled with liquid medium formed by the capacitance with a linear change in the liquid level, The amount of change in capacitance (that is, the level of change) into a standard electrical signal output. Product core components using a highly integrated special capacitance measurement chip, after accurate temperature compensation and linear correction, with high precision, high stability and continuous measurement, etc., Has a strong independence.
Independence: directly through the measurement of fuel tank fuel to obtain fuel consumption, not on the oil system / pipeline caused any effect and impact.
Convenience: can be fixed by means of flanges, easy to operate.
Unique: With the range from the truncation function, the user can re-calibration through the button, the digital output can also be equipped with debugging software.
Self-tuning: the sensor can be based on different tank size, the scene to adjust the range and the implementation of the installation; sensor to increase the temperature compensation function, automatically correct due to the different temperature error.
Safety: direct replacement of the original car fuel gauge, no need to re-install the tank in the tank capacitance sensor, electronic cabin with explosion-proof design and through the explosion-proof certification.
Stability: no mechanical activities, mature and stable circuit structure and high quality components will make the sensor for several years without the need for replacement.
The core components of the product using advanced RF capacitor detection circuit, after 16-bit microcontroller precision temperature compensation and linear correction, into a standard electrical signal (usually 4 ~ 20mA). Optional HART, CANBUS, 485 communication protocol for system configuration. a full range of transmitters are self-calibrating, the user can calibrate the "zero point" and "range" with two keys or two leads to suit the different requirements of various complex locations.
