Abstract
A sensing device can detect material depth, liquid-level, and temperature. The sensing device has a probe, a control module, a volume sensing module, a thermal sensing module, an output module, and a power module. The probe has two material electrodes connected to the volume sensing module and a thermal electrode connected to the thermal sensing module. A rated voltage is applied at the material electrodes based on radio frequency admittance. A current deviation of the material electrodes is obtained by the volume sensing module, and calculated via the control module by material characteristics to obtain a correct storage amount of material. A temperature at each material depth is correctly detected by the thermal electrode. Steel cable is used as the material of the material electrodes of the probe to detect material depth or liquid level with high impact resistant ability.
