Liquid level detection device

The utility model relates to a liquid level detection device. Its characteristics are including the probe, and there is the through -hole as medium transmission path at vertical center of probe, and the front end of probe has the axial chimb, has the diaphragm in the axial chimb. There is the axial blind hole at the rear end center of probe, the aperture of axial blind hole is greater than the through -hole. The hole bottom of axial blind hole is flat, has the diffusion silicon core in it. Compressing tightly in the drill way of blind hole and emitting, it has the centre bore to compress tightly to emit. Even there is the display detecting head rear end, has amplifier circuit in the display, amplifier circuit is through the wire and pass and press the centre bore that emits to link to eachother with the diffusion silicon core. Adopt this kind of liquid level detection device, can eliminate and detect the sum of errors potential safety hazard. Be applicable to the liquid level detection of the liquid -state ch
