Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1, 2, and 3, an embodiment of the present application provides a sensor with a sealing function, which includes a housing 1, a front cover 2 and a rear cover 4 are respectively connected to two ends of the housing 1, and the front cover 2, the rear cover 4, and the housing 1 form a sealed space.

The outside at 1 middle part of shell is connected with first mounting thread 5, twists this sensor on the outside container wall or interface position through first mounting thread 5, the outside that shell 1 is close to 4 one ends of tail-hood is connected with boss 6, one side that tail-hood 4 was kept away from to boss 6 is connected with sealing washer 7, fixes this sensor installation back through first mounting thread 5, and sealing washer 7 plays sealed effect, makes 5 parts of the first mounting thread of this sensor can not reveal liquid or gas to guarantee to use reliably, dismantle easy maintenance.

The installation mode of this application except threaded connection mode, can also be clamp connection mode or flange joint mode.

The inside connection of shell 1 has PCB board 8, be connected with probe module 9 and circuit module 10 on the PCB board 8, the inside sealing of shell 1.

The principle of the sensor is that an object is detected by the sensor probe module 9, when the object (metal or nonmetal or liquid level, etc.) reaches the sensor sensing head part, the internal circuit of the sensor determines whether the threshold value set by the chip circuit is reached according to the change of the frequency, capacitance value, inductance value or sound wave of the object of the sensor probe module, so as to judge whether the object exists.

On the basis, the shell 1, the first mounting thread 5 and the boss 6 are of an integrated structure, and the integrated structure is good in sealing performance.

On the basis, the boss 6 is far away from one side of the tail cover 4 and is provided with a groove, the sealing ring 7 is arranged in the groove, the sealing ring 7 is embedded in the boss 6 of the sensor shell 1, and liquid or gas is prevented from leaking to the sensor, so that the use reliability is ensured, and the disassembly and maintenance are convenient.

On the basis, connect through gluing between PCB board 8 and the shell 1 for 1 internal seal of shell, the encapsulating between PCB board 8 and shell 1, PCB board 8 and the electronic components on it all are fixed through gluing, makes 1 inside confined space that forms of shell, need not beat sealed glue or raw material area when the installation, can not damage this sensor after the dismantlement, makes this sensor can repetitious usage.

On the basis, the inside of tail-hood 4 is connected with connector 13 through gluing, connector 13 is close to one of PCB board 8 and serves and be connected with connecting wire 12, the other end welding of connecting wire 12 is on PCB board 8, connector 13 keeps away from one of PCB board 8 and serves and be connected with interface 14, makes this sensor and outside carry out signal transmission through interface 14.
