The shapes of the grooves formed in the main body 210 and the grooves formed in the cover 220 may correspond to each other so as to be in close contact with each other. Even when the body portion 210 and the cover 220 are tightly coupled, a spatial gap may be formed between them or a vertical gap may occur due to a difference in length of the coupled portion.

In addition, the silicone-type packing rubber 215 is inserted into the gap between the body part 210 and the cover 220 or the gap generated when the body part 210 and the cover 220 are coupled to the measuring unit 200. ) can improve the sealing power. By combining the packing rubber, it is possible to block fluid and dust from flowing into the measuring part of the sensor, and to obtain a waterproof level higher than an appropriate standard.

In this case, the temperature sensor 250 can be maintained at the same position regardless of whether the first substrate 230 is detached or not, and only one end of the temperature sensor line 251 can be detached.

The cable 201 may be conceptually divided into one structure in the body part 210, but may be physically separated and separated from each other.

When the cable 201 is a separate component physically separated from the body portion 210, a gap may occur between the cable 2010 and the body portion 210. In this case, the packing rubber 215 may be brought into contact to block the gap. The packing rubber 215 may serve to block a fluid path between the cover 220 and the body portion 210 and at the same time block a fluid path between the cable 201 and the body portion 210. .

The cable 201 may be classified as a measurement unit cable or a communication unit cable by internally dividing an arbitrary length of the entire length. The measurement unit cable and the communication unit cable may be configured in a detachable form. Each detachable cable may be defined as a subcable, but is not limited thereto. In this way, it is possible to change the type of sensing unit while repeatedly using one communication unit, thereby improving economic feasibility and convenience.

In addition, the cable 201 may be a plurality of cables, and the number of cables may be differently defined according to the type and number of sensors.
