Problems solved by technology

[0002] The DO sensor is a sensing device used to measure the amount of dissolved oxygen in water. During use, the sensor head needs to be inserted into the water body. When the user stands on land and detects, the water body near the edge Affected by the land and the dissolved oxygen in the overall water body will be different, the sensor head needs to be extended farther, because the transmission line is soft, it will cause inconvenience in use, and the use of support rods will also cause inconvenience in operation and reduce efficiency, while Entering the water body by boat will increase the amount of dissolved oxygen in the water body, which is time-consuming and laborious, and the cost of detection will increase. Taking water samples will also cause changes in the amount of dissolved oxygen. However, the existing DO sensor cannot solve the above problems. Therefore, The invention proposes a DO sensor with strong anti-interference stability

Abstract

The invention provides a DO sensor with strong anti-interference stability, comprising a sensor body, a transmission line and a sensor head, the sensor head is connected with the sensor body through the transmission line, and a support and adjustment rubber sleeve is fixedly sleeved on the transmission line, A protective sleeve is fixedly sleeved on the sensor head, and the protective sleeve is fixedly connected with the support and adjustment rubber sleeve. The design of the DO sensor with strong anti-interference stability is reasonable, and the transmission line is fixedly sleeved with a gas supply glove. Tube and support adjustment rubber sleeve, when in use, the air supply handle sleeve provides air for each branch air channel in the support adjustment rubber sleeve, so that the transmission line can be gradually straightened, and the shape of the transmission line can be adjusted as required, so that the transmission line can be adjusted. The sensor head can be more conveniently and stably extended to all parts of the water body to be detected, thereby improving the convenience of use.

Description

technical field [0001] The invention belongs to the technical field of sensor production, in particular to a DO sensor with strong anti-interference stability. Background technique [0002] The DO sensor is a sensing device used to measure the dissolved amount of oxygen in water. During use, the sensor head needs to be inserted into the water body. When the user stands on the land to detect, close to the water body at the edge Affected by land and the dissolved oxygen in the overall water body will be different, and the sensor head needs to be extended farther. Because the transmission line is soft, it will cause inconvenience to use, and the use of support rods will also cause inconvenience in operation and reduced efficiency. Entering the water body by boat will increase the dissolved oxygen content of the water body, which is time-consuming and labor-intensive, and increases the detection cost. Taking water samples will also cause changes in the dissolved oxygen content. ...
