Embodiment 1

[0030] Such as figure 1 , Figure 5 and Figure 7 As shown, a sensor assembly with bottoming detection includes a sensor assembly 1, the lower part of the sensor assembly 1 is fitted with a slip ring 2 that can slide along the axis of the sensor assembly 1, and the bottom of the slip ring 2 An impact part 4 is provided, and the sensor assembly 1 includes an acceleration sensor.

[0031] The lower part of the sensor assembly 1 and the upper part of the slip ring 2 are provided with a limit snap ring 5 .

[0032] The sensor assembly 1 further includes a dielectric constant sensor, a temperature sensor, a pressure sensor or / and a Ph value sensor combined with the acceleration sensor.

[0033] The slip ring 2 is made of stainless steel.

[0034] The acceleration sensor is piezoelectric crystal, piezoresistive or capacitive.

Embodiment 2

[0036] Such as Figure 2 to Figure 7 Shown is another embodiment of the present invention. It is different from Embodiment 1 in that: it also includes a sensor assembly bracket 3, the upper part of the sensor assembly bracket 3 is fixedly connected with the lower part of the sensor assembly 1, and the sensor assembly bracket 3 and the slip ring 2 are slidable socket.

[0037] The periphery of the sensor component bracket 3 is evenly distributed with hollows, and the lower part of the sensor component bracket 3 is provided with a limit buckle 5 matching with the upper component of the slip ring 2 .

[0038] The working principle of this embodiment is as follows: when the present invention is put into the liquid material, it falls at a constant speed through the traction line, and when the present invention is in normal fall or suspended in the liquid state, the slip ring 2 is suspended on the sensor assembly bracket by gravity 3, due to the function of the limit buckle 5, the...

Abstract

The invention relates to the field of a sensor technology, and particularly to a sensor assembly with bottoming detection. The sensor assembly with the bottoming detection comprises a sensor assembly and is characterized in that a slip ring capable of sliding along the axis of the sensor assembly is sleeved on the lower portion of the sensor assembly, the bottom of the slip ring is provided with a bump part, the sensor assembly comprises an acceleration transducer, limit clasps are arranged on the lower portion of the sensor assembly and the upper portion of the slip ring, and the sensor assembly further comprises a dielectric constant sensor, a temperature sensor, a pressure sensor or / and a Ph value sensor which are combined with the acceleration transducer. The sensor assembly with the bottoming detection has the following advantages: clear abrupt change signals can be obtained by the sensor assembly for accurately determining whether bottoming exists so that measuring interference caused by such factors as material viscosity, dielectric constant changes, or a loose and soft bottom and the like are avoided.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a sensor assembly with bottom detection. Background technique [0002] In industrial production, it is often necessary to measure various parameters of liquid materials. After the sensor enters the liquid material, it is necessary to know whether the sensor has reached the bottom of the liquid material container. In many cases, due to the complexity of the liquid material, accurate measurement is required. Detecting bottoming conditions is not easy. For example, in the process of oil extraction, what is collected is a mixture composed of crude oil, water, and sediment. After the mixture is injected into the storage tank, the medium in the storage tank will gradually separate to form air, crude oil layer, pure water layer, and sediment. layer, where the silt layer will usually be at the bottom. When the suspension sensor used to detect the medium descends to the bottom of the st...
