Description
Technical Field
The utility model relates to a throw-in type level sensor belongs to sensor technical field.
Background
The input type liquid level sensor measures the liquid level by utilizing the hydrostatic principle, and is an important application of the pressure sensor. It is suitable for the liquid level measurement of various media in petrochemical, metallurgical, electric, pharmaceutical, water supply and drainage, environmental protection and other systems or industries. By adopting a special cable with an air duct in the middle and a special sealing technology, the water tightness of the sensor is ensured, and the reference pressure cavity is communicated with the ambient pressure, so that the high precision and the high stability of measurement are ensured.
As shown in fig. 2, the conventional drop-in level sensor is composed of three parts: a pressure probe for welding the silicon piezoresistive oil-filled pressure core body on the shell; a membrane protective cap with a pressure inlet and a filter screen; a cable for electrical connection;
the current input type liquid level sensor mainly has the problem in two aspects: of the sensor
It cannot measure due to the influence of the external dimension
The level of the medium in the canister or tubule; the weight of the pressure probe and the diaphragm protective cap is light, and after the sensor is put into a deep medium, the weight of the pressure probe and the diaphragm protective cap cannot ensure that a product and a cable are in a vertical state, so that errors can be caused in the measured liquid level height of the medium. In most applications, the position of the sensor inserted into the medium cannot be visually observed by the user, and therefore, the length of the cable extending into the medium can be used as the depth of the level measurement of the sensor. Thus, if the product or cable is not vertically sagging, measurement errors can be introduced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a throw-in level sensor to solve above-mentioned technical problem.
In order to realize the purpose, the utility model adopts the following technical scheme:
the utility model provides a throw-in level sensor, includes pressure probe and balancing weight, the balancing weight is cylindric structure, and balancing weight one end is sealed toper structure, and the other end is equipped with the internal thread, pressure probe's one end connecting cable, pressure probe's the other end and balancing weight threaded connection.
Preferably, the level sensor has a size of
Compared with the prior art, the utility model has the advantages of it is following: the utility model discloses a throw-in level sensor's external diameter is littleer, can use at
In the liquid level measurement of the small tank or the thin pipeline, the application range of the liquid level sensor is wider, and the cost of the pipeline is reduced; the utility model discloses a throw into formula level sensor's balancing weight, when the sensor was thrown into the measured medium, can keep vertical state, improved measuring accuracy.

Detailed Description
The invention is explained in further detail below with reference to the figures and the embodiments.
As shown in fig. 1, a throwing type liquid level sensor comprises a pressure probe 1 and a balancing weight 2, wherein the balancing weight 2 is of a cylindrical structure, one end of the balancing weight is of a sealed conical structure, an internal thread is arranged at the other end of the balancing weight, one end of the pressure probe 1 is connected with a cable 3, and the other end of the pressure probe 1 is in threaded connection with the balancing weight 2. The size of the liquid level sensor is
The utility model discloses adoptThe external dimension of the sensor is made by using a silicon piezoresistive core body with smaller dimension
In order to ensure that the weight of the pressure probe and the diaphragm protective cap is heavy enough, the diaphragm protective cap is improved into a counterweight block with a certain weight. Thus, the product after being put into the device can be ensured to be in a vertical state.
The foregoing is a preferred embodiment of the present invention, and for those skilled in the art to understand the teaching of the present invention, the changes, modifications, replacements and variations to the embodiments will still fall within the protection scope of the present invention without departing from the principle and spirit of the present invention.
