Abstract
The utility model provides an antifouling and anticorrosive liquid level sensor which adopts the structure that a semiconductor foil gauge a transmitter and a casing of a sensor are arranged in an anticorrosive nonmetallic outer sleeve of which the lower end is connected with a soft liquid bag filled with special liquid. Therefore, the liquid level sensor can be conveniently and reliably used for measuring the liquid level of various kinds of corrosive liquid, the pressure of various kinds of gas and the liquid level of various kinds of turbid liquid which comprises a plurality of impurities.
Description
The utility model belongs to a kind of measuring liquid level that is used for, the antifouling anti-corrosion type liquid level sensor that air pressure is used.
The existing semiconductor transducer that is used for measuring liquid level and air pressure has corrosive gas in measurement, liquid is stopped or during impure more mixed liquor, is prone to the corrosion or the obstruction of sensor, so that cause in the measurement than mistake, simultaneously, cause inconvenience, limited usable range to use.
The purpose of this utility model provides a kind of easy to use, antifouling anti-corrosion type liquid level sensor that have wide range of applications and uncorruptible.
The utility model is achieved like this, with nonmetal overcoat of device on conventional semiconductor foil gauge and transmitter, the sensor outer housing, an end of overcoat by external thread fixedly connected in the other end of spiral shell mosquito connect the towed flexible barge that dedicated liquid is housed.
Concrete structure of the present utility model is provided by the following drawings and embodiment.
Accompanying drawing is a structure cut-open view of the present utility model
With reference to accompanying drawing, nonmetal overcoat (6) assembles and is fixed on foil gauge and converter (4) sensor outer housing (5), lead (7) is connected overcoat (6) and sensor upper end, the lower end of overcoat (6) connects the towed flexible barge (1) that has special-purpose liquid (2) by the lower end wringing fit of the outer spiral shell mosquito (8) of the fixedly connected ring of internal thread (3), and the liquid capsule adopts anti-corrosive properties elastomeric material or other flexible material to make.
When surveying liquid level, this sensor is placed test solution, because the pressure that liquid level difference produced between sensor placement location and the liquid level promptly acts on liquid capsule (1), be sent to semiconductor gauge and transmitter (4) by special-purpose liquid (2) in the liquid capsule, the change hurdle is into electric signal, again by lead (7) output.
When surveying gaseous tension, only need this sensor vertical fixing in gas circuit.Can survey the pressure of gas in the promoting the circulation of qi road, its principle is identical when surveying liquid.
The utility model can make things convenient for, be used for reliably the barometric surveying of various corrosive liquids liquid levels, corrosive gas, and measure accurately, corrosion or latch up phenomenon can not take place, and also can be widely used in the measurement that the various dirts that contain a large amount of impurity are lost the liquid measure of fluid and had the powdery fine granularity solid of good fluidity simultaneously.
Claims (2)
1, a kind of antifouling impregnating fluid level sensor, it comprises semiconductor gauge and transmitter (4) outer sensor shell (5), it is characterized in that semiconductor gauge and transmitter (4), the end that sensor outer housing is equipped with a nonmetal overcoat (6) overcoat is fixedly connected by external thread (3), and the other end of internal thread (8) connects the towed flexible barge (1) that special-purpose liquid (2) are housed.
2, antifouling anti-corrosion type liquid level sensor as claimed in claim is characterized in that towed flexible barge (1) adopts anti-corrosive properties elastomeric material or other flexible materials to make.
