Slurry density sensor

Abstract

The invention discloses a slurry density sensor, which comprises a standard measurement bucket (1), a sensor A (2), a sensor B (3) and a foot stand (4). The lower end of the standard measurement bucket (1) is provided with a cement slurry inlet (5), and the upper end of the standard measurement bucket (1) is provided with a slurry outlet (6). A screw mounting opening A (7) and a screw mounting opening B (8) are formed at the interval of h on the sidewall of the standard measurement bucket (1). Density is calculated according to a formula. The slurry density sensor changes the selection of a reference height in the prior art and uses a fixed height so as to greatly improve the sensitivity and accuracy of the density sensor and more accurately and timely reflect a density parameter of slurry, simultaneously reduces the diameter of the standard measurement bucket so as to increase the flow velocity of the slurry, prolong the service life of the sensor and further reduce sensor replacement and disassembly times and the production cost, and has a wide application range.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a slurry density sensor. Background technique [0002] A sensor is a detection device that converts the information to be detected into electrical signals or other required forms according to certain rules. At present, there are many types of density sensors, but few are used in large-scale construction sites, such as rock The detection of slurry density and pressure and the detection of slurry flow in soil engineering are mainly due to the following reasons: ① The working environment at the construction site is extremely harsh, which affects the normal operation of the sensor, and the service life of the sensor is relatively short; ②The detection target is generally cement slurry, additive mixture, etc., which are highly corrosive and easy to solidify, which will affect the performance of the sensor; ③Many sensors need to be replaced and disassembled, and the use cost is relativ...

Problems solved by technology

[0004] At present, the detection of slurry density in engineering is mainly through the distance between the sensor and the slurry outlet plane ( is calculated with the cement slurry outlet plane as the datum plane), such as image 3 shown, according to to get the density of the slurry , but in actual production, due to the characteristics of the slurry, it has a certain viscosity and poor fluidity, and the actual height ratio more column of slurry, so it should actually follow is calculated, but It is greatly affected by the external environment, such as temperature, flow, etc., and It has not been calculated and tested, so the accuracy of the current detection of slurry density in engineering is poor
