Abstract

The invention provides a two-point-type liquid level sensor for measuring the rocket storage tank volume loading liquid level. A liquid level probe assembly senses changes of the loading liquid level by means of characteristics of photoelectric signals in a water medium, and the liquid level probe assembly is connected to and installed on a sensor body through a fastener; a protective cover is connected to the sensor body through a screw for protecting the liquid level probe assembly; a cable assembly and a waterproof sealing socket are connected to achieve the signal output function of the sensor. The working medium is water, the sensor is mainly used for measuring the important liquid level point of loaded volume, obtained after production, of a rocket storage tank, liquid level signals are provided for a volume measuring system, and the characteristics of the photoelectric signals in the water medium can be used, so that the signals of the loading liquid level point are obtained, and the sensor for measuring the rocket storage tank volume loading liquid point has the advantages of being good in machinability, reliable in working, high in measuring precision, convenient to use and the like.

Description

technical field [0001] The invention relates to a two-point liquid level sensor used for measuring the volume filling liquid level of a rocket storage tank. Background technique [0002] Volume measurement of rocket tanks is an indispensable link in the production of liquid propellant rocket tanks. The accuracy of the volume value of the storage tank directly affects the accuracy of the filling accuracy of the rocket and the accuracy of the telemetry data, and directly affects the carrying capacity and guidance accuracy of the rocket. [0003] The working medium used to measure the liquid level of the rocket storage tank is water, and the commonly used capacitive liquid level sensor is not suitable for the liquid level measurement of the water medium, with poor accuracy and low reliability. Contents of the invention [0004] The object of the present invention is to provide a two-point liquid level sensor for measuring the filling level of the volume of the rocket sto...
