Abstract

The invention discloses an ultrasonic multifunctional gas monitoring instrument capable of being held by a hand for inhaling gas for a test. The instrument comprises a shell. A gas inhaler and a sensor shell is arranged at the top of the shell. An ultrasonic sensor is arranged in the inner cavity of the sensor shell. A circuit board is arranged in a gas test cavity. A pre-amplifying circuit, a band pass filter, a secondary amplifying circuit, a frequency mixer and a power drive circuit are sequentially arranged on the circuit board. The pre-amplifying circuit is electrically connected with the ultrasonic sensor. One side of the shell is provided with a headphone interface which is electrically connected with the power drive circuit. An auxiliary handlebar is arranged at the bottom of the shell. A hanging rope is arranged at the bottom of the auxiliary handlebar. The ultrasonic multifunctional gas monitoring instrument is convenient to use, high in sensitivity, convenient to carry and to be placed in hands for the operation, more precise in gas test, and therefore the work efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a hand-held ultrasonic multifunctional gas monitor for gas inhalation and detection. Background technique [0002] At present, a large number of pressure vessels for storing and transporting compressed gas are used in industry and life, such as cylinders, gas tanks, gas pipelines, and airtight chambers. Due to various reasons, the container will produce leaks and gas leakage will occur. It is estimated that the average loss of compressed gas due to leakage accounts for about 40% in industry. Leakage will not only cause a waste of energy, but also pollute the air if it is a harmful gas. Traditional leak detection methods, such as absolute pressure method, differential pressure method, bubble method, etc., are complex to operate and require high technical personnel, and do not have real-time performance. At present, the principle of ultrasonic waves generated by leaks is w...
