Description

DESCRIPTION DERINSU 02 ANALYZER Technical Area The invention is the monitoring of the oxygen percentage during the nitrox diving cylinder filling phase and the filling process. After it is done, a device is used to control the oxygen percentage in the tube. It is related to the oxygen analyzer device. Prior Art In order for scuba diving people to do nitrox dive, the diving tube should be filled with nitrox air. They must be filled with their wife. In order to fill the cylinder, the air (21%) oxygen) by adding pure oxygen to the percentage of oxygen in the air. As a result of filling the diving tubes with nitrox mixture by increasing the rate of nitrox diving tube is being prepared.

Measuring the percentage of oxygen in the nitrox mixture and keeping it at a certain value required. Monitoring the percentage of oxygen while filling the Nitrox diving tube and control of the oxygen percentage in the tube even after filling requires an oxygen analyzer. nitrox dive tube without analyzer cannot be filled. Or if the tube is taken with the ready nitrox mixture prepared Checking the mixture in the tube is very important in terms of diving safety. is important. Dive tube control with analyzer for safe diving. Necessary information is written on the tube. Tube cannot be checked without analyzer and a safe dive will not be possible if the analyzer is not equipment.

Only the percentage of oxygen is shown on commercially available analyzers. Moreover some analyzers use disposable sensors after the life of the sensor is approximately 3 years. sent for recycling.

In the analyzers available in the market, the partial pressure of oxygen (1.3-1.4-1.5) It does not calculate the maximum operating depth and at the same time 1.6 The maximum depth is not shown by calculating over

For this reason, various improvements in the technique for filling nitrox diving cylinders have been made. has been made.

Diving computer oxygen amount, maximum depth, pressure etc. a system that displays information to the user contains. However, the invention cannot be used as an oxygen analyzer.

In the patent document numbered EP2233392A2, which is in the state of the art, a diver who calculates the pressure and dive time according to the gas and informs computer is mentioned. Maximum operating depth, nitrox gas A system that calculates and presents information such as the amount and pressure values to the user. contains. However, the invention cannot be used as an oxygen analyzer.

In the patent document numbered US10274390B2, which is in the state of the art, a tank pressure with integrated breathing gas analyzer and associated methods transmitter is mentioned. Tank pressure transmitter, one breathing gas a gas sensor detecting the component and a component from the detected constituent compile the read and send that constructor read to a dive over the air. contains a transmitter operated to transmit to the computer. However, in question The invention cannot be used as an oxygen analyzer.

When the nitrox diving tube techniques available in the technique are examined; maximum operation An analyzer that displays depth, partial pressure selection of oxygen, and sensor volt measurement does not exist. Maximum operation of the mixture in the Nitrox diving tube It also shows the minivolt value of the sensor connected to the device during measurement. development of a nitrox analyzer was needed.

Objectives of the Invention The aim of this invention is to determine the mixing ratio in the nitrox diving tube, the maximum of a nitrox analyzer that displays operational depth information to the diver. is realization.

Another purpose of this invention is to provide sensor minivoltage information, which expresses the life of the sensor. is the realization of a divergent nitrox analyzer.

Another object of this invention is oxygen fraction pressures between 1.3 - 1.4 - 1.5 ratios. offers the possibility of choice.
