Abstract
The utility model belongs to a marking device of methane sensor, which is used to the instrument and meter for calibrating the concentration of the detected gas, in particular to the accuracy and the zero position of the methane sensor, comprising an air bottle and an air sample bottle. The utility model has the advantages of compact structure, small size, light weight, convenient portability, and rapid calibrating.
Description
The utility model belongs to the instrument and meter to various detection concentration of methane gas, especially methane transducer is carried out the calibration device of precision measure.
This type of known device has only a kind of gas-sample bottle of splendid attire methane gas, promptly be precision that can only the calibrating instrument instrument and can not demarcate zero-bit, and stated accuracy is inaccurate, if instrument and meter need be demarcated zero-bit, then need carry an air bottle in addition, this to mapping work make troubles.
The purpose of this utility model is to overcome the deficiency that known products exists and design a kind of instrument and meter precision that can demarcate concentration of methane gas, can demarcate the methane transducer calibration device of these device zero-bits again.
This technical scheme is to be had only a gas cylinder to change gas cylinder into to be made up of for (2) two kinds air bottle (1) and gas-sample bottle by original.
The utility model is that calibration device has brought the many places advantage promptly can demarcate the new function of zero-bit being merely able to originally increase again on the stated accuracy basis.Improved stated accuracy thus, and be easy to carry again.
Accompanying drawing is a structural representation of the present utility model.
The schematic construction that has shown this methane transducer calibration device in the accompanying drawing, gas cylinder is to be made of air bottle (1) and gas-sample bottle (2), among them respectively splendid attire air and methane gas sample, and two bottles in tensimeter and decompressor variable valve are housed separately are connected on an end of flowmeter (3) by wireway (4), be used for measuring two bottles gas flow.Be simplified structure, the design be air bottle and gas-sample bottle shared a flowmeter (3), when surveying gas flow, the valve of opening respectively separately get final product, but can not open valve survey gas flow simultaneously.For the ease of carrying, two bottles of designs are less, and by fixed band two bottles of rigidity fixed.When reality is used this calibration device, realize by the cubing (5) that is connected on flowmeter (3) other end.
The utility model compact conformation, volume be little, in light weight, easy to carry, demarcate rapidly, if press maximum allowable working pressure calculating, fills once gas and can use continuously 50-80 minute.
Claims (1)
- The methane transducer calibration device, primary structure is made up of gas cylinder, on this bottle decompressor variable valve and tensimeter and flowmeter are installed, it is characterized in that gas cylinder is made of air bottle (1) and gas-sample bottle (2), they are connected on the flowmeter (3) by wireway (4).
