Into the thermometer to visit quartz tube the working principle of the thermometer

Quartz tube in the thermometer measurement, to bring green liquid, gas phase showed in red,, because of the large liquid gas phase display contrast indicates bright and clear, so more advantageous for remote operation and night patrol, is to use the latest technology at home and abroad to develop. And it is widely used in petroleum, chemical industry, electric power, metallurgy, etc all kinds of transparent liquid containers and boiler, such as water, gas, liquefied gas, liquid ammonia, propane, propylene, aromatics, acid and other oil products and chemical raw materials of liquid level measurement. At the same time for the two kinds of different medium density interface measurement, can choose three color interface quartz tube thermometer. Three color quartz tube thermometer interface is designed by using the principle of buoyancy and the proportion difference, two small float suspended in the medium separating part, due to float in black, upper and lower part of the liquid color is different, so the display eye-catching. So as to solve the has plagued in petrochemical process distinguish between two kinds of hybrid medium interface problem. It is the most ideal at home and abroad direct-reading quartz tube thermometer. The material most of the thermometer was glass, easy to maintain, digital display characteristics accurately, but it also has obvious disadvantages, such as fragile, not high temperature resistant, not resistant to acid and alkali, etc. , but now in addition to glass thermometer, quartz tube thermometer has been widely used.

instructions: (1) when using, should slowly open the valve into the liquid, and glass tube preheating 20 ~ 30 minutes, after a certain temperature, can all open on both ends of the valve into the water or other medium. (2) often pollution in use process requirement, to avoid fouling corrosion blocking channels, appear false water level phenomenon. (3) when due to accidental damage, with the help of the instrument will handle cock up and down up and down the plug turns 90 & deg; Containers within the medium, prevents the exodus to continue at this point, can replace the damaged parts (4) packing gauge after conventional transportation tools are available, and but should avoid violent vibration and snow and rain erosion directly. 0 ~ 5) should be on temperature 40 ℃, relative humidity is not more than 80% of the dry ventilated indoor, outdoor air should not gauges containing corrosion medium. 6. Must be installed vertically, the vertical deviation degree should be less than 3 & deg; 。 Between 7 and containers should be equipped with stop valve, in order to cleaning and maintenance with dielectric isolation. Today, according to the medium situation should be conducted on a regular basis of ontology pipe cleaning, removal of tube of sundry.
