Seismic bimetallic thermometer is what kind of filling oil? What's the difference?

Bimetallic thermometer is widely used in industrial equipment, petrochemical industry, hvac equipment, hot stove, incubator, etc. And industrial principle of seismic bimetallic thermometer is like ordinary bimetallic thermometer, for bimetallic thermometer meter is the main purpose of the oil filled, in order to pointer in vibration reducing relative change in the larger environment impact, so that we can effectively ensure the sensitivity of the thermometer. Seismic bimetallic thermometer used in vibration in the working environment. General seismic bimetallic thermometer filling oil has two kinds of silicone oil and glycerin, aseismatic function are the same, the difference is that the degree of low temperature resistant, silicone oil than glycerol good low temperature resistance, when using - environment is achieved 20 ℃, glycerin is crystallized, and silicone oil or maintain normal working condition. The advantage of seismic bimetallic thermometer is used in vibration environment, on-site display temperature, intuitive and convenient, safe and reliable, long life, fast reading. Should pay attention to clean up and check when using, regularly test the measured values.
