The thermometer overhaul on the industrial equipment should pay attention to what issues?

Bimetallic thermometer is very widely used, but we today is mainly about the bimetallic thermometer on the industrial equipment. Because of the bimetallic thermometer is a temperature measuring instrument, in order to guarantee the accuracy of the temperature measurement value, we should to check on a regular basis. Verification before the bimetallic thermometer, then, what are the problems need attention? We summarized the following two aspects: 1. The risk identification and reduction measures of a job before. Risk identification: remove the bimetallic temperature during installation time, may cause a gas leak, so the surrounding must pay strict attention to fire prevention. b。 Reduction measures: strictly abide by the terminal security rules, into the valve chamber and technology zone, cannot take fire, such as mobile phones must be turned off safety regulations. 2. Overhaul before a remove the thermometer to ensure will not affect the normal production, should contact the dispatch instructions, consent rear can work. B confirm the environment there is no risk factors ( Such as natural gas leaks) Remove by riot wrench. （ Note: the meter connector connection pipe wrench must be used, so as not to loose. ） C removed with a clean cloth or other items after the instrument interface block to live on the pipeline to avoid clutter.
