Why industrial bimetallic thermometer oil filled?

Industrial bimetallic thermometer is a member of the bimetallic thermometer, it can directly measure - 50 ℃ ~ + 500 ℃ temperature instrument on the site. Our common industrial bimetallic thermometer is used to distinguish to the environment, the common radial, axial and bimetallic thermometer three universal type. In the use of the environment under the condition of strong vibration, oil is filled in the header. So why oil filled? In fact oil charge is for damping effect. So the oil filled thermometer is also called seismic thermometers. Yes it works from the instrument internal seismic of silicone oil filling or glycerin, which can effectively overcome the mechanical vibration of pointer jitter. On the design principle and structure of a waterproof, corrosion resistance, vibration resistance, intuitive, easy reading, no mercury pollution, durable and other characteristics, widely used in petroleum, chemical industry, machinery, ships, electricity, textile, printing and dyeing and other industrial and scientific research departments. The main characteristic of bimetallic thermometer is used in industry: ( 1) Site display temperature, intuitive and convenient, safe and reliable, long life; （ 2) Many kinds of structure forms, can meet different requirement, no mercury pollution, easy reading, strong shock resistance; （ 3) Protection is 1 gr18ni9ti stainless steel and molybdenum titanium tubes, pressure and corrosion ability;
