Why a body surface temperature and pressure oil filled?

Temperature and pressure of a surface from German technology, can measure pressure, and temperature can be measured, a table is multi-purpose. Factories manufacturing process: from welding leak & rarr; Full pressure & rarr; Proofreading value & rarr; The finished product assembly & rarr; Value for inspection & rarr; The packing factory. In the process of using, we sometimes encounter to a body surface temperature and pressure of oil filled in the header, then the temperature and pressure of a surface why oil filled? Model: WHT - 12 ss type: temperature and pressure of a surface structure: the axial type material: stainless steel, can waterproof surface diameter: 69. Sheath maerial of 5 mm diameter: 6. 35 mm stainless steel connections: 1/4 & quot; NPT heat pipe length: 38 mm teeth temperature range: 0 - 120 ℃ pressure range: 0 - 16 bar: precision temperature: + / - Pressure: 2% + / - 3 - 2 - Above 3% in the temperature and pressure of a surface, for example. Its surface compared with the ordinary temperature and pressure difference in all over the structure of the seal, but also save a filling oil hole. If we need to provide header oil filled, only need to remove the oil plug, can give its header oil filled, after completion of oil filled with filling oil plug line; If we don't need to header oil filled, you can directly use. Normally, we will according to the need of the actual situation, to its header filled with silicone oil or glycerin, this mainly have the effect of shock.
