The anti-corrosion metal thermometer advantage sex

Anti-corrosion metal thermometer is a kind of suitable for measuring the temperature field testing instrument, can be used to directly measure the liquefaction, the temperature of the gas. Compared with other temperature measurement meter products, anti-corrosion metal thermometer precision level is 1. Level 0, instrument shell with anti-corrosion materials, up to 200 ℃, the temperature tolerance to low - 40℃。 Flange structure, double o-ring seal, the anti-corrosion, waterproof properties is good.

instrument protective pipe welding using automatic argon protection, weld a solid, small intergranular corrosion. Dial is aluminium oxide printing plate, the surface clear aesthetic appearance. A pointer is adjustable. Metal thermometer axial, radial and universal type header type selection, etc. Metal thermometer sheath maerial length can be customized according to customer needs.

metal thermometer is the use of two different metal expansion degree during temperature change of the principle of work, to improve the temperature measuring sensitivity, is usually made of metal spiral coil shape. When multi-layer metal temperature change, the layers of metal expansion or contraction, makes the spiral coil rolled up or let go. As a result of the spiral coil end fixed and the other end connected to a free rotating pointer, therefore, when the bimetallic strip feel the temperature change, Pointers can be on a circular dividing scale to indicate the temperature.

this instrument of measuring temperature range is 200 ~ 650 ℃, permissible error are two process about 1% of the scale. The thermometer and the rod of glass liquid thermometer USES similar, but can be used under the condition of higher mechanical strength.

the anti-corrosion metal thermometer unique design have created favorable conditions for its application, and has more extensive application in industry.
