Information

China industrial pyrometer is a field detection instrument for measuring low and medium temperature. It can directly measure the temperature of liquid vapor and gas medium in the range of -80℃-+500℃ in various production processes. The main component of the China industrial pyrometer is a multi-layer metal sheet composed of two or more metal sheets stacked together. It works on the principle that two different metals expand differently when the temperature changes. It is based on a bimetallic sheet wound into a circular curved shape. When one end is heated and expanded, it drives the pointer to rotate, and the working instrument displays the temperature value corresponding to the thermoelectric potential.

The main element of the China industrial pyrometer is a multi-layer metal sheet that is laminated together. An instrument that can automatically and continuously record temperature changes. In order to improve the sensitivity of temperature measurement, the China industrial pyrometer is usually made into a spiral coil shape. When the temperature of the multi-layer metal sheet changes, each layer of metal expands or contracts by an unequal amount, causing the spiral coil to roll up or loosen. Because one end of the spiral coil is fixed and the other end is connected to a pointer that can rotate freely, the two metals have different volume changes when the temperature changes, so they will bend. One end is fixed, and the other end is displaced as the temperature changes, and the displacement is close to a linear relationship with the air temperature. The self-recording system consists of a self-reporting clock and a self-reporting pen. The self-reporting pen is connected with the magnifying lever and is manipulated by the sensing element. Therefore, when the bimetallic plate feels the temperature change, the pointer can indicate on a circular graduation scale. temperature to come. The temperature measurement range of this instrument is 200~650℃, and the allowable error is about 1% of the two steps of the scale. The China industrial pyrometer and the rod-shaped liquid-in-glass thermometer have similar uses, but can be used under conditions that require higher mechanical strength.

The working principle of the China industrial pyrometer is based on the principle that two different metals expand differently when the temperature changes. In order to improve the sensitivity of temperature measurement, the metal sheet is usually made into a spiral shape. When the temperature of the multi-layer metal sheet changes, each layer of metal expands or contracts by an unequal amount, causing the spiral coil to roll up or loosen. Because one end of the spiral coil is fixed and the other end is connected with a pointer that can rotate freely, when the bimetallic sheet feels the temperature change, the pointer can indicate the temperature on a circular graduation scale.
