双金属温度计

Application Bimetallic thermometer is a low-temperature measurement instrumentation site. It can direct measurement -80- +500 range of liquid, vapor and gases medium temperature of the various production processes. Characteristics site show that the temperature, intuitive convenience; safe, reliable, long life; variety of structure to meet different requirements. The principle of operation bimetal thermometer is made based around the shape of bent-shaped bimetal composition. Thermal expansion of one end, the driven pointer rotation, instruments will be showing temperature by the thermoelectric power. Main technical parameters product performance standards : JB/T8803-1988. nominal diameter plate scale: 60, 100, 150. accuracy grade: 1.0, 1.5 thermal response time: 40S protection levels: IP55 angle adjustment error: angle adjustment error should not exceed 1.0 of the range. backlash: thermometer backlash should not be larger than the absolute value of basic error.repeatability: repeat limit the scope of the thermometer should no more than limit the scope of the basic error limit absolute value 1 / 2.
