Bimetallic thermometer apply to live in low-temperature detection, direct measurement of liquids, gases and steam temperature, a mercury-free harm, the instructions clear, strong, resistant to vibration.All instruments of stainless steel materials, has a good waterproof, decay resistance performance.It is widely used in petroleum, chemical, metallurgical, textile, food and other industries.Can be directly measured in the process of various production - 80 ℃ to + 500 ℃ within the scope of liquid steam and gas medium temperature.
Bimetallic thermometer features
The scene display temperature, intuitive and convenient
Safe and reliable, long service life
Many kinds of structure forms, can meet different requirements
The working principle of
Bimetallic thermometer is based on the ring around the made of bent bimetallic strip.End is heated expands, turns the pointer, the instrument will show thermoelectric potential should value.
Main technical parameters of bimetallic thermometer
Execution standard: JB/T8803-1998;GB3836-83.
Dial nominal diameter: 60, 100, 150
Precision level: 1.0, 1.5
Thermal response time: 40 s or less
Protection grade: IP55
Angle adjustment error: error Angle adjustment shall not exceed 1.0% of its range
Back to the poor: double metal thermometer should be no greater than the absolute value of basic error limits.
Repeatability: the thermometer repeatability limit scope shall not cut more than 1/2 basic error limits the absolute value of.
