Radial bimetallic thermometer
Description
I. Product overview
Radial bimetallic thermometer combines two kinds of metal with different linear expansion coefficient, one end is fixed, when the temperature changes, the two kinds of metal thermal expansion is different, drive the pointer to deflect to indicate the temperature, this is the radial bimetallic thermometer, temperature range of -80~600C, it is suitable for industrial precision when the temperature measurement is not high. As a kind of temperature sensing element, bimetallic sheet can also be used for automatic temperature control.
Two, the main characteristics
On-site temperature display, intuitive and convenient; Safe and reliable, long service life; A variety of structural forms, can meet different requirements.
Three, the working principle
Radial bimetallic thermometers are based on a bimetallic sheet wound into a circular bend. When one end is heated and expanded, it drives the pointer to rotate, and the working instrument displays the temperature value.
Iv. Technical parameters
1, the nominal diameter of the dial: 60,100,150
2, accuracy level: 1.0, 1.5
3. Thermal response time: ≤40S
4. Protection level: IP55
5, Angle adjustment error: Angle adjustment error should not exceed 1.0% of its range
6, back error: bimetal thermometer back error should not be greater than the basic error limit J.D value
7, repeatability: bimetallic thermometer repeatability limit range should not be greater than the basic error limit J.D value 1/2
