Radial bimetal thermometer
Description
I. Product Overview
The radial bimetal thermometer combines two kinds of metal with different linear expansion coefficient together, one end is fixed, when the temperature changes, the thermal expansion of two kinds of metal is different, driving the pointer deflection to indicate the temperature, this is the radial bimetal thermometer, the temperature measurement range is -80~600C, it is suitable for industrial accuracy is not high when the temperature measurement. As a temperature sensing element, bimetallic sheet can also be used for automatic temperature control.
Two, the main characteristics
On-site display temperature, intuitive and convenient; Safe and reliable, long service life; Various structure forms can meet different requirements.
Three, the working principle
Radial bimetal thermometers are based on bimetal sheets that are wound into a circular curve. When one end is heated and expanded, it drives the pointer to rotate and the working instrument shows the temperature value.
Four, technical parameters
1. Nominal diameter of scale dial: 60,100,150
2, accuracy grade: 1.0, 1.5
3, thermal response time: ≤40S
4. Protection grade: IP55
5, Angle adjustment error: Angle adjustment error should not exceed 1.0% of its range
6, return error: bimetal thermometer return error should not be greater than the basic error limit J.D value
7, repeatability: bimetal thermometer repeatability limit range should not be greater than the basic error limit J.D value of 1/2
