I. Product Overview
Universal bimetal thermometer is a kind of field instrument for measuring medium and low temperature. Bimetal thermometer can directly measure the temperature of liquid, steam and gas medium in the range of -80℃ ~ +600℃ in various production processes.
2. The main characteristics
On-site display temperature, intuitive and convenient; Safe and reliable, long service life; Various structure forms can meet different requirements.
3. The working principle
Universal bimetal thermometers are based on bimetal sheets 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.
4. 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
