Description
I. Introduction
The WSS series bimetallic thermometer is a field measuring instrument for measuring medium and low temperature. The bimetallic thermometer can directly measure the temperature of liquid, steam and gas medium in the range of -80 to +500 C in various production processes. The anticorrosive bimetallic thermometer is coated with polytetrafluoroethylene F46 on the bimetal thermometer bushing. It is suitable for temperature measurement in various corrosive medium of petrochemical industry. It is a special temperature measuring instrument for chlor alkali industry.
Two, working principle
The bimetallic thermometer is based on a bimetallic strip circled and bent. When one end is heated and expanded, the needle is driven to rotate, and the working instrument displays the temperature value of the thermal potential.
Three, main technical parameters
1, product implementation standards:
JB/T8803-1998
GB3836-83
2. The nominal diameter of the dial is 60, 100 and 150.
3. Accuracy: 1, 1.5
4, thermal response time: less than 40s
5, protection level: IP55
6, the angle adjustment error should not exceed 1% of its range.
7, return difference: thermometer return error should not be greater than the basic error limit value.
8. Repeatability: the repeatability limit range of thermometers should not be greater than 1 / 2 of the basic error limits.
