Description

I. Product Overview

WSS series bimetal thermometer is a kind of field measuring instrument to measure medium and low temperature. Bimetal thermometers can directly measure the temperature of liquid, steam and gas medium in the range of -80℃ ~ +600℃ in various production processes. Bimetal thermometers are divided into radial, axial and universal forms, as shown in Figure 1. Different structures are not the same for installation.


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

Bimetal thermometers are based on bimetal sheets that are wound and curved in a circular manner. 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 plate: 60mm, 100mm, 150mm

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
