Bimetal thermometer

Product Description:

1、 Product Overview

The WSS series bimetallic thermometer is an on-site detection instrument for measuring low and medium temperatures. Bimetallic thermometers can directly measure the temperature of liquid, vapor, and gas media within the range of -80 ℃ to+600 ℃ in various production processes. The structural forms of bimetallic thermometers are divided into radial, axial, and universal as shown in Figure 1, and the installation varies depending on the structure.

2、 Main features

On site temperature display, intuitive and convenient; Safe and reliable, with a long service life; Multiple structural forms can meet different requirements.

3、 Working principle

A bimetallic thermometer is composed of bimetallic sheets wound in a circular curved shape. When one end expands due to heat, it drives the pointer to rotate, and the working instrument displays the corresponding temperature value.

4、 Technical parameters

1. Scale dial nominal diameter: 60mm, 100mm, 150mm

2. Accuracy level: 1.0, 1.5

3. Thermal response time: ≤ 40S

4. Protection level: IP55

5. Angle adjustment error: The angle adjustment error should not exceed 1.0% of its range

6. Return difference: The return difference of the bimetallic thermometer should not exceed J. of the basic error limit d value

7. Repeatability: The repeatability limit range of bimetallic thermometers should not exceed the basic error limit J 1/2 of the D value
