WZP Pt100 rtd 1.temp range:-200-600C 3.material:SS304,316L, SS321 4.thread:M27*2 5.certification:ISO9001/CE

WZ series Industrial assembly type thermal resistance

 

1. Application

It is usually connected with display meter, recording meter and computer ect. To directly measure the temperature of liquid, vaper, gas and solid surface ranging from -200 to 600°C during various production processes.

2. Features

Simple structure and good stability performance.

High measuring accuracy.

High mechanical strength, good pressure-resisting performance.

3. Working principle

It is based on that when temperature of object changes, the resistance will change accordingly, to measure temperature when the resistance value changes, the working meter will display relevant temperature.

4. Main technical parameters

Standard

IEC751

JB/T 8622-1997

JB/T 8623-1997
