Application
WSSP-401 WSSP-411 WSSP-481 all stainless steel integrated bimetal thermometer with pt100 thermal resistance
It is a field measuring instrument for low temperature measurement. It can directly measure the temperature of liquid, steam and gas in the range of -80 ℃ ~ 500 ℃ in a variety of production process, can be displayed on the spot, can also be remotely transmitted signal.

Features
1. On-site display temperature, intuitive and convenient;
2. Safe and reliable, long service life;
3. Various structural forms can meet different requirements;
4. Remote signal 4-20mA

Working principle
Bimetallic thermometers are based on the composition of a bimetallic strip wound into a toroidal curvature. When one end is heated and expanded, the pointer is driven to rotate, and the working instrument shows the corresponding temperature value.
Thermal resistance is designed and manufactured by using the basic principle that the resistance value of platinum wire changes with the change of temperature. According to the resistance value R(℃) at 0 ℃, it is divided into 10 ohms (index number Pt10) and 100 ohms (index number Pt100), etc. The temperature measurement range is large and is suitable for -200~850 ℃.
