Product Description:
The stainless steel electric contact bimetallic thermometer dial is made of stainless steel material and is mainly used in production sites with corrosive environments or media containing food grade substances that require automatic temperature control and alarm control output. Stainless steel electric contact bimetallic thermometer can directly measure the temperature of liquid, steam, and gas media within the range of -80 to 500 ℃ in various production processes.
1、 Characteristics
·The shell material is made of stainless steel, which can resist environmental corrosion
·On site temperature display, intuitive and convenient;
·Equipped with automatic power-off and alarm functions;
·Safe and reliable, with a long service life;
·Multiple structural forms can meet different requirements.
2、 Working principle
Stainless steel electric contact bimetallic thermometer uses temperature changes to drive contact changes. When it is connected to the upper and lower limit contacts or disconnected, the relay in the circuit is activated to automatically control and alarm.
