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, where automatic temperature control and alarm control output are required. 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 withstand environmental corrosion

·On site temperature display, intuitive and convenient;

·Equipped with automatic power cut-off and alarm functions;

·Safe and reliable, with a long service life;

·Multiple structural forms can meet different requirements.

2、 Working principle

The stainless steel electrical contact bimetallic thermometer uses temperature changes to drive contact changes. When it is disconnected from the upper and lower limit contacts, it activates the relay in the circuit, thereby automatically controlling and alarming.
