Description

Wssx series stainless steel electric contact bimetallic thermometer dial is made of stainless steel. It is mainly used in the production site where the environment is corrosive or the site is food grade material and the temperature needs automatic control and alarm control output. Stainless steel electric contact bimetal thermometer can directly measure the temperature of liquid, steam and gas medium in the range of - 80 ~ 500 ℃.
1、 Features
·The shell material is made of stainless steel, which can resist environmental corrosion
·Display temperature on site, intuitive and convenient;
·It can cut off the power supply and alarm automatically;
·It is safe and reliable with long service life;
·Various structural forms can meet different requirements.
2、 How it works
The stainless steel electric contact bimetal thermometer uses the temperature change to drive the contact change. When it is disconnected from the upper and lower limit contacts, the relay in the circuit will act so as to automatically control and alarm.
3、 Main technical parameters
·Product standard: JB / t8803-1998 gb3836-83
·Nominal diameter of dial: 100
·Accuracy class: 1.5 (1.0)
·Thermal response time: ≤ 40s
·Protection grade: IP55
·Normal working atmospheric conditions: temperature - 25 ～ + 55 ℃, relative humidity ≤ 85%
·Set point error: the set point error shall not exceed 1.5 times of the basic error limit.
·Switching difference: the switching difference shall not exceed 1.5 times of the basic error limit.
·Switching repeatability: the limit range of switching repeatability shall not be greater than 1 / 2 of the basic error limit.
