Stainless steel electric contact bimetal thermometer dial is made of stainless steel, mainly used in the production site environment is corrosive or the site is food grade material medium and the temperature needs automatic control and alarm control output occasions. Stainless steel electric contact bimetal thermometer can directly measure the temperature of liquid, steam and gas medium in the range of -80 ~ 500℃ in various production processes. · The shell is made of stainless steel, which can resist environmental corrosion. · The on-site temperature display is intuitive and convenient; · With automatic power cut off and alarm function; · Safe and reliable, long service life; · Various structure forms can meet different requirements. Two, the working principle of stainless steel electric contact bimetal thermometer is the use of temperature change to drive contact changes, when it and the upper and lower limits of contact or disconnect at the same time, so that the relay in the circuit action, so as to automatic control and alarm. · Product implementation standard: JB/T8803-1998 GB3836-83 · Nominal diameter of scale plate: 100 · Accuracy grade: 1.5 (1.0) · Thermal response time: ≤40S · Protection grade: IP55 · Normal working atmospheric conditions: · Set point error: The set point error should not exceed 1.5 times of the basic error limit. · Handover error: the handover error 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 J.D value.
