Electric contact bimetallic thermometer
Product Model:WSSX
Main technical parameters

(1)Electric contact type: Upper and lower limit contact 、 single upper limit contact 、 double upper limit contact.
(2)Accuracy class:
a.Upper and lower limit electric contact 、single upper limit electric contact:class1.5 ;
b.Double upper limit electric contact:the first upper limit is class 1.5;the second upper limit is class 4;
c.The setted error of contact is 1.5 times of the indicating value basic error.
(3)Rated power on contact 10W:
a.The maximum working voltage on the contact is 220V AC and maximum working current on the contact is 1A(non inductive
load );
b. Working voltage recommended is lower than 36V , but shouldn't be less than 12 V to guarantee that the contact moves reliablly.
(4)Dial plate nominal diameter:100mm 、60mm.

(5) Time constant, nominal pressure, jacket material are as same as WSS thermometer.
