product manual:

       WSSX electric contact bimetal thermometer is used in the production site to automatically control and alarm the temperature. Directly measure the temperature of body, steam and gas medium in the range of -80 ~ 500 ℃ in various production processes.

       Features:

       · On-site temperature display, intuitive and convenient;

       · With automatic power off and alarm function;

       · Safe and reliable, long service life;

       · A variety of structural forms to meet different requirements.

       working principle:

       The 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 is activated to automatically control and alarm.
