ERTA produces different types of thermocuples since 1990.

In addition to the standard thermocouples, ERTA is also capable of producing all types of special thermocouples with specified customer parameters such as; opening time, extinction delay time and mV values.

By the help of our existing CNC and machine park; all requested mounting collars, nuts, etc. can be produced in-house. Again, by the help of special automation machines produced by our company; ordinary, quick action and very quick action type thermocouples in all lengths and with different thermotips can be produced.

What is "Thermocouple"? 

Thermocouple is an important part of a safety device used on controls for gas fired home appliances. It consists of two different types of metals welded together at one end (hot junction) When the thermocouple?s hot junction is warmed up, an electromotive force (EMF) is produced. This millivoltage is used to hold open an electromagnet assembly in the gas control. If the pilot flames goes out because of drafts, etc. , the thermocouple will cool off and no longer generate electricity. This will allow the electromagnets to de-energize, close the gas valve, and prevent gas from continuing to flow to the main burner and pilot.
