MAINHO Safety Gas Thermocouple

Safety thermocouple NS / NC / ECO / ELP /ELC Mainho

The thermocouple is a safety device that automatically shuts off the gas at the tap if the flame on the gas ramps is accidentally extinguished.

At the end of this thermocouple, a calibrated probe transmits an electrical signal to an electrode incorporated in the gas valve.

This device is fitted to gas cooking appliances.

• ECO - NE - NS - NC - ECO LINE series: T-100/821x400 - M8/100 L40 fitting
  
• FC Series: T-100/1137-500 - M9/100 L50 fitting
  
• PC series: T-100/1116-500 - M9/100 L50 fitting
• PB - PBV - PBI - ELB series: T-100/821x400 - M8/100 L40 fitting

The thermocouple consists of 3 parts.

- 1 metal wire (nickel + chromium alloy - type K) inserted in 1 tube (nickel + aluminum alloy (5%) + silicon - type K).

Both ends: (tip and terminal) soldered as the picture shows us.
- 1 copper tube serving as a channel for the first 2 parts.

When the tip is heated, the heat energy transformed into electrical energy creates a magnetic field.
This is used to open the gas tap valve. In the absence of flame, the spring relaxes and closes the gas supply.
Thermocouples are characterized by a letter which determines the operating temperature range.
