MAINHO Safety Gas Thermocouple

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

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

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

This device is fitted to gas cooking appliances.

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

The thermocouple consists of 3 parts.

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

Both ends: (tip and terminal) soldered as shown in the picture.
- 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.
The latter is used to open the gas tap valve. In the absence of a flame, the spring relaxes and closes the gas supply.
Thermocouples are characterized by a letter that determines the operating temperature range.
