This a K-type thermocouple used on the Vems gauges and many engine managements. Range 0 - 1250 C.
This is a strong sensor with a 6mm body, ideal for Turbo use and very hot conditions.
Only the sensor tip, 10 to 15mm, should be in the exhaust stream. The thermocopuple cable can handle 250 C of heat.
The polarity on a thermocouple is important, because reverse polarity can damage the sensor. On the Vems K-Type thermocouple the green wire on the thermocouple cable go on the + side, and the white wire goes on the negative - side.
VEMS makes diy engine managements and a very popular EGT + Widemand gauge which is one of our most popular items and always on stock.
