Pt200 high temperature EGT sensor

Description

Pt200 automobile exhaust gas high temperature sensor，With the implementation of Euro IV standards, exhaust emissions and complete combustion must be controlled through high-temperature measurement. Exhaust measurement will become increasingly important for the protection of accessories and monitoring of exhaust systems.

The temperature chip of Pt200 EGT sensor complies with DIN60751 imported Heraeus chip,which has high accuracy and excellent stability in high temperature environment;The probe tip shell special structure design, open die, four channel pressure groove design, to ensure the chip response time is fast;The chip and wires are welded together and protected and filled with stainless steel pipes. The stainless steel material undergoes special high-temperature treatment, and the INC600 stainless steel has a colored and glossy surface, effectively increasing the oxidation and corrosion resistance of the stainless steel surface;The connector of the measuring end is specified by the customer, and the insertion depth can be customized.
