28 16 Silicon Nitride Ceramic Thermowells Thermocouple Protection Tube For Temperaturer Sensor - China

price: contact company for price

Product Description

Thermocouple’s long- time stability and service life will be up to outside
protection tube. Thermocouple shielded by silicon nitride thermocouple sheath
will quickly react to temperature due to its good thermal conductivity and
thinner wall thickness. Silicon nitride thermocouple protection tube is for
continuous temperature measurement and protect thermocouple without erosion.
