specifications
By blowing nitrogen or other gases, harmful gases are sent out of the protective tube, thereby improving the life of the thermocouple. It is an indispensable temperature measuring device in a 300,000-ton synthetic ammonia plant.
Electrical outlet: M20X1.5, NPT1/2
Accuracy class: I, II
Protection level: IP65
Nominal pressure: normal pressure
Generally, it refers to the static external pressure that the protection tube can withstand without breaking at normal temperature. The test pressure is generally 1.5 times the nominal pressure. In fact, the allowable nominal pressure is not only related to the material, diameter and wall thickness of the protection tube, but also It is related to its structural form, installation method, insertion depth, and flow velocity and type of measured medium.
The thermal resistance is 15-35°C, the relative humidity is not more than 80%, and the test voltage is 10-100V (DC). The insulation resistance between the electrode and the outer sleeve is ≥100MΩ.
The temperature of the thermocouple is 20±15°C, the relative humidity is not more than 80%, and the test voltage is 500±50V (DC). The insulation resistance between the electrode and the outer sleeve is ≥1000Ω.M
