Note: “t” is the measured temperature of the temperature sensing element. For platinum resistance and copper resistance, it is the absolute value of the temperature of the temperature sensing element.

公称压力 ● Nominal pressure of thermocouple (resistance) for power station temperature measurement

Generally refers to the static external pressure that the protective tube can withstand without breaking at normal temperature. The test pressure is generally 1.5 times the nominal pressure. In fact, the allowable working pressure is not only related to the protection tube material, diameter, and wall thickness, but also to its structural form, installation method, insertion depth, and the flow rate and type of the measured medium.

The measured current through platinum resistance does not exceed 5mA.
