WZP-120G WZP2-120G WZP-121G WZP2-121G Assembly RTD
Overview of WZP-120G WZP2-120G WZP-121G WZP2-121G Assembly RTD
According to national regulations, the production of assembled thermal resistance shall comply with PT100 platinum thermal resistance with international standard graduation number of IEC and cu50 copper thermal resistance with professional standard graduation number.
The ratio of the resistance value (R100) of the assembled thermal resistance temperature sensing element at 100 ℃ to its resistance R0 at 0 ℃: (R100 / R0)
Graduation number PT100: Class A R0 = 100 ± 0.06 Ω
Class B R0 = 100 ± 0.12 Ω
R0/R100=1.3850
Graduation cu50: R0 = 50 ± 0.05 Ω
R0/R100=1.428±0.02
Features of WZP-120G WZP2-120G WZP-121G WZP2-121G Assembly RTD
Compression spring type temperature sensing element, good anti-vibration performance;
High temperature measurement accuracy;
High mechanical strength and good pressure resistance;

Fold and edit the working principle of the assembly thermal resistance in this paragraph
Thermal resistance is to measure the temperature by using the characteristics of the resistance of the material to change when the temperature changes. When the resistance value changes, the working instrument will display the temperature value corresponding to the resistance value.
