- 型号系列
- EJA438E
- Technical feature
- 远传隔膜 Seal Design：Built-in 远传隔膜 structure isolates high-viscosity, easily crystallizable, particle-containing and strongly corrosive media, prevents impulse line blockage, and avoids damage to the transmitter caused by media entering its interior.
- Technical feature
- Excellent high 温度 resistance：It can isolate heat from high-温度 media, adapt to high-温度 process working conditions, protect the transmitter body, and extend its service life.
- Technical feature
- Ultra-high measurement accuracy + ultra-stable performance：Accuracy up to ±0.1%FS with a turndown ratio as high as 115:1; long-term stability of ±0.2% over 10 years, requiring almost no frequent 校准 and saving maintenance costs.
