Pressure Transmitter

How Do Pressure Transmitters Ensure High Accuracy in Process Control Applications?

• High-performance piezoresistive sensing core: Adopts premium silicon piezoresistive pressure chip to capture tiny pressure variations. The built-in precision integrated circuit converts weak millivolt signals into standard 4-20mA/0-10V output, laying a solid foundation for consistent high measurement precision.

• Strict temperature drift compensation design: Optimized circuit suppresses thermal zero and sensitivity drift below 0.03%FS/℃. It offsets reading deviations caused by ambient and medium temperature changes, maintaining stable accuracy across wide working temperature ranges from 0℃ to 100℃.

• Multi-grade precision calibration options: Available with 0.1, 0.3 and 0.5 full-scale accuracy grades via factory standardized calibration. Each unit undergoes full-range calibration to eliminate linear errors, matching different high-standard industrial control measurement demands.

• Anti-interference sealed stainless steel structure: Fully stainless steel sealed housing with IP65 protection isolates internal circuits from dust, moisture and corrosive media. The shock-resistant structure weakens vibration interference from pumps and compressors to avoid signal fluctuations.

• Isolation diaphragm anti-blocking design: Flush flat diaphragm prevents viscous fluid, sludge and particle buildup on the pressure sensing surface. It avoids measurement distortion caused by medium clogging, sustaining long-term accurate readings in food and sewage pipelines.

• Standardized stable signal output: Supports two-wire 4-20mA current signal for long-distance transmission without voltage attenuation. Compared with voltage output, it eliminates signal loss along cables, guaranteeing accurate data reception by PLC and control instruments.
