FRD SENSOR FD80B Explosion-Proof Pressure Transmitter, 4-20mA/HART Industrial Pressure Transducer
The FD80B is a high-precision and high-stability intelligent universal pressure transmitter developed by FRD Sensor. Equipped with imported diffused silicon core components, it adopts full digital temperature compensation and nonlinear calibration technology to accurately measure gauge pressure, absolute pressure and negative pressure of various media such as gas, liquid and steam. It features a wide measuring range from 0-5kPa to 260MPa with multiple precision grades optional, and is fitted with a high-definition LCD local display screen. Supporting multiple standard output signals including 4-20mA, RS485 and HART, it is fully compatible with various industrial control systems. With an optimized heat dissipation structure and IP65 protection grade, the explosion-proof transmitter has excellent overload resistance and impact resistance. It can operate stably and continuously for a long time under high temperature, closed and complex industrial working conditions, serving as an optimal core device for industrial pressure monitoring and automatic control.
Features
- High-precision & stable measurement: Optional precision of 0.1%/0.25%/0.5%F.S and long-term stability of 0.2%, ensuring accurate and error-free measurement data.
- Excellent working condition adaptability: 5 times overload resistance (1.2 times for range above 60MPa) and 2 times burst pressure (1.5 times for range above 60MPa), with strong impact and interference resistance.
- Explosion-proof & durable protection: IP65 protection grade and official explosion-proof certification, dustproof and waterproof, suitable for flammable and explosive industrial environments.
- Intelligent digital compensation: Built-in full digital temperature and nonlinear calibration algorithm eliminates temperature drift errors, maintaining stable measurement in high and low temperature environments.
- Low maintenance: Small size, lightweight, maintenance-free design, save operation cost.
- Strong anti-interference and high long-term stability.
