Absolute Pressure Transmitter (FKA & FKH High Accuracy)
The FKA high accuracy absolute pressure transmitter model and FKH high accuracy absolute pressure transmitter model accurately measure an absolute pressure and transmits a proportional 4-20 mA output signal.
The transmitter uses a unique high reliability micro-capacitive silicon sensorin combination with a state-of-the-art digital signal processing to provide exceptional performances in terms of accuracy and stability.
- Short delivery time
- Accurate measuring results independent of atmospheric conditions
- Significant process performance thank to 4D Gyration TM characterization
- High plant availability thanks to high reliability unique design
Technical benefits
- High accuracy and reliability
- Minimum inventory and design
- Minimum environmental influence
- HART communication protocols
- Application flexibility
- Programmable output Linearization function
- Burnout current flexibility
- Long term stability
