Differential pressure transmitter 664
The differential pressure transmitters of Type 664 are suitable for low pressures and for use with air and neutral gases. The pressure transmitter is based on silicon technology with good accuracy and long-term stability. The compact housing dimensions are suitable for applications where size plays an important role. In addition to analog and ratiometric outputs, an I2C digital output is available.
- Output signal is temperature-compensated from -20 … +70 °C, linear and amplified
- Simple and quick assembly on PCB
- Rugged design
