221B 10-25,000 Torr Baratron® Bakeable Differential Pressure Transducers
Overview
The 221B Baratron® is a differential capacitance manometer with remote electronics which allows the sensor head to operate at temperatures up to 150°C. The Type 221's electronics are housed remotely from the sensor, allowing it to be baked at 200°C with the interconnecting cable removed.
- 10 to 25,000 full scale pressure range with 0.5% of reading accuracy
- 0 to 10 VDC analog output proportional to differential pressure
- Remote electronics allow the sensor to operate at temperatures up to 150°C
- Inconel®/Stainless Steel sensors resist corrosion
- All-metal sensor eliminates problems associated with glass, mercury, and liquid gauges
