221B Baratron® Differential Capacitance Manometer
(10-25,000 Torr) Remote Electronics, Bakeable to 150°C
The 221 Baratron® is a differential capacitance manometer with remote electronics which allows the sensor head to be baked up to 150°C. The Type 221's electronics are housed remotely from the sensor, allowing it to be baked at 200°C (with interconnecting cable removed). Input power is ±15 VDC and output is 0 to +10 VDC. The 221 provides ±0.5% of Reading accuracy.
