AA02A Baratron® 0.1 to 1000 Torr Heated Absolute Capacitance Manometers
Overview
The AA02A Baratron® manometer is an advanced general purpose absolute heated capacitance manometer developed specifically for use in vacuum and pressure measurement applications where high accuracy and excellent repeatability are crucial to process success. These capacitance manometers are internally heated to 45°, 80°, or 100°C. They use state-of-the-art digital architecture throughout to produce the highest possible long-term performance and reliability.
- Full scale pressure measurement from 0.1 to 1000 Torr
- Sensor heated to 45°, 80°, or 100°C for up to 0.10% of reading accuracy
- Fully welded sensor built entirely from Inconel® and Incoloy® nickel alloys
- 0 to 10 VDC analog output proportional to absolute pressure
- Pushbutton zero adjustment of zero position up to 20% of full scale
- All-digital architecture and improved thermal management for long-term stability, improved accuracy, and increased reliability
