226B Baratron® 0.2 - 1000 Torr Differential Capacitance Manometers
Overview
The 226B Differential Baratron® is a general-purpose differential capacitance manometer available in full-scale measurement ranges from 0.2 to 1000 Torr and can be configured with a wide variety of fittings, input/output signals, and electrical connectors. It is mounted in a rugged industrial-grade housing that minimizes external RF/EM interference on the electronics and when properly configured, is completely "drop-in" compatible with earlier Baratron® differential manometers.
- Differential pressure measurement from 1000 to 0.2 Torr
- Gas composition independent pressure measurement
- Fully-welded Inconel® sensor resists corrosion
- Four different analog output signals for unidirectional or bidirectional calibrations
