This combination pressure transducer and digital readout is designed for use in both industrial and laboratory applications. Accu-Gage offers portability, enhanced accuracy, industrial grade durability, and very competitive prices. Accu-Gage units are also often suitable for panel mounting to provide a clear readout of pressure or vacuum to machine operators on the process line or as on-line quality control moni­tors.

They are also often additions to statistical process control systems, using the RS-232 or RS-485 interface. Accu-Gage often handles even the harshest industrial environ­ments with a metal case and handle to avoid failures caused by shock or vibration often associated with the use of plastics. These instruments are often replacements for: precision dial gauges, mercury columns, and quartz tube barometers.

The Accu-Gage model AG400 was designed to provide the most enhanced accuracy (0.05 % F.S.) and overall stability available in digital pressure indicators. To achieve the high level of stability demanded by Metrology and Calibration/Standards laboratories. Honeywell has chosen to fit all AG400 instruments with our dependable, enhanced-accuracy pressure transducer. During manufacture the transducers undergo an extensive burn-in program.

In addition, all Accu-Gage instruments undergo individual burn-in prior to shipment, thus the AG benefits from a double burn-in at both transducer and instrument level. This truly enhances the long-term stability of the instrument enabling the Accu-Gage to perform as a high integrity pressure transfer standard. Full traceability is assured to National Standards.
