PBMS2F Two-Channel Portable Baratron® Measurement System
Overview
Designed with the cleanroom in mind, the PBMS2F is a portable two-channel pressure standard that is designed for in situ applications. Equally at home on the bench as on the production floor, the unit may be used for any pressure measurement application in the range of 10-5 to 1000 Torr.
The system includes one or two 627H Baratron® capacitance manometers, a PDR2000 display and an uninterruptable power supply all housed in a rugged wheeled caddy with an extendible handle for easy towing. The caddy also includes an integral tilt stand which, when extended, places the unit at an angle of 15 degrees from the vertical, thereby improving visibility of the display when the unit is on the floor.
- Reduces downtime caused by removing the process gauge for calibration
- Eliminates the unnecessary replacement of properly functioning instruments
- Provides a diagnostic tool for troubleshooting

Features
PBMS2F Features
- Select from 8 ranges: 0.02 to 1000 Torr Full Scale
- Temperature-controlled 627F Baratron Capacitance Manometer provides stable measurements at 0.12% to 0.25% of Reading accuracy
- Inconel® and stainless steel wetted surfaces permit use with many corrosive gases
- Second channel may be used for another standard manometer or may be used to monitor the device under test
- Components are packaged in a convenient wheeled caddy which is readily moved about the production facility
- No warm up delays: an uninterruptable power supply maintains power to the manometer for 1 hour during transit
- Traceable to NIST which assists in compliance with government and industry regulations such as ISO9000
Typical PBMS2F Setup
The illustration shows a typical set up for process set point verification. The 627 reference standard of the PBMS2F is removed from its storage drawer and placed in close proximity to the process tool's manometer port. This connection is facilitated by using a combination isolation valve such as the IDA™ valve. With the transfer standard connected to the access port of the IDA valve via a short length of bellows tubing, the transfer standard can be used to verify the accuracy of the process gauge and check system set point pressures.
