BBMS2B System Components

The portable two-channel pressure standard system includes one or two Type 627B Baratron capacitance manometers, a Type 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.

Typical Application

In a a typical set up for process set point verification, the PBMS2B’s Type 627 reference standard 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 IDA valve’s access port 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.
