Type PBTS1A
PORTABLE BARATRON® TRANSFER STANDARD
Designed with the cleanroom in mind, the PBTS1A is a portable single-channel high accuracy 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 25,000 Torr.
The system includes a Type 690 Baratron pressure sensor, a Type 670 signal conditioner/
display and an uninterruptable power supply all housed in a rugged wheeled caddy with an
extendable 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
The illustration to the right shows a typical
process set point verification. The PBTS1A’s
Type 690 transfer standard is removed
from its storage drawer and placed in close
prox-imity to the process tool’s manometer
port. This is facilitated by using a combination isolation valve such as the HPS® IDA™
valve. With the transfer standard connected
to the IDA valve’s access port, it can be
used to verify accuracy of the gauge and
check system set point pressures.
