W W W . M K S I N S T . C O M Calibration & Service Products 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. Features & Benefits • Provides for in situ verification of process gauge accuracy and tool-to-tool consistency - Reduces downtime caused by remov ing the process gauge for calibration - Eliminates the unnecessary replacement of properly functioning instruments - Provides a diagnostic tool for troubleshooting • Select from 10 ranges: 0.1 to 25,000 Torr Full Scale • Premium Type 690 transfer standard Baratron® Capacitance Manometer provides a wide measurement band at 0.05% or 0.08% of Reading accuracy • • • • • Inconel® and stainless steel wetted surfaces permit use with many corrosive gases Components are packaged in a wheeled caddy which is conveniently moved about the production facility No warm up delays: an uninterruptable power supply maintains power to the manometer for 1 hour during transit The transducer is traceable to NIST which assists in compliance with government and industry regulations such as ISO9000 Components are CE compliant 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.
