Trigon™ BPG552 Bayard-Alpert Pirani DualGauge
For applications that require a measurement range from UHV (5 x10-10) down to ATM (1000 mbar) theTrigonTM family contents the dual technology BPG552 gauge.
BPG552 consists out of an Bayard-Alpert Hot Ionization sensor element as well as out of a classical, robust and reliable Pirani sensor element. Besides of extending the usable process to base pressure measuring range of BPG552, the integrated Pirani also automatically switches on/ off the Bayard-Alpert high vacuum sensing element, depending on unhealthy pressure changes during the process.
Combining technologies reduces the complexity of installation, setup, and integration, thus reducing cost and valuable tool space.
The supported Bayard-Alpert dual filament offers superior accuracy, repeatability and longevity. The removable calibration data chip, that comes along with the easy to install BPG552 spare sensor, to secure a seamless accurate process measurement, enables a higher bakeability of the sensor unit. BPG552 is available with analog output or EtherCAT interface option. Both enable easiest system integration.
The TrigonTM BPG552 can also be operated in conjunction with the INFICON Vacuum Gauge Controller series VGC501, VGC502, VGC503 or with other control devices.
