Features and Accessories
The BGA244 consists of a compact package which includes the resonant cell, acoustic
transducers, sensitive electronics and advanced signal processing. It can be powered
over USB or +24 V and can interface to external devices by computer interface or
analog signals and features a touch screen LCD to configure and monitor
measurements.
There are two models in the BGA244 series: the standard BGA244 and the BGA244E
(enclosure). Both models share the same acoustic resonant cell, transducers, signal
processing and basic computer interfaces. The standard BGA244 is available with
several options. See Appendix B for information about the BGA244E.

Electrical Connections
All versions of the BGA244 can be powered via their USB connector. This can be
connected to a computer, a powered USB hub or a USB charger. Instrument functions
can be controlled over either the USB or RS-232 computer interfaces. See Figures 1 & 2
(page 6) for the connector locations.
There are three LEDs that indicate the status of the BGA244.
