The G-Tran Series are vacuum gauges developed to meet the need for more centralized and compact systems by (1) lowering equipment costs, (2) saving space, and (3) reducing wiring. Models come in three basic types: sensor units, box units and display units. Units can be combined to adapt to the application.

• Sensor units are analog units with the gauge head and measurement circuit integrated into a single structure.

• Box units have a microprocessor, with the circuit separate from the gauge head.

• Sensor units output analog signals and set points.

• Box units output pseudo-logarithmic signals and set points.

• Display units output pseudo-logarithmic signals and set points independently.

• Box units enable RS-485 multi-drop connection.

• Display units use DIN-standard sizes (48 x 48 /96 x 96 mm).
