The GSP-029 is the PRO version of the GSA-029 Duct pressure for left and right engines on the B737. It is based on a dual concentric needle gauge is and has the proper faceplate for the L/R in the overhead panel. The housing is circular. The stepper motor gives very smooth needle movement.
The GSP-029 comes standard with a bezel. You must make sure that the diameter fits your panel.
The gauge is backlit (not from above like the standard GSA-029) but really from behind. The needle is also backlit. we use LED for backlighting, so with longer life-cycle and less heat generation.
The lighting is software dimmable.
The gauges can be used with our standard GSA-055 or (for professional users) with our GSA-RS232 or RS-422 interface. The GSA-RS232 or RS-422 in combination with an optional Serial port server makes it possible to drive our gauges over a LAN connection.
The gauge can be front mounted and could be fixed with brackets (optional)
the PRO range gauges for the OVH panel are different from the standard products. instead of a square PCB construction, we use a cilindrical pcb and housing.
The measurements are also different. See the technical data for the detailed information.
