Abstract

A vibration measurement system (8) for a gas turbine engine (6) is provided. The vibration measurement system includes a first accelerometer (12) coupled to the gas turbine engine, the first accelerometer configured to transmit a first identifier (34, FIG. 3), a second accelerometer (13) coupled to the gas turbine engine, the second accelerometer configured to transmit a second identifier (46, FIG. 4) that is different than the first identifier, and a signal conditioning computer (18) coupled to the first and second accelerometers for receiving the first and second identifiers, the signal conditioning computer configured to determine which of the first and second accelerometers is connected to the signal conditioning computer. An accelerometer is also claimed comprising an identifier connection configured to transmit an identifier to a computer, said computer configured to identify said accelerometer based on the received signal. The accelerometer further comprises a positive connection and a negative connection connected to an amplifier and a ground connection connected to ground. The identifier connection may be coupled to the ground connection via a resistor. The system allows different accelerometer / engine balance coefficients to be used within the signal conditioning computer for the different accelerometers. The system may allow different accelerometer / engine balance coefficients to be used depending on whether an externally mounted or internally mounted accelerometer is used.
