Qualified Life

The transmitter qualified life is dependent on continuous ambient temperature at the installation site (see Figure 6-1). Replacement of amplifier and calibration circuit boards at the end of their qualified life permits extension of the transmitter qualified life to the module qualified life. See Rosemount Report D8400102 for details.
