Rosemount 2088 and 2090

Access Requirements

When choosing a mounting location and position, take into account the need for access to the transmitter.

Make wiring terminations through the conduit openings at the top of the electronics housing. The field terminal side of the transmitter is clearly marked on the transmitter neck. Test terminals are incorporated on the terminal block; you do not need access to the electronics compartment to perform calibration procedures.

The transmitter electronics compartment contains the electronics module with failure mode and security jumpers, and the optional LCD meter. Consider the need for access to both compartments when installing the transmitter. Refer to Figure 3-5 for transmitter dimensional drawings.
