The accuracy of the pressure measurement depends on proper installation of the transmitter and impulse piping. The piping between the process and transmitter must accurately transmit pressure to the transmitter. Mount the transmitter close to the process and use a minimum of impulse piping to achieve the best accuracy. Keep in mind, however, the need for convenient access, safety of personnel, practical field calibration, and a suitable transmitter environment. In general, install the transmitter to minimize vibration, shock, and temperature fluctuations.

Do not apply torque directly to the electronics housing. Rotation between the electronics housing and the process connection can damage the electronics. To avoid damage, apply torque only to the hex-shaped process connection. Use a backup wrench on Process Connection when installing an adapter.

ENVIRONMENTAL CONSIDERATIONS

Temperature

Moisture and Corrosives

Hazardous Locations Installations

Mount the transmitter in a manner that minimizes variations in ambient temperature.

The transmitter is designed to resist attack by moisture and corrosives. The electronics module is fully encapsulated and mounted in a compartment that is sealed from the power-side conduit entries. O-ring seals protect both compartments when the covers are installed.

In humid environments, it is possible for moisture to accumulate in the conduit lines and reach the terminal compartment of the transmitter housing. To prevent moisture from entering the terminal compartment, mount the transmitter at a high point in the conduit run, if possible. Also, remove the terminal compartment cover periodically and inspect the terminals for moisture and corrosion.

Rosemount 2088, 2090P, and 2090F transmitters are designed with explosion-proof electronics enclosures and circuitry that complies with intrinsic safety requirements and non-incendive operation. Individual transmitters are clearly tagged with approvals. Refer to Section 5: Specifications and Reference Data for a complete list of available approvals. To maintain certified ratings for installed transmitters, install with applicable installation codes and approval drawings.

NOTE

Once a device labeled with multiple approval types is installed, it should not be reinstalled using any other approval types. Permanently mark the approval label to distinguish it from unused approval types.
