Rosemount 2088 and 2090

Rosemount 2090F

The Rosemount 2090F sanitary pressure transmitter is designed to be installed directly to a sanitary fitting. The transmitter is available with either a 1.5- or 2-inch clamp connection.

When installing the transmitter to the sanitary fitting it is important to use the proper sanitary clamp and gasket (user-supplied). Check the clamp and gasket specifications before installing. Refer to Standard Sanitary Clamp Models in Figure 3-8 for a list of standard sanitary clamps, their respective maximum pressure ranges, and the recommended torque to be applied when mounting.

ELECTRICAL CONSIDERATIONS

Power Supply

The wiring terminations on the Rosemount 2088, 2090P, and 2090F are located in the side of the transmitter housing marked “FIELD TERMINALS.” Access to these terminations is required during installation and may be necessary during periodic calibration of the transmitter.

The dc power supply should provide power to the transmitter with less than one percent ripple. The total loop resistance load is the sum of the resistance of the signal wires and the resistance load of the controller, indicator, and other pieces of equipment in the loop. Note that the resistance of intrinsic safety barriers, if used, must be included. Figure 3-9 shows the transmitter power supply load limitations.
