What to do if Emerson Rosemount 400 Accessories reading seems wrong?

  Gloria CollinsAug 3, 2025
  If the Emerson Accessories reading seems wrong, it may be due to several reasons. Bubbles might be trapped in the sensor, so ensure the sensor is properly oriented in the pipe or flow cell and apply back pressure to the flow cell. Alternatively, the temperature correction algorithm might be incorrect, so verify it's appropriate for the sample. Also, the cell constant could be wrong; confirm that the correct cell constant has been entered in the transmitter and that it is appropriate for the conductivity of the sample.

  An off-scale reading on your Emerson Accessories can stem from several causes. First, verify the wiring is correct. Second, check the temperature element for open or short circuits. Next, ensure the sensor is completely submerged in the process stream. Also, check that the Variopol cable is properly seated by loosening the connector and reseating it. Finally, the sensor itself may have failed, so perform isolation checks.

  A sluggish response in Emerson Accessories can be caused by a couple of things. First, the electrodes may be fouled, so try cleaning them. Second, the sensor might be installed in a dead area in the piping; if so, move the sensor to a location more representative of the process liquid.
